Steady flow over a plan

Post by zihenwuming »

Hello everyone,

I'm trying to simulate a steady flow over a smooth solid plan with k-w SST, the inlet is u=y^(1/7) when y<1; else u=1; v=w=0, upper boundary condition is sliding smooth wall with u=1, v=w=0 to make a farfield, rou =1 kg/m3, p=101325 Pa, miu=3.33e-5, k=0.000833, omega=0.1318, but the result never goes well. I've changed the boundary conditions and other parameters, and tried several meshes, however, the result didn't turn better. Would someone could help me to examine if there is something wrong in the settings ? The mesh files are also attached as below. Thank you very much.

Best regards,

Wei

Hello,

Could you also mention what sort of problems you have (unexpected results, crash, ...) ?

This problem has been done. Thank you. It's because I set 'write at each step' in the result of 'write' in the 'out put control'. I have to set it as 'no periodic output' and 'output at the end of calculation'. Thank you.
But I met another problem. I put it as another topic. Thank you very much.
