Hi Colin and Hannes

Thanks for yours replies. I meshing with new dimension for blockMesh with different mesh density and the problem of incoming wave was solved. Now I try to add a layer but for...

Hi Collin

So I change some values (turbulente intensity, turbulente length scale...) and I use a KomegaSST like turbulente model.

I modifie my mesh, now I have 2.6M of cells.

I run the...

Hi Colin

Thanks for yours indications.

I use 0.001 for I (I'm going to test with 0.005)

Mu turbulent lenght scale is 1 Lpp (I assume it's too hight)

My Cmu is 0.09

I use a simple...

Hi all

I found the solution. It seem I must create an box in SHM around the free surface to have a size different than 0 whit topoSetDict.

But now, when I use refineMeshDict, even if in...
