Questions about Cross-WLF viscosity model in interHeatFoam
Is there anybody using the Cross-WLF viscosity model in OpenFOAM? I want to investigate the polymer melt flow behavier in injection molding process. The Cross-WLF viscosity model can be described as follows:
I have added this model to OF-1.5-dev. When running interHeatFoam (adding T.Eqn to interFoam) solver with the Cross-WLF viscosity model, the courant number increased enormously after a few steps.Then the calculation stopped.
Any advice from anyone will be appreciated.
I am also struggling with the interHeaFoam, but not the Cross-WLF viscosity model. It is a difficult time.
Good luck to you.
