Hi,
I am currently doing a 3D simulation for an aircraft. model- k-w sst steady-state pressure based solution Mesh Quality: Minimum Orthogonal Quality = 1.17479e-04 cell 796080 on zone 2 (ID: 1405101 on partition: 1) at location (-1.39139e+01 2.22699e+00 8.14461e+01) Boundary conditions velocity inlet pressure outlet Solution method Coupled and second order for the rest. During the solution phase, I get huge spikes in the calculation for both lift and drag force. also, a message is posted " Stabilizing pressure coupled to enhance linear solver robustness." - don't know what it means. I have attached images. Any help would be appreciated. |
