**1. Where is the polyMesh placed after completion of SnappyHexMesh?**
**Ans:** Depending on the number of operations you have performed the polyMesh is placed inside time directories within working project area.
Directory 1 contains polyMesh after castellation
Directory 2 contains polyMesh after Snapping and
Directory 3 contains polyMesh after Layering operation.
**2. SnappyHexMesh is not able to generate mesh inside my refinement zone. Why?**
**Ans:** This can happen when you have created/imported refinement region and supplied surface refinement over the same.
If surface refinement is to be specified, you have to prepare a separate zone for the
same. If you do not intend to create an additional Fluid zone, it is recommended to use volumetric refinement.
**3. I have reduced size of base mesh; however the total cell count does not increase. I do not see adequate resolution, why?**
**Ans:** This is observed when the cell count limit is met in SnappyHexMesh. The log file should have this reported as: No cells marked for refinement since reached limit XYZ…, where XYZ denotes the maxGlobalcells specified.
You need to increase value of maxLocalcells and maxGlobalcells and rerun the mesh generation from scratch.
