  1. grbric_ID should be a group of an 8-nodes brick element.
  2. /IMPFLUX is not compatible with ALE applications (/ALE, /EULER). Imposed flux will not be applied to ALE nodes or ALE elements.
  3. When a sensor is defined sens_ID, the imposed thermal flux is applied at the time of sensor activation and the function is shifted by the sensor activation time.
  4. Volumic thermal surface flux (grbric_ID > 0) is compatible only with /PARITH/OFF.
  5. Only surf_ID or grbric_ID can be set, but not both.
