[dramesh]

Hello all,

I have a geometry that I split into 5 different regions. I created a hexahedral mesh in Ansys Meshing for each of these parts, then used the OpenFOAM mergeMesh utility to stitch the mesh together into one body. This merged body looks good except for one issue: the difference in mesh size between one region and another is too large at certain interfaces. I would like to ensure a size ratio of ~10% between neighboring cells. Is there a way I can achieve this using snappyHexMesh or a different meshing tool without risking the creation of non-hexahedral elements (my mesh needs to be purely hex)?

Thank you!
