Ansys CFX doesn’t register a change in parameter

  Hi,
  I want to test several different mass flow rates, so I created an expression and used it in the Outlet Mass Flow rate parameter.
  I then went to CFD-Post and selected the expression that gives me the actual measured mass flow rate after running the simulation.
  No matter what I do, Ansys simply ignores the value I give for the input parameter.

  Hi Jesse,
  I can see that MFlow has been defined, but for the mflowtotal, the expression you have used is mflow*nMainBlades. mflow has a lowercase 'm'. Whereas the original mass flow expression had Uppercase 'M'.
  This might be the problem.

  I think I found the problem, I reset the results (cfx-post) and now its working. It was using old equations that needed to be reset or re-calculated, even tho i dont see how the results should be affected by the post-processor.
  Anyway it's working now !
