Hi Foamers,

I'm trying to create a new solver related to the mixture model. I use OF version 19-10 for Windows. For the custom solver(s) I modified both interFoam(pimpleFoam) so that I could introduce the necessary variables etc. The solver(s) compile without any errors however when I try to set up 2d cases of straight channel and dambreak. I get the same error for both the solvers. I'd attached the screenshot of the errors.
I have put certain flags in the solver to debug, from this knowledge I understand that the solvers is erroneous when solving the Ueq = -grad(p) part. The initial and final residuals are naN right from t=0. Please see the attached picture for the error message. Please help.
