    Uni-Axial Tension Sim. Failed

      The part in question is thin rectangular plate with a hole through its center. An outward-acting force (tension) is applied to one of the faces, and the opposite face is fixed. However when I mesh and run the simulation SW is unable to complete the simulation. Solid Edge can perform this with this simulation tools. Any ideas how I can get this loading scenario to work with SW? A picture of the simulation set-up is attached.

      Thanks in advance

          There can be several reasons behind it. Are you trying to use SimulationXpress or SimulationWorks. Can you upload the part (with boundary conditions set) here to check.

           

          I did a quick test using SW SimulationXpress and it worked fine.

            This is definetely a simple analysis to run that Simulation should have no problem with.  Are you getting any error messages?  Is it meshing and then failing?  A little more info would help solve this.

              I did just uncover a bug in SW 2010 Simulation, that is fixed in SP5 (which is not available yet). The FFEPlus solver will fail without apparent reason, but it only happens on "some" Windows 7 machines. The cure at the moment is to switch to the Direct Sparse Solver. Also, make sure you have issued save command locally (as opposed to working on a file over the network), because Simulation needs to write data to a temporary location. Working off network, some people get a failure message because the solver is trying to write data to a location that the user does not have permission to write. I hope this helps. It has worked so far for all cases we've encountered. -Tony

                  I have also encountered this problem and am glad to hear they are fixing it.  I have found that when the FFE solver fails if I close the file and then reopen it using SW instead of opening it through Windows Explorer (we use PDM so I am just in the habit of doing it this way) it will almost always then run the analysis using FFE.
