I'm performing a study and I'm measuring pressure at a point. I've added a point goal to the edge of a circle which creates a point at its center, for convergence control and to monitor the values during the calculations.. Comparing the value from the goal to the value from a point parameter at the exact location yields me completely different values...

Point Goal: 14.4236PSI

Point Parameter: 13.943PSI

Am I missing something because from my understanding these values should be near identical... I've tried multiple runs with a denser mesh and very dense local mesh around the point I am measuring with similar results...

Hope you can help!

I have never used the point goal in all my years of using Flow which is approaching 20. I suspect the issue is that you are comparing total pressure to static pressure though from what was shown its hard to tell. No qualification is given in the point parameters on which pressure it is giving you but maybe that was in the selection list.

I have never used a point goal to instrument a model because all sensors have a finite volume. I put in a small volume typically when I instrument a model and use volume goals. These goals and volume parameters provide the same array of values for a given parameter like pressure - total, static and dynamic.
