hello,
i am new to cfd.
can someone help me? is this proper mesh? or should i change something?
thx a lot for help.

Although it looks good, it depends on what you want to simulate.

hello, i try to simulate swirl velocity. I made measurements on real models. now i am trying to simulate this.

Most of your wedge elements (the ones in the boundary layer) seem to be of low quality. You can try to improve by playing with mesh size.

Also you can run a test example with your mesh. If the 'viscosity limited' error persists then you may have to further refine your mesh. Remember the 'viscosity limited' error is ok/tolerable in the beginning of the simulation (say first few time steps or iterations) but not later than that.

i still get problems with this profile. i try different kind of mesh, but always simulation results are incorrect.
can you look on my profile i give me some advice?
