time_step_controller_set_dt()

subroutine time_step_controller::time_step_controller_set_dt ( class(time_step_controller_t), intent(inout)  this, real(kind=rp), intent(inout)  dt, real(kind=rp), intent(in)  cfl, real(kind=rp), intent(inout)  cfl_avrg, integer, intent(in)  tstep  )

private

Parameters

dt	time step in case_t.
cfl	courant number of current iteration.
cfl_avrg	average Courant number.
tstep	the current time step. @Algorithm: Set the first time step such that cfl is the set one; During time-stepping, adjust dt when cfl_avrg is offset by 20%.
