ORGANIZE_ActivateBNDpoints_Version
version for the boundary point activation
First of all, for better understanding of the activation algorithm, see
Illustration.
Default:
ORGANIZE_ActivateBNDpoints_Version = 3 (additional options see
FurtherOptions)
Option selection for version 3:
This version, in general, places ghost points at a small distance from free surface points in their normal direction, i.e. \( \mathbf{x}_\text{ghost} = \mathbf{x}_\text{FS} + \epsilon h \cdot \mathbf{n}_\text{FS}\). These ghost points are considered as interior points.
ORGANIZE_ActivateBNDpoints_Version | Description |
---|
30 | Measure the volume angle spanned by the local tetrahedralization; ignore tetras touching only free surface or boundary points (including the ghost points); deactivate a boundary point, if the volume angle is too small. |
31 (experimental, do not use) | Same as version 30; additionally, a boundary point is deactivated, if the local tetrahedralization forms open faces touching free surface points or their ghosts. |
32 (default) | Same as version 30; additionally, ignore any tetra touching some free surface point or its sidewise ghost. |
33 | Activate a boundary point, if its local tetrahedralization touches at least one interior point. |
34 | Activate a boundary point, if there is a path to some interior point that does not intersect with a disc spanned by either free surface of regular wall points (radius of the disc: \( r_\text{disc} = 0.4*h\)). |
9 | do not run the activation procedure, instead keep the currect activation status DEBUG option, handle with care!!! |
