I have a FLUENT case of pipe flow. 'X' is the axial direction. I want to plot the vorticity contours in r and \theta plane. How to convert x y and z vorticity to z,theta and r vorticity componenets
I prefer to export the FLUENT results to TECH PLOT 360 program and get an interest drawing about the vorticity in x,y, and z direction after adding its calculates.
Or display the results in CFD-POST by adding new plane then add new contour and select the vorticity in any direction.
Good luck
Just consider the equivalence of the vector expressions in the two reference system:
i vor_x + j vor_y + k vor_z = ir vor_r + i_theta vor_tet + k vor_z
so that you get, for example vor_r, by projecting the expressions along ir.
