I have an interesting problem with simulation that just happened today...

Earlier i started a study, was able to define and create the mesh just fine, ran the simulation with h-adaptive meshing and got an answer. I then modified the geometry, tried to re-mesh and it would not complete... I looked at the failure diag, it said surface mesh completed, volume mesh failed... no matter what i did (reducing element size as small as it would go) the mesh always failed.

I then tried a test to see if it was my geometry or not. I created a simple part, 1x2x3in and tried to create a mesh, if anything this should mesh!!! STILL the mesh fails, same error (surface mesh completed, volume mesh failed). I tried removing the SRAC folder from the registry, and also the SolidWorks folder, still nothing... Tried uninstalling simulation, and re-installing, still does not work on a new 1x2x3in part. WHAT GIVES???!!! The only mesh that WILL work is SHELL mesh, and BEAM mesh... What am i missing? I don't get it...

Any suggestions would be appreciated.
