I'm working on a problem where I want to set the heat flux at a boundary based on the temperature at a specific point. I'm trying to simulate thermostatic control of a heater.
I generated a point surface using Surface>Point...
It shows up as a surface group with an id and name, but this is not a ZONE_ID.

I can create an output parameter (area averaged temperature) with Define>Parameters... but when I tried to access this with a Scheme macro (RP_Get_Value("parameter_name")) in the UDF, it failed.
How can I look up this temperature from within the UDF???

I would really appreciate any help anyone can give on this. Thanks!

Try to use:
RP_Get_Real("variable-name")
