| 31 | cAA de ces trois champs sur les 4 subsurfaces du modele. Dans l'avenir |
|---|
| 32 | cAA si les informations des subsurfaces doivent etre prises en compte |
|---|
| 33 | cAA il faudra sortir ces memes champs en leur ajoutant une dimension, |
|---|
| 34 | cAA c'est a dire nbsrf (nbre de subsurface). |
