Function Documentation

void mainloop	(	double	t_start,
		double	t_end
	)

Integrate in time the physical system from t_start to t_end. Outputs are done according to gvars.h

Parameters:

t_start,:	initial time of the simulation (usually 0...)
t_end,:	final time of the simulation (will stop precisely at that time).

Here is the caller graph for this function:

double newdt	(	struct Field	fldi,
		double	tremap
	)

generate a timestep (dt) as a function of the current flow configuration/velocity This routine is essentially an application of the CFL condition. it returns a timestep (dt)

Parameters:

tremap,:	when using shear, the current remap time of the frame
fldi,:	Field structure containing the flow status
