Dear Foamers,
I want to perform a compressible VOF simulation of water and gas within a mixer. Starting from the mixerVesselAMI tutoriel, initialy given for interFoam (incompressible case), I updated the case for compressibleInterFoam. However, the simulation crashes at initialization, just after selecting the thermodynamics package of my gas, with a segmentation fault. Interestingly, I have seen that: 1. If I use a constant density for the equation of state, it works! It's only with perfect gas or other EOS that it crashes. 2. If I run a steady MRF computation without cyclic AMI condition at the interface between the rotor and stator zones, it works too! So I have the feeling that something's missing for the computation of thermodynamic variables in case of rotating grids. Has anyone experienced something like that ? Regards, Mat |
