Hello,
I study on some analyses for my thesis. When I used first order, they were converged. But when I used second order, I have convergence problem. I tried different ways, I decreased under relaxation factors, Firstly, I used first order and then I continued with second order. But I couldn't solve this problem. I want to ask that are first order solutions acceptable? My mesh is tetrahedral. The flow is laminar. Also, I study on a combustion simulation. I have convergence problem. How can I solve this problem? |
