ANSYS CFX Return Code 1. But why??
 

Hello,

I have a steady simulation including two fluid domain and one porous domain. It has finished, converged.

Now, I would like to see this case without porous domain. I changed it to simple fluid domain. It was initialized from previous converged model but I always get this after start directly:

"The ANSYS CFX solver exited with return code 1."

What is the reason? Please help me.

Thanks
Roland

Its hard to guess what the issue is based off of the information given, but I have run into this problem before when running a simulation after changing a parameter. Try right clicking on "solution" and resetting the simulation, then proceed to run the simulation.

Thanks Lund, but I think, My problem is not the changing of this parameter because I tried to run the same simulation on other computer and it operated. I think, this is a general CFX notice which can include a lot of problems...
