Tetra Mesh Optimization: Invalid input Mesh
Altair EmployeeHallo to all,
I have a problem I never experienced before. Perhaps some of you had this issue before.
I want to improve the element quality with tetra mesh optimization tool. My input settings are:
- 13 parts with its mesh
- Fix all
- Fix shell comp boundaries
- Maintain geometry edges
-Optimise tetras by force
Optimizer starts and after some time I get the error message: 'Invalid Input Mesh' in the left bottom corner of the Hypermesh screen.
When I change to Edge Swap or remesh this error occurs much faster.
I already checked If I have any duplicates, connectivity problem or other elements than Ctetras. But everything with that is OK. I have no clue why this error message appears.
Kind regards,
Daniel

Altair EmployeeYes I can share it. The components that didn´t work are: HDP_Lager, NWBruecke_Auslass and NWBruecke_Einlass. The others went pretty well.
Altair EmployeeHi,
This seems to be an issue with the elements in the NWBruecke_Einlass component. I recommend you to remesh this component and try the Tetra Mesh Optimization again.
Hi,
I tried with a simple model and it works fine.
Can you share the model so that we can try the same here.
