CFD Online Discussion Forums - [Gmsh] Gmsh physical line and .msh

Hi all,
I've got a problem with gmsh with this code

Code:

Point(1) = {-1, -0.8, 0, 0.3}; 

Point(2) = {0.3, -0.8, 0, 0.3}; 

Point(3) = {0.3, 0.3, 0, 0.3}; 

Point(4) = {-1, 0.3, 0, 0.3}; 



Line(1) = {1, 2}; 

Line(2) = {2, 3}; 

Line(3) = {3, 4}; 

Line(4) = {4, 1}; 



Line Loop(5) = {4, 1, 2, 3}; 

Plane Surface(6) = {5}; 



Physical Line("test")={4};

when the last line about the "Physical Line" is comment, the .msh contain all, but when it's not comment, the .msh is

Code:

$MeshFormat

2.2 0 8

$EndMeshFormat

$PhysicalNames

1

1 1 "test"

$EndPhysicalNames

$Nodes

5

1 -1 -0.8 0

2 -1 0.3 0

3 -1 0.02500000000071845 0

4 -1 -0.2499999999984228 0

5 -1 -0.5249999999991237 0

$EndNodes

$Elements

4

1 1 2 1 4 2 3

2 1 2 1 4 3 4

3 1 2 1 4 4 5

4 1 2 1 4 5 1

$EndElements

And does not containt the mesh...
Do you have an idea about that?
Thanks for your help!
