Hello Karen,
Thanks Wolfgang, Markus and Florian. I think I will try to get my grid
into a format (hex, where I used to have tetrahedrons) that deal ii
uses for 3D. Deal ii doesn't generate a mesh given points right?
No, deal.II cannot create a sutable mesh for some given points itself.
You can have a look in the class GridGenerator and check if there is
some suitable geometry for you. There are also some grid generators
available that can produce hexahedral meshes, e.g. CUBIT, LAGRID.
Unfortunately they are not open source, so you have to take special care
of the licence.
For me all the data is at the vertices, so I don't necessarily have to
have tetrahedral elements. (Just double checking...)
In general you do not need tetrahedral elements, but it can be very
tricky to create a mesh with hexahedrals for some complicated geometry.
Best Regards,
Markus
