 January 24, 2005, 00:46 Could vorticity magnitude be ploted ? #1 w0er Guest   Posts: n/a wx = dw/dy - dv/dz wy = du/dz - dw/dx wz = dv/dx - du/dy w = wx(i) + wy(j) + wz(k) vorticity magnitude = sqrt(w.w) = sqrt( wx*wx +wy*wy +wz*wz but how could i define the function into CFD post template?eg:CFX5-POST,FIELD-ViEW,CFD-View

 February 8, 2005, 08:49 Re: Could vorticity magnitude be ploted ? #5 CFD-junior Guest   Posts: n/a Hi The variable doesn't work. I've tried that. I'm trying to create helical density which is the dot product of the velocity vector and vorticity. could someone please help. I want to know how to enter it in the expression block in CFD-View
