Reply To: Ansys crashed while executing a coupled CFD-DEM simulation

[kiran.purushothamakeshavan]

 

Here is another detailed excrept from the .trn file

If the solver was aborted, why does the .trn say that the solution converged?
Are  you refering to the error-files?
If yes then there is nothing above that error messege in the .txt file
