8.2. remesh commandΒΆ
-
remesh
(alpha=-1.0) - \(\alpha \ge 0\) for updating moving mesh.
- \(\alpha < 0\) for updating background mesh.
If there are nodes shared by different mesh in the domain, the principles to decide what element should be used for a triangle:
- If all 3 nodes share the same mesh, use that mesh for the triangle.
- If all 3 nodes share more than one mesh, use the mesh with
eleArgs
defined and lowestid
. - If all 3 nodes are in different mesh, use the mesh with lowest
id
. - If the selected mesh
id
>= 0, skip the triangle. - If the selected mesh has no
eleArgs
, skip the triangle.
alpha
(float)Parameter for the \(\alpha\) method to construct a mesh from the node cloud of moving meshes. (optional)
- \(\alpha = 0\) : no elements are created
- large \(\alpha\) : all elements in the convex hull are created
- \(1.0 < \alpha < 2.0\) : usually gives a good shape
