hi everyone! I am new to OpenFOAM and now I am doing sth with the solver: compressibleInterFoam.
the solver don't output rho automatically so I change the IOobject of rho in creatFields.H to MUST_WRITE.
everything go fine and it output rho every timestep.
BUT the problem is that it does not output at time 0
I know 0 is like a dictionary which is set manually but I think rho is a number which could be calculated,
So,I should I change my file???
