MV78 New Member Join Date: May 2018 Posts: 8 Rep Power: 7	Hi, I am using hypermesh to create a very simple mesh for a 2D axisymetric shell-and-tube heat exchanger. I need to refine my mesh in the viscous sublayer of the heat transfer fluid. I merely did that with quads and the biasing option. However, I don't understand how but the biasing introduces some skewness and reduces the mesh quality. Thus, it prevents the simulation of the turbulent flow from converging correctly contrary to a regular mesh without biasing. Is it normal ? Thank you in advance ! MV78
