Exclude parts from Simulation by suppressing in model

Adrian Tayne Feb 10, 2012 12:12 PM

I am attempting (so far unsuccessfully) to run stress analysis on a complex case assembly by simplifying it down to just the inner frame to start out with. My strategy was to suppress the features I wanted to exclude from the study in the model itself assuming that simulation would automatically exclude those suppressed features from the study. I appear to have been mistaken as all of the parts and subassemblies that i suppressed show up in the Parts section of the Simulation Tree.

Can someone please tell me that there's a way to have suppressed features automatically excluded from the study? I don't want to have to go back and exclude all those parts/sub-assemblies from the complete case... But I will if that's the only way to go about it.

So it looks like it is possible to exclude by suppressing in the model. i opened up a small subassembly from the case and tried suppressing various features with a Simulation study open and they were removed from the Simulation parts list. However, on the top-level assy, there are parts in the list that shouldn't be there. When trying to run a curvature based mesh (just for meshing troubleshooting), I'm getting interferences on parts that are suppressed. This is highly annoying and I can't explain it.

  When you suppress or unsupress in the model you have to remember to RMB the Study and choose Update all Components. You may have to do this after adding or removing features too. After doing this, check that all the bodies have material properties assigned.

    Peter, The parts were suppressed before I even created the study yet they still showed up in the Parts section of the tree. I have updated components several times since creating the study and the offending parts still persisted. I eventually solved this by exluding all the parts I didn't want. It was time consuming and I wouldn't want to have to do it on a regular basis.

      Adrian,
      
      I also work with large assemblies with hundreds of parts that I suppress for analysis purposes. So far, I haven't seen the problem you describe. Just wondering - any chance that there's a different configuration coming into play? You've probably already looked into that already - sorry I can't be of more help.

        I had not looked into that actually. This was a model someone else built so it didn't occur to me that there might be other configs. I tried deleting them and creating a new study, and the suppressed parts were all gone! I'm not positive that there wasn't something else screwy going on but this seemed to have worked. I can't understand why Simulation would look at a config other than the one that is active
