3D Mesh with hexahedra elements (basic question)
Posted: Tue Mar 26, 2019 10:25 pm
Hello, I am new in GID and I am trying to use it to generate meshes for finite element purposes. I am interested in hexahedra elements and I tried a very simple, example (i.e. a cube). To do that I created first a square using the line option in GID, then I converted this to a surface and after that I used the utility/copy tool to extrude the surface to a volume.
For the meshing I specified the element as a hexahedra and then tried to do the meshing, but I get the following message: "Volume number 1 can only be meshed with tetrahedra, and it has other element type assigned" and the mesh is not generated.
My understanding is that I should be able to do 3D meshes with hexahedra elements, but I am not sure what I am missing. Please could you offer some advice on this.
I also attach the message from GID
Thank you
