Computer aided engineering has always been a role of a specialist. This statement is very much evident from the fact that more than 50 percent of analysts today have a graduate degree; either an MS or a PhD. This is because these physics-based simulations are a lot more than collection of icons, toolbars and pull-down menus. Unless the user is well familiar with the core engineering aspect of the problem being solved as well as with the underlying governing equations that solve the problem, he is very likely to make an error in modeling that would lead to erroneous results. In such situations “a stress solver becomes a stress creator.”

If one dissects the subject of computer aided engineering, he would see several branches of it. The main ones are: finite element analysis, computational fluid dynamics, multi-physical simulation as well as multi body dynamics. Each of these branches have several sub-branches of it. For example, finite element analysis can be divided into structural analysis, thermal analysis, coupled analysis. The structural analysis can be further sub-divided into linear static structural, non linear static structural, linear dynamic, non linear dynamic etc. As one moves keeps digging inside, simulation becomes more niche and more specialized. This justifies the need of a specialist with many years of experience with advanced technical and academic credentials.

While we, at TATA Technologies do not provide work experience or academic credentials, we do transfer expertise in computer aided engineering and many other fields of engineering through dedicated technical trainings as well as on the job trainings. We offer software products specific trainings such as Dassault Systemes portfolio, Siemens PLM portfolio, Autodesk portfolio as well as several industry vertical trainings such as modeling of welds and connectors in automotive chassis, design for light weight etc. We do provide small sessions on best practices as well such as effective element selection in Abaqus, overcome convergence problems in non linear simulation etc.

We train people with various levels of experience and knowledge. The student may be a fresh designer out of college who has recently joined his first organization or may be a subject matter expert with years of design or simulation experience and trying to learn something new. As mentioned, we teach both software as well as methodologies and workflows.

If you have a high end engineering software in your organization that seems to be underutilized because of lack of human resource, please get in touch with us.

It’s all about Risk Mitigation. The quote you most often hear is “better as-built data leads to better designs”. It’s clear now that laser scanning
is a better workflow vs field measuring. Frequent trips to get it right can’t replace one trip to get it right the first time. We always hear theScan and CAD
devil is in the details and laser scanning, done right, records the details.

Field measurements, outdated documentation, delays, and travel time, all lead to inaccurate and late proposals. Once the proposal is accepted it’s up
to you to keep the project profitable. In some documented studies working from a laser scan has reduced rework to less than 2%.

Some benefits include:
• Provide access to the point clouds for all stakeholders, everyone is working from the same information
• Reduce the number of incidents from manual measurement errors.
• Reducing time onsite
• Fewer mismatches and design errors
• Advanced interference and clash detection for installations without onsite visits
• Consistent as-built documentation for design specifications

There is no doubt that working in 3D space is better than 2D alone. The issue has been getting to a 3D environment. Laser scanning provides this
in an economical and timely manner.

In the last several years, there hasn’t been a lot of ground-breaking additions to most 3D CAD software.  One of the more recent Autodesk Inventor developments in the last couple years has been the addition of the “Direct Edit” tool.  This recent addition can be used to edit models independently of any feature history.  This means you can edit models that were developed natively in Inventor, or imported as basic solid geometry from another CAD system.  The Direct Edit tool has a variety of functions including:

  1. Moving faces or solid bodies
  2. Sizing faces
  3. Scaling solid bodies
  4. Rotating faces or solid bodies
  5. Deleting faces

The “move” function has a “snap to” option where you can select geometry or a plane to set the new face termination distance.  Of course the default “offset” distance” is also available.  The “size” function allows for offsetting geometry, but there is also a diameter option that works particularly well with cylindrical shapes like hole or shaft sizes.  There are also functions within the tool to re-align the “triad” which allows for movement or rotation to be aligned with any edge or face in the model.

Once a model has been edited with the direct edit tool, you will notice that it will be documented in the model browser where it can be editing like any other feature in the Inventor model browser.  Each of the direct edit sessions will be listed as separate features in the browser, and each feature can be expanded out to modify any of the functions applied.

Overall, this is a tool within Autodesk Inventor that is well worth learning.  For more information, email us at Info.Americas@tatatechnologies.com

One of the more common issues that come accross our helpdesk is the failed Vault log in attempt.  We try not insult the intelligence of anyone calling in, so we forego the typical first response of “Did you type your user name and password correctly?” or “Is the server on?” (I wish other technology providers would do this to…)

The first thing I will do in this situation is to see if the list of Vaults is accessible.  This will tell me that we have valid connection to the server.  The list of Vaults can be accessed by the button with the ellipses as shown below.

login

Clicking this button should then show you the list of enabled Vaults on that server, as seen here.

vaults

If you get an error message here, then I will try a couple things.  There may be a proxy server in your environment, or some other kind of IP route settings.  We can try using the fully qualified domain name (FQDN) or the IP Address, as seen in the two images below.  The FQDN should be pretty easy to decipher.  The pattern is server name and the domain name (typically the part after the @ symbol in you work email address).  An example is server.domain.com; server is the server name (a.k.a. host name, third-level domain), followed by a period, domain is the name of the domain (a.k.a. second-level domain), and .com at the end, which could also be .org, or .net (a.k.a. top-level domain).

fqdn2

The IP address may not be as readily known.  You may try PING‘ing the server, which, if successful, responds with the IP address.  Some smart IT folks will disable the ICMP protocol (which PING is a part of), so you may just have to ask your network administrator for the IP.

ip

There may be one more thing to try, and that is to append a port number.  Adding a port number is valid on any of the three methods above; server only, FQDN, and IP address.  To specify a port number, just add a colon and the port number to the end.  If your Vault requires a port, you will have to contact your administrator to determine which port to use.

port

If, after all of this, there is still trouble logging into Vault, then it may be time to seek helpdesk support.

