    FEM on imported parts/assembly

    Alessandro Frattini
      Hi,
      I've imported a parasolid project from one our external designer.
      He uses NX.
      I would like to ask to you if I can plot the result on my coordinate system and not from original SolidWorks assembly coordinate system.
      For example in NX the Z is Y SW axis.
      When I import, you can understand the situation.
      Assembly is big, so I don't want to rotate or move the entire assembly.
      If I create a new coordinate system, can I set Simulation to show my FEM result to my new coordinate system ?

      Another question is how can I simplify parts to avoid lot of meshing time ?
      A lot of parts are cast parts, so they have lots of fillets.
      I can't use FeatureWorks (I tested but doesn't recognize fillets) because there are lots of cast parts.
      Simplify mesh is not good.

      Thank you for the possible suggestions,

          "how can I simplify parts"

          Inside of NX 6 exist FEMAP meshing engine.
          You can proceed solid tetra mesh and import it to Cosmos.
          Before CosmosWorks had geometry simplification engine.

          Exists a lot of variants and third side codes to simplify geometry
          Says in Ansys Workbench there are 2 possibilities:
          patch-undependent meshing
          virtual cells creation (manual or automatic stiching of small surfaces
          in bigger ones before meshing).

          Have a look on Capvidia and ProSTEP tools

              Hi Valery,
              thank you to respond to my question, but the external designer has MACH1 license, and FEMAP is not present.
              He uses NX5 and anyway he never used FEM solution.
              In our internal analyst department we have Simulation, but on imported geometry we always have problem., I thought that on SW 2009 Simulation we could do something.

              Thanks again,

              My experience with featureworks with stripping off filets from parasolid imported files was quite good. It wasn't exactly quick, a couple hours on previous generation laptop hardware of more than a couple of years ago. I had featureworks strip off north of 350 fillets off an investment casting model for a areo/defense VME card cage. You might want to revisit that one. I found it worked pretty nicely.
