I am using Gmsh version 4.4.0, OpenFOAM v4.1, and Ubuntu 16.04.

I am receiving the following error when using a msh file saved using version 4 ASCII:

Starting to read mesh format at line 2
Read format version 4.1 ascii 0

Starting to read physical names at line 5
Physical names:6

Surface 2 front
Surface 3 bottom

I then tried to save using version 2 ASCII and received this error:

Since it is most likely my geo file code, here it is:

SetFactory("OpenCASCADE");

Circle(1) = {5, 0, 0, 1, 0, 2*Pi};

Point(2) = {0, -10, 0, 1.0};
Point(3) = {0, 10 , 0, 1.0};
Point(4) = {15 , 10 , 0, 1.0};
Point(5) = {15 , -10 , 0, 1.0};

Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 5};
Line(5) = {5, 2};

Curve Loop(1) = {3, 4, 5, 2};
Curve Loop(2) = {1};
Plane Surface(1) = {1, 2};

newEntities[] =
Extrude { 0,0,0.1 }
{
Surface{1};
};

Physical Surface("back") = {1};
Physical Surface("front") = {newEntities[0]};
Physical Surface("bottom") = {newEntities[2]};
Physical Surface("outlet") = {newEntities[3]};
Physical Surface("top") = {newEntities[4]};
Physical Surface("inlet") = {newEntities[5]};

Physical Volume(100) = {newEntities[1]};


Thanks in advance!

Hi ,

I am also getting the same error, with gmsh 4 and open foam 2.1. I have to check whether this is due the version sets.

Btw, did you find any resolution. ?

Hi,

I changed the ASCII to 1, and it worked. I believe it the version matching that is required.
