can anyone let me know the generalised modeling procedure for doing FEA inside SWX. I feel like modeling procedure has large influence on the ease with which you can do the analysis, can i get any documentation on this subject. thanks
I have seen a document on this forum on that but I'm not able to locate up right now

Usually when I do FEA, I make a copy of the model (Pack-and-go). This is to save the model in its current state and protect it from outside changes, especially if it is an assembly.
Once a copy is made, I am free to change whatever I wish. Sometimes I convert sheet metal to surface bodies. I usually get rid of gaps between welded components. Sometimes I use split curve to divide faces for application of forces or constraints or mesh refinement.
It's a bit more work going in, but sometimes I need better results than one can get by just throwing a mesh on a model.
Very good points made by Roland!
I like to use solidworks sheet metal features for components that are very thin and flat. SW 2009 and onward can automatically interpret these items as shell elements with the thickness already defined. I like this because it saves much time in the analysis (1/2 as many nodes compared to a solid).
Another alternative to the Pack -n Go method of Roland is the FEA configuration. At my company, others sometimes need ownership of parts and/or assemblies to do drawings. So I make an FEA configuration of all the things that need special attention (like Roland said, split lines for load application or mesh refinement) and leave a default configuration that will be used in the drawings. I also make fea configurations of assemblies (so I can turn on the fea part configurations) so that I can use them. I make a copy of the main assembly, but it uses the same parts as the parts the drawing people are working with. If I need to make a change, I change it, and then I KNOW that the drawing will get updated accordingly. No need to redo the change in another part document. It can be a pain working with files when you don't have ownership of all of them, though. (by "ownership", I'm referring to Solidworks PDM, btw)
That's part of my procedure. Use it if you like.
i got my answer got it downloaded from VRC recorded webcast, thanks
there u go
