absorbing boundaries (made of QUAD). But unfortunately, the NetCDF API inside CUBIT fail to generate a mesh of 200+ millions of hexa. The mesh is very basic: only a cubic domain meshed by millions of hexa. So I was looking for an open-source code (CUBIT is
not) to generate such a mesh…<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black">Hello,<br>
CGM alone would not be enough to generate a mesh<br>
CGM is mostly a wrapper around other geometry kernels, ACIS or OCC/OCE based.<br>
To generate a mesh you would need the SIGMA stack.<br>

<br>
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.
</span><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black">(so Nek needs a hexahedral mesh)<br>
<br>
And what is the input geometry format? Terrain data? <br>
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.<br>
<br>
I am not sure how these would help your project.<br>
