have performed a solidworks flow simulation on solar parabolic trough collector. I placed a metal pipe at the focus of parabolic reflector. After the simulation, I was trying to extract the net radiation flux ( solar) on the surface of the pipe at the focus of parabolic trough. But when I tried to export the result to a text file, I was getting 5 columns. 1) x coordinate, 2) y coordinate 3) z coordinate, 4) surface area (m2) 5) net radiation flux (solar) W/m2.
But the last column is empty.
Can you help me. Thank you.
