Status code: 9 MATRIX_Singular_OR_INDEFINITE

EmailFacebookLinkedInTwitterShare

Some error messages make you wonder, what does it take to get something simple done? I have often wondered how coders come up with names for errors and claim them to be logical? One common bane is “Status code 9." This message is often followed by a second message claiming there aren’t enough restrains defined. Basically, the software cannot figure out how parts are interacting in 3D space. Every solid or surface body has six degrees of freedom available to […]

Do your Designs Sing?

EmailFacebookLinkedInTwitterShare

We often consider design to be safe if prototypes work out fine, or if over a period of time legacy data has paved the way. If comfortable with analysis, static tests are the first line of defense to prove concepts. Knowing loading conditions, and component interaction with its environment we identify success with an appeasing color chart of blue and green colors. Could it be we missed a few nuances making our best design not perform as planned? Let me […]

Do you need a slam dunk test?

Static studies assume loads are constant or applied very slowly until they reach their full values. Because of this assumption, velocity and acceleration of each particle of model is assumed zero. As a result, static studies neglect inertial and damping forces. For many practical cases, loads are not applied slowly or they change with time or frequency. For such cases we use a dynamic study. The software calculates response of model by accumulating the contribution of each mode to loading […]

Do you need a specific type of machine to run Analysis?

Well the question cannot be answered without understanding what is it being utilized for? Depending on the type of analysis versus size of analysis problem; the range could vary significantly. In this link I will try to give an over view of what should be considered. RAM Having a lot of RAM on your machine is like having a vehicle with a lot of Horse Power. The difficult the terrain the stronger the engine should be. In SOLIDWORKS and COSMOS […]

What makes Apple keep coming out with coolest looking gadgets that meet both function and style of current genre? Why hasn’t Microsoft seen a slump in its growth rate since its conception? I think we all know Innovation is driving all of them. Is that the case in your organization? Software vendors keep pushing the idea of making analysis a routine part of design – especially up front in the cycle. The benefits claimed: companies can spot and fix problems […]

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 […]

Wisconsin / Illinois COSMOS User Group

EmailFacebookLinkedInTwitterShare

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 […]
