  I am running a 2D calculation in Fluent 2021 R1 (Windows GUI), after a while I get this message below. We have not found a way to adjust heap size for Windows as suggested in the error.
  
  Error: Out of Scheme heap space.
  Rerun with -h flag set greater than (multiples of 100000) current value of -h100000.
  Error encountered in critical code section
  The fl process could not be started.
