January 28, 2013, 11:33	WSS Gradients	#1
prikeyma New Member Keyma Join Date: Aug 2010 Posts: 16 Rep Power: 15	Hello, I would like to calculate the WSS gradients in a curved pipe geometry using the CEL expressions in CFX-Post. Since I am using a curved pipe geometry I cannot compute the derivative using the global coordinate system. I need to define a local coordinate system and compute the derivative based on the local coordinate system. Does anyone know if it is possible to compute spatial derivatives in CFX based on a local coordinate system (i.e. not the global coordinate system)?
