FEA on weldments -- changing structural members

Question asked by Jim Andrews on Jul 8, 2010

I've been using COSMOS/M since the early 1990s, but recently joined the 21st century and started using SolidWorks + Simulation.  I am not very proficient at either.  I would appreciate it if someone could walk me through a roadblock I've encountered.


I am analyzing a welded structure with beam elements.  Ultimately, I want to optimize the structure for cost, but for now, just assume that there is one particular structural member which I would like to change based on the FEA results.  For instance, let's say I have a 4 x 4 x 0.25 square tube that is a bit highly stressed, so I'd like to change it to 4 x 4 x 0.375 and rerun the analysis.


Is there an easy way to make this change without having to redefine all my loads and boundary conditions?  Thanks in advance for any help . . .
