I'm not sure what is going on with my installation of Mechanica, but it absolutely refuses to use a saved mesh for an FEA. I have 8 loading conditions I have to check on a model that takes approximately 30 minutes to mesh. Every time I run an analysis it recreates the mesh and causes unecessary wait time. Is there some sort of options I am missing or what?
Try unchecking Override Defaults in the dialog box above.
Was autogem able to create the mesh without any error messages or warnings when you manually created the mesh? If not you will need to address those issues first other wise it will continully try to fix them each time it runs the analysis.
Together with your results issue (it doesn't want to vcxomplete that, it looks like you are very close to having to make your simulation model again.
