[Description:]
|
|
|
|
This "forceModel" does not influence the particles or the simulation - it is a
|
|
postprocessing tool! Starting at start time the volume weighted averages of
|
|
those cells of the fields within the threshold are calculated.
|
|
|
|
At "writeTime" a field named volAverage_field, where scalarField is the name of
|
|
the original field, is written. This can then be probed using standard function
|
|
object probes.
|
|
|
|
[Restrictions:]
|
|
|
|
Currently all fields have the same threshold value!
