Function Documentation

int callocate_arrays_global	(	int	x,
		int	y,
		int	z
	)

The main hydro arrays allocation routine. Here density, pressure, velocities and the computational domain arrays are dynamically allocated. The size is determined from the resolution parameters x,y and z in the specified parameter file.
