Solver Error and Crash
 
I have been running many transient simulations without any issue but recently I have been getting the below errors after 1 iteration.

A pop-up states: An unhandled win32 exception occurred.

and within the solver window the error is:

An error has occurred in cfx5solve: The ANSYS CFX solver exited with return code 1. No results file
has been created.


Does anyone know what this means and how it can be fixed? Steady-state simulations seem to run fine.


Thanks,


Brady

EDIT: I have been playing around with this problem and I thought I had it solved by increasing the timestep value. The solver runs for a while and then the error appears again. I am completely confused since I don't believe anything has changed since the last time it worked all the way to the end.
