Member Function Documentation

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:
dt time step size used in the current step
iterations number of iterations used (linear/nonlinear)
timeError object to compute || u^n+1 - u^n || / || u^n+1 ||
Returns:
suggested time step size for the next step
