◆ computeTimeStepSize()

double Opm::SimpleIterationCountTimeStepControl::computeTimeStepSize ( const double dt,
const int iterations,
const RelativeChangeInterface & ,
const double  ) const
virtual

compute new time step size suggestions based on the PID controller

Parameters
dttime step size used in the current step
iterationsnumber of iterations used (linear/nonlinear)
timeErrorobject to compute || u^n+1 - u^n || / || u^n+1 ||
Returns
suggested time step size for the next step
