[cgma-dev] CGM doc

[De Martin Florent]

Dear Vijay,

Thank you very much for your advices.

The mesh I would like to generate is very basic: only a cubic domain meshed by millions of hexa.  I generally use CUBIT, but unfortunately, the NetCDF API inside CUBIT fails to generate a mesh of 200+ millions of hexa. So I was looking for an open-source code (CUBIT is not) to generate such a mesh…

Best regards,
Florent

Hi Florent,

The doxygen documentation pages [1] and the website [2] provide some information depending on what you want to do. We currently do not have any examples in CGM and are planning to add few in the coming months.

For mesh generation, I suggest you please take a look at MeshKit, which uses CGM and MOAB underneath to handle the geometry and mesh queries, while optionally interfacing with external tools such as Cubit to generate high-quality meshes.

What is the general complexity in your geometry and what kind of meshes do you want to generate (HEX, TET. Hybrid) ? Also if you have any specific questions about the usage, do let us know.

Vijay
