Hi!

I made a mesh in Fluent Meshing and now I would like to know if there is a way to refine that mesh linearly? In other words, my mesh has a variaty of cell sizes and I would like to keep it that way. So my quastion is: is there a way to change the WHOLE mesh with the same scale factor for every cell and not just do some refinement in specific areas? I´m attempting to do a Richardson Extrapolation.

Best regards, Johanna

You can adapt (refine) the whole mesh. Note, that won't quite retain the cell size ratios as hex, tet, poly and prism cells split slightly differently. You may also find the new cell count is significantly larger that it was before and that may present you with resource issues: you may need more parallel licences and hardware.

I am assuming that it is this you are refering to? Do you know what there are no reggions for me to choose?
