Driver_computeDt()

subroutine Driver_computeDt	(	integer	nbegin,
		integer	nstep,
		real	simTime,
		real	dtOld,
		real	dtNew
	)

Determine the stability-limited time step. This timestep is determined using information from the included physics modules - many different timestep limiters are polled.

The global driver might use a different (hopefully smaller) time step, to match a file write time (tplot or trstr) or if the simulation end time has been reached; such possibilities are not considered here.

nbegin - first step of the simulation (this is only used to determine if a label header should be written to the screen) nstep - current step of the simulation simTime - current simulation time of the run dtOld - the dt from the timestep that we just finished (it's old because we be using dtOld to calculate and return the dt for the next timestep (dtNew) dtNew - returned value of the dt calculated for the next timestep
