Dear Foamers,
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: 01.png 03.png 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. Kind regards, Jitao |

I am also struggling with the interHeaFoam, but not the Cross-WLF viscosity model. It is a difficult time.
Good luck to you. chiven |
