Dear Gmsh community,
I'm fighting with Gmsh to set up a model of a quarter cylinder using the new
OpenCascade based facilities. The following script is considered:
SetFactory("OpenCASCADE");
cylinder = newv;
Cylinder(cylinder) = { 0.0 , 0.0 , 0.0 , 0.0 , 0.0 , 60.0,
175.0 };
box = newv;
Box(box) = { 0.0 , 0.0 , -50.0 ,200.0 , 200.0 ,200.0 };
lst() = BooleanIntersection { Volume{ cylinder }; Delete; }
{ Volume{ box }; Delete; };
pt_volume = lst[0];
Characteristic Length{ PointsOf{ Volume{:}; } } = 6.0;
However, the surface mesh on the (remaining part of the) cylinder is rather
odd, it contains one single layer of elements axially. (Please find attached
the image).
It's a bug in the MeshAdapt algorithm. Using the frontal algo (Mesh.Algorithm =
6) gives the expected result.
Can you open an issue in our gitlab so we can track this problem?
Thanks,
Christophe

How could I get a proper, isotropic mesh?
Thank you for your help in advance,
