Hi everyone, I have a problem with meshing for OpenFOAM.


To make 3d mesh(.msh),
1. first, I made 2D surfaces and divided like this
Quote:
Point(1 ) = {0, 0, 0, 1.0};
Point(2 ) = {1, 0, 0, 1.0};
Point(3 ) = {3, 0, 0, 1.0};
Point(4 ) = {0, 2, 0, 1.0};
Point(5 ) = {2, 2, 0, 1.0};
Point(6 ) = {3, 2, 0, 1.0};

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

Curve Loop(1) = {6, 1, 2, -7};
Plane Surface(1) = {1};
Curve Loop(2) = {5, 7, 3, 4};
Plane Surface(2) = {2};
It can be seen at 'first_step(2D domain).PNG'.


2. second, I extruded surfaces like this.
Quote:
Extrude {0, 0, 1} {
Surface{1};
Layers{2};
Recombine;
}
Extrude {0, 0, 1} {
Surface{2};
Layers{10};
Recombine;
}
One of the two side-by-side surfaces was divided into 2 layers, and the other was divided into 10 layers.
And I got the problem in this step.

The error message is as follows, and the result can be checked at 'second_step(error view).PNG'.
Quote:
Error : Could not find extruded node (2, 2, 0.1) in surface 38
Error : Could not find extruded node (1, 0, 0.1) in surface 46
.
.
.
Error : Could not find extruded vertex (1.3750000001248, 0.75000000024958, 0.1)
.
.
.

I have attached the whole '.geo' file.
If someone knows how to solve this situation, please reply.
