Ignoring Radiation can cause Eggs to Boil…

I was at COSMOS User Group meeting in Racine, WI. Knowing a good majority of them, I was very happy to be surrounded by familiar faces. You know summer has kicked in; when everyone keeps talking about latest grill on the market helping their culinary skills to utopian levels. As everyone contributed their fascinating story, one caught my attention the most. An attendee claimed, keeping a tray of eggs close to the grill caused the eggs to boil. Having learnt […]

Trouble shooting Mesh: “Element 7413 belongs to unsupported element group”

EmailFacebookLinkedInTwitterShare

While working with complex geometry (having small features, chamfers, fillets, sharp corners) mesh it might fail. Many a times COSMOS tells you what node or element failed. The reason for failure is usually the element was over stretched in trying to accommodate for features. The next logical step would be to apply local mesh controls in regions of failure. But first we need to locate where is that node or element located. To do so. …. 1.           […]

The Front Fell off !!!

There are times, no matter how careful you are designs don™t work when tested. Hopefully, design team take it with a pinch of salt and has fun over beer. Bob Konczal, the CTO, at Computer Aided Technology Inc. found a video of an Englishman, explaining why the front of a tanker – ship (carrying 20,000 tons of crude oil) fell off. I am sure this is purely meant for entertainment, but point taken Bob all engineering teams should be using […]

The best way to evaluate design performance is by testing it. With ever reducing design cycle time, and multitude of projects every engineer needs to work upon virtual testing paves the way to save time and money.  On June 3rd an elite group meets up in Wisconsin trying to understand how fellow designers crank the most out of their designs. The Wisconsin / Illinois COSMOS User Group is made of individuals who go an extra step with conceptual designs. The […]

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)!! […]

The Ten Commandments of FEA

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 […]

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 […]
