Error in previously saved files after patching and starting calculation
I am working on a 2D transient model with energy and species transport. I first converged flow and turbulence in a steady state model. After that, I calculated a solution in a transient model for the energy equation and now I want to calculate the transient solution for species transport. However, I entered all of my settings for species transport, than saved the case and data file before patching and solving, because I know that things can go wrong in those steps.
Afterwards, I saved the case and data file under a new name and I patched the values I needed in this new file. During patching I got error messages saying the turbulent viscosity ratio was limited to 1e5 and when I start the solution I got an MPI error:
Thinking that I could start over from the case and data file that I saved before patching and solving, I opened this previous file. However, opening this file (which previously gave no problems) resulted in an error and I could not use this file anymore and had to start over.
I have had this problem multiple times and it is very time consuming to have to start over and over again, always entering the same settings, hoping it won’t result in an error that corrupts all of my files.
Can anyone help me deal with this problem? What is the reason for these errors and for the error in the original file before patching and can I prevent having to start over with entering the settings each time such an error occurs? I am pretty new to CFD, so making some mistakes is almost inevitable for me.
Thanks in advance for the help.
