Basically, you need the sides to be periodic, and if you continue these across the model, you will get high skewness... SO we add one quarter ogrid on one side and another opposite one on the other side so we can shift the index between the two sides... In other words, if you follow the edge from one periodic side, it doesn't go right to its periodic twin. Instead, it is shifted... But in such a way that the whole model is still periodic... __________________ ----------------------------------------- Please help guide development at ANSYS by filling in these surveys Public ANSYS ICEM CFD Users Survey This second one is more general (Gambit, TGrid and ANSYS Meshing users welcome)...
