Changing inlet conditions without starting again
I've ran a simulation for about 24 hours and I'd like to now change the inlet velocity slightly.
Is there a way to copy the internal fields from the old case but use the inlet conditions from "0" in the new case? It would speed up the convergence considerably.
I've tried using mapFields but it seems to always use the inlet velocity from the old case, and none of the pyFoam tools seem to be suitable.
In Ansys CFX I could tell the solver to initialize from a results file but it would take all the boundary conditions from the new case, that's exactly what I'm trying to do here.
Thanks a lot, I was also having problems opening the results files but I changed the output format to ascii in controlDict, ran a couple more iterations, and now I can change the boundaryFields like you suggested.
