Hello

I am trying to make a cube in GMSH, mesh it and then using gmshToFoam convert the code. But i dont know what is wrong. I am starting with gmsh and OpenFoam if someone could help me please.

GMSH.
// Gmsh project created on Thu Oct 04 16:20:25 2018
SetFactory("OpenCASCADE");
lc = 0.1;

//Puntos

Point (1) = {0,0,0,lc};
Point (2) = {1,0,0,lc};
Point (3) = {1,1,0,lc};
Point (4) = {0,1,0,lc};
Point (5) = {0,0,0.1,lc};
Point (6) = {1,0,0.1,lc};
Point (7) = {1,1,0.1,lc};
Point (8) = {0,1,0.1,lc};

//Lineas

//Block
Line (1) = {1,2};
Line (2) = {2,3};
Line (3) = {3,4};
Line (4) = {4,1};
Line (5) = {5,6};
Line (6) = {6,7};
Line (7) = {7,8};
Line (8) = {8,5};

//laterales

Line (9) = {5,1};
Line (10) = {6,2};
Line (11) = {7,3};
Line (12) = {8,4};

//Superficies


Curve Loop(14) = {4, 1, 2, 3};
Plane Surface(14) = {14};

Curve Loop(15) = {6, 7, 8, 5};
Plane Surface(15) = {15};

Curve Loop(16) = {4, -9, -8, 12};
Plane Surface(16) = {16};

Curve Loop(17) = {7, 12, -3, -11};
Plane Surface(17) = {17};

Curve Loop(18) = {6, 11, -2, -10};
Plane Surface(18) = {18};
//+
Curve Loop(19) = {10, -1, -9, 5};
Plane Surface(19) = {19};

Surface Loop(1) = {14, 16, 19, 18, 15, 17};
Volume(1) = {1};

Physical Surface("bottom") = {14};
Physical Surface("top") = {15};
Physical Surface("left") = {16};
Physical Surface("right") = {17};
Physical Surface("front") = {18};
Physical Surface("back") = {19};

Physical Volume("internal") = {1};

Thanks and Best Regards.

The problem is I think due to how new version of gmsh is creating the mesh. Version 4.0 of gmsh creates the .msh file in ASCII v4 however gmshToFoam is created for ASCII v2. You can find the solution to this issue in the following discussion:
