I am trying to read multi-block grid generatey by GMSH version 4.12.2 but somehow it fails.
lc = 100;
cx = 324925.0;
cy = 5216025.0;
s = 3000.0;
r = 16000.0;
// Number of cells at inner square
Ns = 12;
// Number of cells between inner square and circle
Ni = 36;
// Horizontal gradings
blockGradi = 1.1;
blockGrads = 1.0;
// Inner square side curvature - 0.4
scr = 1.1;
sc = s * scr;
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

// Gmsh provides other curve primitives than stright lines: splines,

Mesh.CgnsExportStructured = 1;

// Mesh.Format = 28; //P3D
but somehow, the file is still corrupted. Any idea where this comes from?
I must point out that I am running it in a container and that the files are written on a CIFS volume. I will try to write them under '/tmp', maybe this could be help.
