◆ MMG5_boundingBox()
| int MMG5_boundingBox | ( | MMG5_pMesh | mesh | ) |
- Parameters
-
mesh pointer toward the mesh structure.
- Returns
- 1 if success, 0 if fail (computed bounding box too small).
Compute the mesh bounding box and fill the min, max and delta fields of the MMG5_info structure.

◆ MMG5_check_hminhmax()
| void MMG5_check_hminhmax | ( | MMG5_pMesh | mesh, |
| int8_t | sethmin, | ||
| int8_t | sethmax | ||
| ) |
- Parameters
-
mesh pointer toward the mesh structure. sethmin 1 if hmin is setted by the user. sethmax 1 if hmax is setted by the user.
Check the compatibility between the automatically computed hmin/hmax values and the user settings.

| MMG5_pSol | met, | ||
| MMG5_pSol | sol, | ||
| double * | dd, | ||
| int8_t * | sethmin, | ||
| int8_t * | sethmax | ||
| ) |
- Parameters
-
mesh pointer toward the mesh structure. met pointer toward a metric sol pointer toward a solution structure (level-set or displacement). dd pointer toward the scaling value (to fill) sethmin setted to 1 if hmin must not be computed from the metric. sethmax setted to 1 if hmax must not be computed from the metric.
- Returns
- 1 if success, 0 if fail.
Scale the mesh and the size informations between 0 and 1. Compute a default value for the hmin/hmax parameters if needed.

| int MMG5_scale_scalarMetric | ( | MMG5_pMesh | mesh, |
| MMG5_pSol | met, | ||
| double | dd, | ||
| int8_t | sethmin, | ||
| int8_t | sethmax | ||
| ) |
- Parameters
-
mesh pointer toward the mesh structure. met pointer toward the metric structure. dd scaling value. sethmin 1 if hmin must not be automatically computed sethmax 1 if hmin must not be automatically computed
- Returns
- 1 if success, 0 if fail.
Scale and truncate by hmin/hmax the scalar metric stored in met. If hmin/hmax are not provided by the user, it is automatically computed from the metric.

| ) |
- Parameters
-
mesh pointer toward the mesh structure. met pointer toward the metric structure. sol pointer toward a solution structure (level-set or displacement).
- Returns
- 1 if success, 0 if fail (computed bounding box too small or one af the anisotropic input metric is not valid).
Scale the mesh and the size informations between 0 and 1. Compute a default value for the hmin/hmax parameters if needed.

| ) |
- Parameters
-
mesh pointer toward the mesh structure. met pointer toward a metric. sol pointer toward a solution structure (level-set or displacement).
- Returns
- 1.
Unscale the mesh and the size informations to their initial sizes.
