Spheroid Meshing Issue

Spheroid Meshing Issue was created by BenWilson94
Hello,

I have produced a mesh for a spheroid with the attached .geo file, both using the GUI and from the command line using -batchmode. However, upon saving this as a .vol file (also attached) the geometry information is not contained at the bottom of the .vol file,
Code:
csgsurfaces 2 undef 0 undef 0

this, in turn, leads to a problem after loading the mesh with the following commands
Code:
ngmesh = ngmeshing.Mesh(dim=3) ngmesh.Load("Spheroid.vol") mesh = Mesh("Spheroid.vol")

and then attempting to use the command
Code:
mesh.Curve(5)

Is there something I'm doing wrong here?

Hi Ben,

No, you are not doing something wrong. The Ellipsoid class in Netgen doesn't implement the functions Get/SetPrimitiveData(), which are needed to save the geometry in a mesh file.
I will let you know when this is fixed.

Best,
Matthias

Hi Matthias,

Thank you for doing that, I am struggling to use the nightly release, has it been included in this? Do you know when the next stable release with this included will be?

Thanks again for your help,

Ben

Hi Ben,

Yes, It's included in the nightly, which I advise to use in your case (we are running the same test suite for nightly builds and stable releases).
I don't know when the next version is going to be released.

Best,
Matthias
