ALE calculation suddenly stopping with no error
Posted: Wed Jun 12, 2019 11:26 am
Hello,
I am performing an ALE simulation. The simulation stops after a few iterations (much less than the ones specified), but no error is displayed in the listing nor in the other files.
In the listing, after the last iteration, the "Final stage of the calculation" and "End of calculation" messages appear.
The values of the mesh displacements and of the fluid variables are consistent, no divergence in these values is observed.
Looking at the mesh once the simulation has stopped, I do not see any negative volume cell or other problems in the mesh that could cause the simulation to stop.
The meshing is purely hexa (ICEM).
Do you have any idea about what to check in order to understand the cause of the end of the calculation?
Many thanks in advance.
Best regards,
Daniele
