Meshfree simulation for meshes?…

Simplicity of operation.  Over 80% of the several hundred users who filled  out the feedback survey indicate that simplicity of operation is  particularly important feature of the software.  Surprised?   Not  reliability, not predictability,  not freedom from mesh,  and not even  ability to handle complex NURBs geometry, which was selected by just  over 50% of respondents and came in as a distant second important feature.



Now, keeping things simple is anything but… Continue

Over the last fifty years, Finite Element Analysis (FEA) has become the predominant tool in engineering analysis, offered by virtually all Computer Aided Engineering (CAE) vendors and used in a majority of analysis and simulation applications. Yet, the acceptance and adoption of CAE tools has been slow, largely because they are still difficult to apply to realistic geometric models. By all accounts, the main culprit is not the FEA method itself, but the process of preparing geometric data in a… Continue

That is right -- this is how long it took to transform a simple idea of in-situ analysis into a working commercial product. The fundamental principle is straightforward: once you have a geometric representation of a shape, you know everything there is to know about it, and should be able to compute whatever is needed directly from this native representation, without converting into something called "mesh". Why would anybody want to deal with repair, simplification, defeaturing, bad meshes, and… Continue
