I have written a passive scalar equation that should be used in a compressible solver like rhoCentralFoam but in each test case i use that the passive scalar (gas) itself and also its residuals increases during the run.
i thought its because of included rho but don't know how to remove rho from the equation because at least phi includes rho in it and the code doesn't accept dividing by rho.
how to overcome the situation of issue?
