Issue with patching in multiphase

  I am using VoF in multiphase model and using 3 Eulerian phases, air and two metals. I initialized air through UDF and patching spherical metal particles using a journal file. The metals are different. When I read the journal file, there is a warning message:
  Warning!! The sum of phase volume fractions exceeds 1 in some cell(s).
  This can lead to potentially erroneous initialization. Please insure that the sum of phase
  volume fractions in a cell does not exceed 1 during intitialization or patching!!
  
  Can someone please tell what is the issue? After a certain time the patching stops.

  I've seen that a few times. If you initialise to all primary phase, then patch each secondary in turn it ought to work. Also watch the packing limit if you're using granular.
