Function Documentation

MMG5_chkmovmesh()

MMG5_int MMG5_chkmovmesh	(	MMG5_pMesh	mesh,
		MMG5_pSol	disp,
		short	t,
		MMG5_int *	tetIdx
	)

Parameters

mesh	pointer toward the mesh structure
disp	pointer toward the displacement structure.
t	fraction of displacement to test
tetIdx	to fill with the list of non valid tetra if provided.

Returns

0 if success (movement can be achieved), 1 or the number of invalid tetra otherwise.

Check if moving mesh with disp for a fraction t yields a valid mesh.
