Error trying export gmsh's mesh
 
Hi everybody!

I tried to export my mesh from Gmsh to OpenFoam with gmshToFoam but an error appeared. In order to learn about Gmsh I built a very simple geometry to try one more time. The error persist.
It is this:

Create time

#0 Foam::error::printStack(Foam::Ostream&) in "/opt/OpenFOAM/OpenFOAM-1.6/lib /linux64GccDPOpt/libOpenFOAM.so"
#1 Foam::sigSegv::sigSegvHandler(int) in "/opt/OpenFOAM/OpenFOAM-1.6/lib /linux64GccDPOpt/libOpenFOAM.so"
#2 in "/lib/libc.so.6"
#3
in "/opt/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64GccDPOpt/gmshToFoam"
#4 __libc_start_main in "/lib/libc.so.6"
#5
at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/x86_64/elf/start.S:116
Segmentation fault


I created the 0, constant and system folders with their corresponding files.

This is my .geo file

Point(1) = {0, 0, 0};
Point(2) = {0, 1, 0};
Point(3) = {1, 1, 0};
Point(4) = {1, 0, 0};
Line(1) = {2, 3};
Line(2) = {3, 4};
Line(3) = {4, 1};
Line(4) = {1, 2};
Line Loop(5) = {2, 3, 4, 1};
Plane Surface(6) = {5};
Extrude {0, 0, 1} {
Surface{6};
}
Physical Surface("entrada") = {28};
Physical Surface("salida") = {6};
Physical Surface("paredes") = {23, 19, 15, 27};
Physical Volume("internalField") = {1};


I did my .msh file using the tool "3D" in the menu "mesh" in Gmsh.

Any solutions?

Thanks a lot!

Dario.

Hi,

today I've been working on exactly the same thing. I therefore checked your geometry in my test project and it seems to work just fine. I'm using OF 2.1.x (git release) though, so maybe a simple upgrade to a newer OF version will do the trick.