Autodesk Vault is a robust PDM system with sundry nuances and features.  In this post, I will be showing various links to websites that have a ton of great information.  These links will be useful for seasoned administrators to the first time end user.

First, help docs.  These online help docs from Autodesk are the definitive resource for anything and everything Vault.

If you have been using Autodesk Inventor for a while you may already know this, but there is a process for migrating Inventor’s “Content Center” libraries.  This should be done to ensure you don’t end up with duplicate parts (file names) for the same fastener, pin or other common part.  When libraries are migrated, it allows the new software version and its updated libraries to recognize that a particular existing component is being placed.  The existing model will be utilized in this case.  If the libraries are not migrated, a whole new set of model files will get created when you start placing component from Content Center in a new version of Inventor.

Here is the general procedure:

  1. Determine where your current style library is located.  It may be in the default location for individual users, or may be in a common location.
  2. Launch the “Autodesk Inventor Style Library Manager”.  This is a separate program in Windows that isn’t started from within Inventor.
  3. In the “Style Library 1” area browse to your old style library that you located in step 1.  It should say that “some style collections need migration”.
  4. Select the Migrate button at the bottom

I also recommend backing up an previous style libraries before migrating them.  There have been various accounts of libraries failing to migrate and becoming corrupted.  Making a backup and testing the migration is imperative if you have extensive modifications in your existing style library.

Typically when new software releases come out, there are always a few really key improvements that really stand out.  Many times, it is a cool new modeling feature, or maybe an entirely new approach to design.  In Inventor, this might be like the addition of Freeform Modeling or Direct Editing as examples.  Unfortunately these are features or techniques that might not be applicable to many users.

If you are using both Autodesk Inventor and Vault together however, you should probably pay attention to this one:  The Vault status icons in the “recently used” area.  These icons now clearly identify the current Vault status of one of your recent files when in the Inventor “Open” dialog box.  Is the file checked out?  Is the file checked in, and up to date in my workspace? Has someone else modified the file since I last worked on it?  Have I checked in my latest development ideas or new parts yet?  All of these can be determined simply by noticing the Vault status bubbles in the “Open” dialog box.

PDF Publishing

‘Nuff said.

*and there was much rejoicing*

Well, maybe I could add a little more detail. It has long been known that the PDF is the currency of visual data exchange. All too often, I work with users and organizations that have to print PDFs outside of Vault, creating an uncontrolled document. If you were using the item master (discussed by my colleague here), you could attach it to the item; however, keeping it up to date is still going to be a manual process.

Now, thanks to the #1 most requested feature being implemented, that will no longer be an issue. Vault will now publish PDFs as part of your release process (as part of a transition action in a lifecycle change). This file will be categorized differently than the native CAD file, or even the DWF visualization file. The new category is called “Design Representation,” which can then be assigned its own set of rules, properties, and lifecycles.

As of this release, we have the ability to publish 2D file formats: DWG and IDW; that means either AutoCAD based files or Inventor drawings can be published to PDF. At some point, Autodesk may need to add the 3D PDF generation that was added to Inventor recently – which, by the by, could be used to publish all of the new Model Based Definition (MBD) annotations Inventor 2018 has added. I suspect we could see 3D publishing in the next release, or even a mid-year “R2” release (if there is an “R2;” who knows at this point).

Questions, comments, and celebrations welcome.

When working with our customers, from time to time, we’ll get questions on why they see unexpected results in some of their searches. This typically happens when they search without wildcards (I’ll explain later). In this blog post, I hope to shed some light on what can be a confusing experience for some Vault users.

The search engine in Vault operates on a on a general computer science principle called general Tokenization. This process essentially chops up the indexed properties into chunks called tokens. When a user searches in Vault (either quick search or advanced find), the search engine will attempt to match the tokens in the search string to the tokens in the appropriate properties.  Before going further, I’ll explain how Vault does the slicing and dicing.

First, there are three categories of characters (for our purposes, at least); alpha [a-z, A-Z], numeric [0-9], and special [#^$, blank space, etc.].  Vault will parse the string and sniff out groups of characters belonging to a category.  For instance, ABC123$@# would be tokenized into 3 individual tokens:

  • ABC
  • 123
  • $@#

Again, what happened is that Vault saw the first character, A, and understood it to be an alpha character. Vault then asked “Is the next character an alpha, too?” to which the answer was yes, so the token became AB. C was then added to the initial token, as it too was an alpha character.  However, the answer was “No”, when it came to the character 1.  Vault finished its first token and began the next one, now that it sensed a different category of character. Vault continued this line of questioning with the subsequent characters.

Another example might be a file name like SS Bearing Plate-6×6.ipt. Here, we have 8 tokens:

  • SS
  • Bearing
  • Plate
  • 6
  • x
  • 6
  • ipt

Now, you may have caught the missing period. Vault will only tokenize six special characters – all others are ignored. These special special characters (sorry, had to do it) are:

  • $ (dollar sign)
  • – (dash)
  • _ (underscore)
  • @ (at symbol)
  • + (plus)
  • # (octothorpe, aka number sign)

So now where do the unexpected results come in? This usually happens when an incomplete token is used without wild cards. For example, a user wants to find a specific mounting bracket. This user then types in “mount,” expecting that to be enough. In our hypothetical Vault environment, the results would return “Fan mount.ipt” but not “Mounting bracket.ipt” like they intended. Why? Remember that Vault is trying to match exact tokens (again, without wild cards).

If the user had entered mount*, the results would return the expected “Mounting bracket.ipt” as the user intended.

Moral of the story?  Always use wild cards…always.  No, really, all the time.  For everything.
