Hi,
I believe that there is a bug in the coloring algorithm. When I import and
mesh a step file containing colored faces the resulting mesh cannot be colored
by Physical Group. The mesh is instead colored based on the geometry surface
color.
Also, I read that 3D boundary layer meshing may
To whom it may concern,
I think there's a bug in the gmsh 2.12.0 for linux.
When saving a mesh in .su2 format the final output contains also geometrical
points which are not mesh nodes.
For instance, if I want to create a domain with an inner circular void region,
i will need to create a poi

Hi, this "as-short-as-it-gets" code produces an erroneous mesh. The bug
gets worse as the cutting plane gets closer to the equator of the sphere.
Is this fixable?

Sphere(3) = {0.95,0.2,0.2,0.7, -Pi/2,Pi/2, 2*Pi};

We are working on it - it's not perfect yet, but the latest nightly snapshot
works on your test-case. Give it a try?
(The issue is linked to the way OpenCASCADE deals with e.g. spheres, which
involves singular parametrizations.)

I was using a code I developed in version 4.4 for meshing spheres with

Moreover, I’ve been using this code in different incremental updates and it
worked perfectly until version 4.5.3. Yest

I have tried installing the newest GMSH from source code. First problem I

Adding the -lgfortran to the C and CXX Cmake compile flags fixed the problem,
and I could compile gmsh.

Does the latest snaphot produce the same invalid mesh? If so, can you try

Dear all,
I generated a mesh with the latest version of gmsh available via svn using a
step model, and exported it as a msh file:

Mesh.Algorithm=5;
Mesh.Algorithm3D = 1;
Mesh.Optimize = 1;
Mesh.OptimizeNetgen = 1;
// Geom parameters

Ok I figured it out, my custom-compiled Lapack did not have dynamic libraries...
Sorry for the noise,

Dear Pierre - Which version do you use? Nicolas Tardieu provided a patch in
Gmsh 2.16 which should fix this.

Hello Julien,
Indeed, HEX27 export is not coded yet for Abaqus. Could you have a look at the
MHexahedron27 class in
https://onelab.info/svn/gmsh/trunk/Geo/MHexahedron.h (login and passwd: gmsh)
and provide the little "virtual MVertex *getVertexINP(int num)" function?

Minor issue: The value of the "print messages on terminal" option is not
saved with the other options. It is always initially unchecked on program
start.
By contrast, options such as "message verbosity" save with no issue.

Indeed - this is now fixed in SVN.
Thanks for the report!
Dear all,
I was happy to see that the new gmsh version (2.14.1) includes the
long-missing "Point In Volume" feature.
However, if multiple volumes are created in the .geo file, with points
added to each volume by "Point In Volume", then only the points lying in
the *first* volume are meshed in
Dear List,
I am trying to extrude a rectangle with a rotation by PI. However this
results in a flat surface instead of half of an cylinder. Please find a
minimal .geo example below.

Dear Gmsh developers,
I have recently moved from Gmsh 3.0.6 to the most recent 4.3.0, and I have
noticed that the .msh files for extruded meshes with layers are slightly
different than before, because they contain periodicity relations.
To me this is puzzling, because I do not have any periodic
Dear Gregor,
Indeed, this was only supported with our new Delaunay algorithm. I've fixed the
old algorithm so that it works there, too.

Dear Daniel,
That's expected with the built-in kernel, which only supports circle arcs < Pi.
Use the new OpenCASCADE integration for such things: just add
SetFactory("OpenCASCADE"); at the begining of your file.
