Question on Body int - savescalars

[Matrixrifle]

Hi,
Where can i find documentation on body int and which operations it can support. I observed that the following which calculates the surface integral of A (magnetic vector potential) works whereas the same when applied to current density does not work.. any ideas ?

body int applied to A

Code: Select all

Solver 6
   Exec Solver = After Timestep
   Procedure = "SaveData" "SaveScalars"
   Filename = res/f1.dat
  Variable 1 = A
  Operator 1 = "body int"
  Mask Name 1 = Stator_Winding
End

body int applied to J (current density) . For more information on the problem please refer to this post. (https://www.elmerfem.org/forum/viewtopic.php?t=8107)

Code: Select all

Solver 6
   Exec Solver = After Timestep
   Procedure = "SaveData" "SaveScalars"
   Filename = res/f1.dat
   Variable 1 = current density
   Mask Name 1 = "Terminal1"
   Operator 1 = body int
End
