Hi all,

I am simulating a case with a very large mesh (>40 million). I need to generate a coarse mesh first, and decompose it, and then refine the mesh using refineMesh.

Unfortunely, refineMesh just "refine" the mesh but it can not interpolate the initial value so I need to use refineHexMesh instead. But again, refineHexMesh will automatically refine the mesh in all x,y,z direction, which is not what I want.

In wall-normal direction (y), I need to control the mesh directly and I will specify the mesh distribution in the coarse mesh and I just want to refine in the x, and z direction. I can just refine in x,z direction using refineMesh (I can add some lines in refineMeshDict), but I can not do similar thing by using refineHexMesh.

So is there any way I can do it? I tried many ways but all failed...

Tons of thanks in advance!

Best regards,
