When to use unstructured triangular mesh In multiphysics?
The main use is to “test mesh” individual faces; in particular, faces where we have applied virtual operations. We can investigate the mesh quality on individual faces without having to mesh the adjacent volume. Unstructured triangular mesh can also be useful as a starting point for swept meshes.

What are the best practices for meshing in nimbix?
Proximity and curvature meshing will allow you to capture the small details of the part and the curvature of the solid bodies. Now let’s dive into some best practices for meshing in general. We’ll even cover some tips and tricks you can use.
Do you need to fillet the corners of a mesh?
Remember to fillet interior corners as sharp re-entrant corners result in stress singularities. The more you refine, the more the stress never converges to the true value. Adding a fillet removes the infinite stress, but interior fillets usually need a reasonable amount of mesh refinement [2].
How are surface meshes built in COMSOL Multiphysics?
The Free Tetrahedral operation builds surface meshes on unmeshed faces before it builds volume meshes. The surface mesh must conform with geometry boundaries, but the Surface Mesh nodes can be moved around within the faces during element quality optimization.
Do you need structured mesh or unstructured mesh?
That would make the transition to the rest of the unstructured mesh more difficult and would not actually improve things, since the swirling motions that we expect behind the “car” are relatively isotropic, meaning that a structured mesh would also need to be more or less isotropic.
How many vertices does a tetrahedral volume mesh have?
In most cases a tetrahedral volume mesh can be generated automatically. A quadrilaterally-based pyramid has 5 vertices, 8 edges, bounded by 4 triangular and 1 quadrilateral face.
Why do you need something to mesh a tetrahedron?
A tetrahedron only has triangular sides, so something is needed to transition from faces with quadrilateral elements. This “something” is the pyramid. A pyramid element is formally a hexahedral element where one of the element faces is collapsed into a point, leaving an element with one quadrilateral face and four triangular faces.
