  3. I set up a monitoring point for some variables in the CFX solver. However, when I evaluate the values of those variables in CFD-Post at the same coordinates, I get different values for my variables than those given in the solver manager monitor plot. Why is that?

      When setting up a monitoring point, the solver uses the vertex closest to the monitoring point coordinates that you have defined, and monitors the values using that vertex. Depending on the mesh resolution, the actual monitoring point may be a small distance away from the point you have specified. Information on the specified monitor coordinates, the actual vertex coordinates used, and the distance from the specified coordinates to the vertex are shown in the out file in the Solver section under “User Defined Monitor Information”. CFD-Post, on the other hand, will interpolate the values to the exact location that you specify. Therefore, the values from Post will differ slightly from that given by the solver at your monitoring point.
