Hi all!


I am new to OpenFOAM so hopefully it's not a dumb question...
Recently I was using multiphaseEulerFoam to simulate a gas solid case. At first the case run well, and it converged successfully. However, when I copy the 0, constant and system folders to a new folders without changing any parameters, the new one just diverged. This problem happened to me a lot of times before. And now no matter how I change the parameters in the new folders, it just kept giving the same error message. Anyone knows why it happens?


Thanks in advance!!

Hi Hart,
I suggest you could try to reduce the time step in controlDict. Sometimes this happens when the time step is too large.
