Question

Simulation failed!

I've been trying to run a simulation on a frame and it keeps failing. It says in the log

AutoGEM has detected an element incompatibility across the

highlighted curve. Adding points to the curve may help.

In some cases, re-creating the curve and adjacent

surfaces may be required.

but I can't see anything highlighted.

In the log it also says:

The highlighted geometry may cause meshing problems.

Creo Simulate has placed this geometry in the group "agem_bad_geom".

All problematic geometry is automatically placed in this group.

I don't know where this file is. Any help would be greatly apreciated

    Try to create the mesh out of an analysis (AutoGEM>Create...).

    It is usually better to solve meshing problems.

    Well I have tried to use the model setup option then checking on the FEM mode for the mesh option to appear. I don't know where the AutoGEM>Create sequence you're talking about comes from.) When I try to use this mesh option I tend to get this error

    The highlighted face appears more than once in the

    surface mesh.

    and it is ussually some peice of a tubing where two pipes join mesh failure.pngI

    I have also been told there is a crack in the tubing?? before. I have no idea how to fix these issues...

      Well, I'm using WF5.

      In CREO2, it is located in Refine Model>AutoGEM.

      Or you can directly use the Refine Model>Diagnostics tool.

      I would increase the accuracy

      Best way is to change your config.pro

      Add: Enable_absolute_accuracy Yes

      Then set accuracy to a reasonable value of eg 0.01 mm

      The geometry will mesh easily!

      Well that kinda helps but I'm back to getting the crack error...crack%21.png

      Has anybody had any luck getting results with simulations on a frame?? This is starting to get frustrating haha
