I am a new user on OpenFoam. I would like to run a compressible, multiphase (molten metal and air) case with compressibleInterFoam. I use “perfectFluid” for the molten metal and I have a question about the specific gas constant R. The significance of this value has already been discussed in the thread compressibleInterFoam : biphasic, compressible, equation of state .
Why is the gas constant in the tutorials for water 3000? I don´t know whether the value was calculated or just selected.

Dear Niklas
Its easy to run that case, but the gas constant value given in tutorial is not correct. So kindly check all the values before you run your case.
