Hello,
I'm having a hard time getting this model to work. The part is a ratchet and the analysis is fairly simple: model a rigid pin engaging in the ratchet and check for failure.
I created the geometry in UG NX and exported as a stp file for meshing in Gmsh. The Gmsh mesh was then imported to PreView. I created a pin and tried to move the pin into the ratchet.
I encountered multiple problems:
1) Importing Gmsh:

I encountered multiple problems:
1) Importing Gmsh:
i) The default extension is wrong, should be .msh, not .gmsh
ii) I get an error with the mesh version, resolved by deleting the mesh version specification at the top of the file.
2) Creating the FEBio file: The version that I have uploaded gives the errorii) I get an error with the mesh version, resolved by deleting the mesh version specification at the top of the file.
Couldn't save project to FEBio file:
Invalid reference to mesh item list.
3) When I did get a successful exportation on another mesh (reason this one works is unknown), executing the file gives the error from FEBio (file attached too):Invalid reference to mesh item list.
FATAL ERROR: Missing attribute "id" of tag "contact" (line 29526)
What am I doing wrong?
