Function Documentation

MMG2D_mmg2dlib()

int MMG2D_mmg2dlib	(	MMG5_pMesh	mesh,
		MMG5_pSol	sol
	)

Main "program" for the mesh adaptation library.

Parameters

mesh	pointer to the mesh structure.
sol	pointer to a sol structure (metric).

Returns

MMG5_SUCCESS if successful, MMG5_LOWFAILURE in case there is a failure but a conform mesh is returned and MMG5_STRONGFAILURE if there is a failure and we can't save the mesh.

This function adapts a given mesh, trying to improve the quality, under the given metric and parameters.

Remarks

Fortran interface:

‍ SUBROUTINE MMG2D_MMG2DLIB(mesh,sol,retval)
MMG5_DATA_PTR_T, INTENT(INOUT) :: mesh,sol
INTEGER, INTENT(OUT) :: retval
END SUBROUTINE

MMG2D_mmg2dls()

int MMG2D_mmg2dls	(	MMG5_pMesh	mesh,
		MMG5_pSol	sol,
		MMG5_pSol	met
	)

Main "program" for the level-set discretization library.

Parameters

mesh	pointer to the mesh structure.
sol	pointer to a sol structure (level-set function).
met	pointer to a sol structure (metric).

Returns

MMG5_SUCCESS if successful, MMG5_LOWFAILURE if there is a failure but a conform mesh is saved and MMG5_STRONGFAILURE if there is a failure and we can't save the mesh.

This is the main program for the level-set discretization library. If a metric met is provided, it is used to adapt the mesh.

MMG2D_mmg2dmesh()

int MMG2D_mmg2dmesh	(	MMG5_pMesh	mesh,
		MMG5_pSol	sol
	)

Main "program" for the mesh generation library.

Parameters

mesh	pointer to the mesh structure.
sol	pointer to a sol structure (metric).

Returns

MMG5_SUCCESS if successful, MMG5_LOWFAILURE if there is a failure but a conform mesh is returned and MMG5_STRONGFAILURE if there is a failure and we can't save the mesh.

FIXME: This function creates a triangular mesh from a given polygon, right?

	)

Main "program" for the rigid-body movement library.

Parameters

mesh	pointer to the mesh structure.
sol	pointer to a sol structure (displacement).
disp	pointer to a sol (displacement for the lagrangian motion mode) structure.

Returns

MMG5_SUCCESS if success, MMG5_LOWFAILURE if there is a failure but a conform mesh is saved and MMG5_STRONGFAILURE if there is a failure and we can't save the mesh.

Remarks

MMG2D_restart()

static int MMG2D_restart ( MMG5_pMesh  mesh )

inlinestatic

Parameters

mesh	pointer to the mesh structure.

Returns

0 if fail (lack of memory), 1 otherwise.

Clean the mesh structure when we just call the MMG2D_Free_Triangles and MMG2D_Free_Edges functions between 2 call of the MMG2D_mmg2dmesh function:

• Allocate the tria and edge structures if needed;
• Reset the tags at vertices.

If needed, reallocate the missing structures
