ashtonJ Senior Member Ashkan Javadzadegan Join Date: Sep 2010 Posts: 255 Rep Power: 16	Dear all, I need to define an expression in CFX-Pre to calculate the spatial gradient of wall shear stress (WSSG): WSSG = SQRT((d(WSS)/dx)^2+(d(WSS)/dy)^2+(d(WSS)/dz)^2) I would be too pleased if any body can help me.
