Thanks guys,

Yes it worked for me last week under 4.3.0. Today I downloaded 4.4.1 and it no longer works. I am using the Mac version.

Indeed, see attached png.
I am using latest Git linked against OCE 7.3.0 in GNU/Linux.

Hello Peter,

I’m using 4.4.0 (under windows), and your script seems to work for me…

Oggetto: [Gmsh] ellipsoid issue


I am trying to create some ellipsoids in 3D and came across this solution:


Sphere(1) = {0, 0, 0, 0.5};

Dilate {{0, 0, 0}, {1.5, 1, 0.5}} { Volume{1}; }

Characteristic Length{:} = 0.1;

Mesh.Algorithm = 6;

This was posted on the webpage



,however, the example appears to be generating one-point curves and so the meshing is failing.

I am using gmsh 4.4.1. I would be grateful for any suggestions and/or advice. I used a similar script before and not had this issue.

Thanks very much,
