<br>
i have a problem in creating my desired mesh for a cube. This is what i<br>
want to do:<br>
1. Creating a plane surface<br>
2. Inserting some points on this surface<br>
3. Creating a surface mesh where the points from step 2 are considered<br>
4. Extruding the surface mesh to a 3d-prism-mesh with several layers<br>
<br>
For me it is important that the surface mesh is extruded as a structured<br>
mesh, because i need nodes vertical under the points inserted in step 2<br>
for line elements later on.<br>
This is the script for my test example:<br>
<br>
sl = 100.0; // Geometry parameters<br>
a = sl/2.0;<br>
Point (0) = {0, 0, 0, 1}; // Point to be included<br>
Point (1) = {-a, -a, 0, 10}; // Corner points<br>
Point (2) = {a, -a, 0, 10};<br>
Point (3) = {a, a, 0, 10};<br>
Point (4) = {-a, a, 0, 10};<br>
Line (1) = {1,2}; // Lines forming the rectangle<br>
Line (2) = {2,3};<br>
Line (3) = {3,4};<br>
Line (4) = {4,1};<br>
Line Loop (5) = {1, 2, 3, 4};<br>
Plane Surface (0) = {5}; // Creating the plane surface<br>
Point {0} In Surface {0}; // Forcing my important point to be on<br>
the surface mesh<br>
Extrude {0, 0, 10} { Surface {0}; Layers {1}; Recombine; } // Extruding<br>
Mesh 3; // Meshing<br>
<br>
This script creates a mesh and extrudes the surface mesh except the<br>
elements that are connected to point 0. GMSH says<br>
Error : Could not find extruded vertex (0, 0, 10) in surface 27<br>
and then repeatedly<br>
Info : Linear search for (0, 0, 0)<br>
Error : Could not find extruded vertex (0, 0, 0)<br>
<br>
I am not sure if this is a bug or if the extrude-feature doesn't work<br>
like i expect or if there is another way to achieve my desired mesh.<br>
<br>
Thanks a lot and many greetings,<br>
<br>
