Sir Let me explain.
I have a capillary tube with ID 0.2 mm. At inlet i give mass flux with liquid phase. At the exit of the capillary tube i define a region where i patch temperature. I am getting divergence error in pressure coupling etc.
My Solver setting as follow
I am simulating flow through porous medium with VOF method and species transport. For phase change i have Lee Model, and i have no idea about the evaporation frequency and condensation frequency
Second I am using the evaporation frequency as 30. The liquid is n-heptane while for vapour phase i...
