Matched 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 Mesh feature,

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.
