CFX Solver Stops the Running
 
Hi all

I am doing unsteady simulation with Ansys CFX. Total simulation time is 3s and all data is saved at each time step. Sometimes, CFX solver stops running and quits in the middle of the simulation (for example at t=1.5s). Does anybody know how I can continue the simulation from where it is stopped (from t=1.5s)?

Thank you
Regards,
AshtonJ

It is called a restart. Use the most recently saved transient results file as an initial condition. Pretty elementary really.

They only trick is the results file needs to contain enough information to do a restart. You will need a transient results file which includes mesh and enough variables to reproduce the flow to be useable.
