Meshing available in Harpoon
Harpoon is extremely useful for creating quick meshes with very little effort.
One of its major strengths is that it does not require
a water tight surface mesh, so it can cope with non
perfect CAD geometry. If, however, you have already
invested the time to create a surface mesh with specific
cell distributions, now you can have all the benefits
of a Harpoon volume mesh while conforming to the
initial surface mesh.
This new conformal function is called the Matched
The image to the right shows an idealised surface
mesh of a torso which Harpoon has conformed to. This is managed by use of a Delaunay meshing algorithm
to match the the triangular surface mesh with the
Harpoon Hex dominant volume mesh.
This new functionality
is controlled on a per part basis allowing the user
the ability to generate meshes with some parts of the
mesh conforming to the imported surface mesh and other
parts meshed in the traditional Harpoon manner. This
is particularly useful where
the geometry becomes dirty or control of the surface
mesh distribution is not so important.
The image to the right displays this functionality
on a simple model consisting of two spheres. The top
sphere in the picture shows normal Harpoon
meshing and the bottom one shows the mesh conforming
to the surface mesh of the sphere.
The matched mesh function is also available on zero
thickness parts allowing the user complete control over
the type of meshes that they now wish to generate. The
image below shows a matched mesh on such a part.
This new Matching feature is another extension to Harpoon's
ever growing feature set allowing you flexibility in
how you approach problems with meshing.
More information on this new functionality may be found in Harpoon’s User Guide, viewed through
Harpoon’s “Help” facility.
