Summary0004175: wallHeatFlux-function object crashes when used on nonConformalMappedWall
DescriptionwallHeatFlux-function object crashes the simulation when used on a nonConformalMappedWall-patch connecting 2 regions. This seems to happen when the connection between the patches is broken due to relative motion.
Steps To ReproduceApply wallHeatFlux-FO on tutorials/multiRegion/CHT/engine2Valve2D-case on a valve, the simulation will crash on valve opening.
Example FO:

heatFlux_to_EV
{
  type wallHeatFlux;
  libs ("libfieldFunctionObjects.so");
  region exhaustValve;
  patches ( cylinderHeadValve1_on_nonCoupleExhaustValve );
  objects ();

  executeControl 1;
  executeInterval 1;

  writeControl 1;
  writeInterval 1;
}

It's just a divide by zero error caused by the patch having no faces and hence zero area after the valve opening. Fixed here:
