Subrat@cgpl New Member Subrat Join Date: Mar 2016 Posts: 4 Rep Power: 10	Hello, I want to move surface nodes perpendicular to the neighbouring surface in a tetra mesh, could you please suggest how to do it using fluent UDF. And is there a way to find the average normal direction of the neighbouring surfaces of a node. Thanks in advance. Regards Subrat
