Dear kkanade I switched to Workbench CFX type mesher and applied patch dependant tetrahedrons method. The following attached images show the quality metric as SKEWNESS of the mesh. Without prism layers or inflation layers around the blades, skewness value is good with the applied parameters of mesh. But on applying the inflation around blade surfaces, it reduces the quality of mesh and the prism layers are not good adound the blades too. Please help on this. What type of inflation do I use around these blades like first layer height or total height or smooth propagation etc.
