function [UserVar,isStop]=DefineRunStopCriterion(UserVar,RunInfo,CtrlVar,MUA,BCs,F)

DefineRunStopCriterion.m

If the field

CtrlVar.UseUserDefinedRunStopCriterion

is set to true in

Ua2D_InitialUserInput.m

then the m-file

DefineRunStopCriterion.m

can be used to specify a run-stop criterion. Make sure this m-file is in your local run directory.

The criterion is used within the run-step loop, ie in both time dependent and time independent runs.

Note that this criterion is not used in an inverse run and has therefore no effect on if and when an inverse run stops.

isStop=false;

Example of a run-stop criterion based on norm of dh/dt.

RSC=norm(F.dhdt)/sqrt(numel(F.dhdt));
fprintf(' norm(F.dhdt)/sqrt(numel(F.dhdt)) = %f \n ',RSC)

if RSC==0 || isempty(RSC)  % If this is exactly zero, then dhdt has presumably not been calculated
  isStop=false;
else
  if RSC < 10
      isStop=true;
  end
end

end
