Hi, I´m wondering how "magic" is harpoon, like they say. I couldn´t get my demo due to some errors, but I would like to know how is Harpoon. Do you have to do a lot of work like others meshers in order to get a structured grid?

Thanks!

You don't get a structured grid. What you get is an unstructured hexa dominant grid, either with hanging nodes or with tetra between small and large grid cells. Harpoon is not an easy way of getting a good mesh, it is a quick way of getting a big mesh, especially for nasty geometry. It really comes into its own if you have the computing power (and parallel licenses) to handle very large grids. The advantage is that you don't spend a lot of time on meshing, you basically capture the detail you need with a large unstructured hexa mesh, which Harpoon generates very quickly.

Hi,

Someone posted his feedback after testing harpoon a while back on this forum. You can find it by doing a search on the main forum.

HArpoon is ok for getting big size and quick meshes for some slivered, angle skewed geometries. May be better for developing hex in effcient way.
