Elements are missing from exported mesh. (HyperMesh)

[pytunia]

• Check if HyperMesh was closed before all nodes and elements were processed. (This can take longer than expected for bigger models).
  Re-Export and observe message in lower left corner.
• Maybe the user profile was changed while working in the model and this messed up the definition of the elements.
  Try: 2D/3D --> element types --> 2D & 3D --> select all elements --> update
