  Hello
  I have to boundary .i have udf that determine the flux of mass.
  The boundaries have motion with grid motion.
  I want when the define profile of boundary 1 start check the coordinate of boundary 1 and 2. If the distance is equal to 1 cm set the flow 0 for that faces. Similar of that is for boundary 2. In code we can use only 1 boundary coordinate.
  Else i collect the coordinate with define adjust for 2 boundry and use f_udmi.
  But when define profile start the loop we can access only to boundary 1 coordinate. And fluent set the boundary 2 coordinate zero.
  Please help me.
  Best regard

  You can use anot ADJUST prepare everything and the condition is fulfilled you can then execute the profiles by passing some flags.
