[cgma-dev] CGM doc

[Grindeanu, Iulian R.]

Hello,
CGM alone would not be enough to generate a mesh
CGM is mostly a wrapper around other geometry kernels, ACIS or OCC/OCE based.
To generate a mesh you would need the SIGMA stack.
http://sigma.mcs.anl.gov/

I am not familiar with what format you need your mesh for EFISPEC3D; I assume it is similar to NEK5000 solver, which is a spectral element method too. (so Nek needs a hexahedral mesh)

And what is the input geometry format? Terrain data?
We have some capabilities developed for ice sheet modeling. At the core, they do need a quadrilateral mesher for surfaces, which are then extruded/swept to form hexahedral elements. Also, it is assumed that the domain of interest does not have internal caves/tunnels, so the sweeping in vertical direction is trivial.

I am not sure how these would help your project.

Iulian

Dear CGM support,

I am interested to generate large scale finite element meshes for the spectral-element code EFISPEC3D (http://efispec.free.fr)
I have downloaded (from git) and compiled CGM, but I can hardly find a user documentation. Would you please send it to me ?

Best regards,
Florent DE MARTIN
