Local remeshing of a tetramesh can become necessary if baffles have to be included in
an existing mesh or if the mesh has to be refined locally.
To include baffles, in the Tetra Remesh subpanel, use the elems button under the 2D baffle
elements heading to select the baffles and click remesh.
For a local remesh, select the relevant refinement box in the Tetramesh parameters
subpanel, and hit the remesh button on the Tetra Remesh subpanel. Figure 1.
Free Boundary Faces in the Tetra Remesh Subpanel
The Free boundary faces option affects those faces of tetra elements which are on the
outside of the volume, meaning the tetra faces which have only one tetra attached. Those
faces are called free boundary faces.
There are three options when selecting Free boundary faces:
fixed
The free boundary faces are fixed.
swappable
The edges of the free boundary faces can be swapped. The mesh nodes stay
unchanged.
