some troubles with "USER_GET_GVAR"

Hi, 1. I'm trying to use Junction box routine to get pressure on some boundary "wallname". But it fails, CALL USER_GET_GVAR('Air Ideal Gas.Pressure','wallname','areaAve', CRESLT,return_Pressure_Value, CZ,DZ,IZ,LZ,RZ), but if I change "Pressure" to be "Density" or "Temperature", then it's OK to get values, why?
2. How can I use USER_GET_GVAR function to get force in x-direction and y-direction seperately? Thanks for your help in advance. |

1 Different variables are stored at different locations e.g. nodes, integration points etc. This may be the problem.
2 The forces are given to you as a 3 component vector you have to extract the components of interest to you. |

Dear Ardisia,
The variable pressure is not a phase specific variable; therefore, it should not be prefixed with the fluid name. Try using CALL USER_GET_GVAR('Pressure','wallname','areaAve', CRESLT,return_Pressure_Value, CZ,DZ,IZ,LZ,RZ) instead This is documented in the USER_GETVAR section, and it should apply for USER_GET_GVAR.. Opaque.. |

opaque, it works, Use "Pressure" instead of "Air Ideal Gas.Pressure" is OK now!!
Thanks very much.... Ardisia |
