Splitting Surfaces for FEA

EmailFacebookLinkedInTwitterShare

Splitting a face of geometry in SOLIDWORKS can be very useful in FEA for a number of reasons: Isolating a location to specify a load/restraint Specifying areas to apply mesh control Reducing the time to solve by cutting down the areas of a no-penetration contact condition, and so forth. There are two methods to split a face in SOLIDWORKS that the user can exploit for analysis purposes: a) SPLIT LINE COMMAND Insert > Curve > Split Line This tool can […]

Nodal versus Elemental Stresses

EmailFacebookLinkedInTwitterShare

A common question that comes up in my training classes is : What should be examined – Nodal Stresses or Elemental Stresses? When running a COSMOS analysis, the solver internally evaluates the stresses for each element in the model at specific locations inside the element (also called as Gaussian or Quadrature points). These points form the basis of numerical integration schemes used in Finite Element codes. The number of points selected is determined by the type and quality of the […]

Tackling the LARGE DISPLACEMENT Error Message

EmailFacebookLinkedInTwitterShare

What does one do when he/she sees the error message shown in the picture: This error message is probably one of the most common ones that a COSMOS user encounters in analysis. The first reaction that one gets is that this is impossible. You know for a fact that the load cannot possibly cause large deflections. Statistically speaking, the confidence levels on FEA drops drastically at this point, and I would not blame you for it right now (later, maybe)!! […]

Analysis is a lot like training for the marathon. You can easily upgrade from being a novice to becoming a power user if you strategize your approach towards FEA. Use the guidelines below to chart out a plan to become an FEA expert: Train hard: It is impossible to overstate the importance of FEA training. While analysis has come a long way in becoming a much simpler tool to use, it is still a tool that requires good mentoring to […]

Users Often Get Confused about using COSMOS network seats with SOLIDWORKS stand alone licenses. This is not an uncommon scenario as companies want to save money and share the same COSMOS seat amongst multiple users. Here is a low down on what needs to be done. Instructions to use COSMOS 2008 with a SolidNetWork License (SNL) file: 1. Save and unzip the SNL_AllowMultHostIDs.zip to any location on the server. (call CATI 888-285-2284 or email us support@cati.com)2. Clicks on the Registry […]

Finding THAT Needle in a Haystack!!

EmailFacebookLinkedInTwitterShare

I was reading the SOLIDWORKS Community online journal when I came across an interesting passage that underscored the need for an integrated data management solution to keep track of analysis results. http://www.solidworkscommunity.com/feature_full.php?cpfeatureid=26119 At a time where huge amounts of data circulate through computers and servers, it is almost way too easy to misplace information. Haystacks of information are growing ever larger and the needles ever smaller!! It is a routine procedure in a battery of analysis tests to make numerous […]

Planning for Finite Element Analysis – Part II of IV

GATHERING PERTINENT DATA Based on the industry, each customer has stringent requirements that are to be met by either the design, or the Finite Element Analysis results, or both. For example, a customer A can have a requirement that states that the factor of safety of the design should be at least 2, and that the maximum deflection on the design should not exceed 0.10 inches upon full-load application. Customer B might require the design to be within a certain […]

Planning for Finite Element Analysis – Part I of IV

With the integration that is available today between CAD and FEA, it is not uncommon to take model setup for granted, and put out fires at the end if there are conflicting results. For a seasoned FEA user, this approach works effectively enough. However, a little planning ahead can go a long way in ensuring correct results. Analysis is a lot like tightrope walking. One misstep in the setup can cause results to look disastrous. However, if setup correctly, the […]

COSMOS is the FEA tool built to function right inside your SOLIDWORKS interface. It is intended to empower both specialists and designers/engineers with capabilities to analyze their designs in an easy and resourceful way, and understand the results with its extremely user-friendly post-processing features. Its efficient integration with SOLIDWORKS makes it all the more versatile. In-built features such as using design scenarios for What if scenarios and easy re-analysis of design changes makes the tool technically sound. The breadth of […]

What’s New in SOLIDWORKS 2008

EmailFacebookLinkedInTwitterShare

We’d like to thank many of you who attended one of our local “What’s New in SOLIDWORKS 2008” events. It was good to see friendly faces from training classes that I hadn’t seen in a while. It was also good to hear that business is growing for many of you. A few of you asked if the presentations could be made available to you. Many of you did not get to attend, but would like to flip through the presentations. […]
