GfsRemovePonds removes isolated "ponds" i.e. pockets of fluid surrounded by solid.
The syntax in parameter files is:
[ GfsEvent ] MAX
MAX is an integer which defines the maximum size of the ponds to be removed. If MAX is positive, all the ponds defined by less than
MAX cells will be removed. If
MAX is negative, all the ponds but the
-MAX largest ones will be removed.
Note that if your domain does not contain any embedded solids (defined using GfsSolid) it will not contain any "ponds".
