Function Documentation

int main	(	int	argc,
		char **	argv
	)

The main function of the step2 example program.

It creates a connectivity from an ABAQUS .inp file and forest, refines it, and writes a VTK file.

static int refine_fn	(	p4est_t *	p4est,
		p4est_topidx_t	which_tree,
		p4est_quadrant_t *	quadrant
	)		[static]

Callback function to decide on refinement.

Refinement and coarsening is controlled by callback functions. This function is called for every processor-local quadrant in order; its return value is understood as a boolean refinement flag.

Here we use uniform refinement. Note that this function is not suitable for recursive refinement and must be used in an iterative fashion.
