mbskin

Generate input files for testing Mesquite (MESh QUality Improvement Toolkit). Produces a mesh in which interior vertices are marked free and skin (boundary) vertices are marked fixed.

Synopsis

mbskin  <input_file>  <output_file>

What it does

1. Reads the input mesh.
2. Finds the set of all elements of the highest dimension present (volume elements if any exist; otherwise face elements).
3. Generates the skin of that set of elements.
4. Creates an integer tag named fixed.
5. Sets fixed = 0 on all interior vertices and fixed = 1 on all vertices in the skin.
6. Writes out the set of elements with the new tag.

Example

mbskin  volumes.h5m  volumes_fixed.h5m
# Output has a `fixed` tag: 0 on interior verts, 1 on boundary verts.

Notes

• The "fixed" naming is a Mesquite convention; vertices with fixed=1 are held in place during quality improvement.
• Works on any mixed-dimension mesh by picking the highest dimension present.
