Excuse me!
Since the function "USER_GATVAR" is not relevant to junction box routines, could it be called in Particle User Routine? I want to call USER_GATVAR to get curls in Air with Particle Tracking, but always failed.
I have test the code
"CALL USER_GETVAR ('Air|Red Sand.Air.Velocity.Curl', CRESLT, pCURL_VELFL, CZ, DZ, IZ, LZ, RZ)
and
"CALL USER_GETVAR ('Air.Velocity.Curl', CRESLT, pCURL_VELFL, CZ, DZ, IZ, LZ, RZ)
but none of these works.

Thanks for your consideration!
