transient calculation
Sir ,
I am performing transient calculations over a body using su2. The flow mach number is changing from mach=0.3 to mach=3 .I am working with unstructured gird.As soon as the code reaches Mach =1 it become unstable.So far i have tried using different limiter coeff value ranging from 15 to 0.3 , reducing time step,grid refinement,JST model but problem is still there. can u please suggest me some way to overcome this problem.Thnxx |
