Do design mode commands effect analysis? ... ie, fixing or mating in an assembly? I have done some structural runs with unmated/unfixed features without a problem, but on some occasions, the analysis will not run. Could this be because of a construction problem in the design mode, or would it be something in the meshing in the analysis mode?
One of the rule in FEA world as I have heard most of the time "Always use define sketches, features, parts, etc.".
Thanks Deepak ... by that do you mean fix and mate all the features in the design mode first, and is it proven necessary for the analysis?
Yes and idea will be that when you do the analysis and need for some design change, you'll know which thing to change and how much.
That is not really the point. Its not a matter of concept design, its whether mating and fixing in the design mode will or will not effect or prevent the analysis from running.
Hi Chris:
From what I know, the FEA simulation does not "read" the SolidWorks Mates. All boundary conditions (fixtures, sliding conditions, contact, etc.) are input using the FEA Simulation side of the software. However the opposite is true for Motion Simulation. It does "read" the SolidWorks Mates. So, if you're doing an event-based simulation with both Motion and FEA, you can see that you will need to watch-out for SolidWorks assemblly mates (for the Motion portion), but you will not have to worry about Mates for the FEA Simulation (or just "Simulation", as they call it). Hope that helps. -Tony
Thank you, Tony. That is the answer I was looking for. We frequently run analysis from imported step files, and as I'm sure you know, those kind of features are not imported with them. Thanks again.

Well sorry Chris but I had little knowledge on simulation and just shared what I know. But glad you got your answer.. Thank you, Tony
No Problem, Deepak. Thank you for sharing your thoughts.
