		char *	argv[]
	)

---------------------------— STEP I -----------------------—

1) Initialisation of mesh and sol structures

2) Build mesh in MMG5 format

Two solutions: just use the MMG3D_loadMesh function that will read a .mesh(b) file formatted or manually set your mesh using the MMG3D_Set* functions

Manually set of the mesh

a) give the size of the mesh: 12 vertices, 12 tetra,0 prisms, 20 triangles, 0 quads, 0 edges

b) give the vertices: for each vertex, give the coordinates, the reference and the position in mesh of the vertex

c) give the tetrahedras: for each tetrahedra, give the vertices index, the reference and the position of the tetra

d) give the triangles (not mandatory): for each triangle, give the vertices index, the reference and the position of the triangle

3) Build sol in MMG5 format

Two solutions: just use the MMG3D_loadSol function that will read a .sol(b) file formatted or manually set your sol using the MMG3D_Set* functions

Manually set of the sol

a) give info for the sol structure: sol applied on vertex entities, number of vertices=12, the sol is scalar

b) give solutions values and positions

4) (not mandatory): check if the number of given entities match with mesh size

---------------------------— STEP II -----------------------—

remesh function

---------------------------— STEP III -----------------------—

get results

Two solutions: just use the MMG3D_saveMesh/MMG3D_saveSol functions that will write .mesh(b)/.sol formatted files or manually get your mesh/sol using the MMG3D_getMesh/MMG3D_getSol functions

1) Manually get the mesh

a) get the size of the mesh: vertices, tetra, triangles, edges

b) Vertex recovering

d) Triangles recovering

e) Edges recovering

c) Tetra recovering

2) Manually get the solution

a) get the size of the sol: type of entity (SolAtVertices,...), number of sol, type of solution (scalar, tensor...)

b) Vertex recovering

3) Free the MMG3D5 structures
