The flux becomes instable almost instantly. The problem is with pression, I think. Because the result shows values of 1e14 for the pressure...

With the 1. and 2. corrections, the problem reaches the convergence almost instantly and I can post-processing the results. But I don't really know if they're correct or not :confused:

Replies: 15 PimpleFoam: High Courant and Instability Problem Views: 2,672 Posted By agiubilei PimpleFoam: High Courant and Instability Problem Good morning, I'm trying to study the porosity problem with OpenFoam because I have to simulate the porosity in a real geometry of thoracic aorta. So, I've started with a circular cylinder made...
