Hi all,

I've been meshing some blocks with 6 solids in the domain (3 cubes, 1 cuboid, floor, ceiling) and been running some CFD and had noticed after computation, the contour results are not smooth transition been sections of the mesh as attached which I also believe is related to the flat iso-surfaces along each refinement region.

The y+ for each region is around 5, turbulence model is k-omega sst so the wall distance is very small. The mesh was generated using Pointwise.

Is there anyway I could resolve this, whilst keeping the mesh y-plus consistent around the solid boundaries?
