Hi @kkanade, here are the images.https://us.v-cdn.net/6032193/uploads/FW38N3I5XY10/f3.pnghttps://us.v-cdn.net/6032193/uploads/E1M4DD565FBW/f2.pnghttps://us.v-cdn.net/6032193/uploads/V1GIJV5MJK04/f1.pngMultiZone works fine but when Inflation is added I get message : "A software execution error occurred inside the mesher. The process suffered an unhandled exception or ran out of usable memory." I think the memory is not a problem. When I reduce first layer height from 1.9e-5 to 8e-4, mesh is executed successfully. But then my y+ is not 1 or smaller.https://us.v-cdn.net/6032193/uploads/DJMMR2N33CLF/mesh.pngI didn't use any further local settings and at one point when refining global settings again the same message appears.https://forum.ansys.com/discussion/comment/105953#Comment_105953

Hello, nBased on error message you provide - this seems like a memory issue. How many cells are we talking about in your mesh. Please check the mesh statistics for this number.nAlso, what is your Memory on this machine?nKarthikn
