Dear Mark, By now there is no tutorial for the boundary layer meshing. However, it is very simple to use: The only thing you have to do is select 'Mesh-Boundary layer-2D or 3D', and select the entities. For 3d, for example, first of all you have to select the volumes into which the boundary layer me...

Dear Samir, To get the line mesh and the surface mesh, you have to set Mesh-Mesh Criteria-Mesh-Lines and select the lines you want. The same happens if you want to have a volume mesh and also the mesh of its boundary surfaces. Doing this you will get both meshes, but they are conformal. If you want ...

Dear Luis, It seams that the two lines which form the ContactSurface are sharing their starting and ending nodes. Each geometrical point can only generate one mesh node. To solve this problem, you must duplicate the nodes, so as each line have its own geometrical starting and ending point. Regards, ...

Dear Chen, The way to ensure that you are using the same Meshing properties (the ones which appear in the Preferences-Meshing window) that the model had previously is to set Utilities-Status-SetMeshOptions. This function load the meshing properties saved with the model. Regards, ABEL _______________...

Dear Jonas, Depending on the shape of the surface to be meshed, some node is added or not, when a unstructured mesher is used. In your case, you have a four-sided surface, so you can generate a structured mesh on it. If you set a structured the surface, you assign "Triangle" as its element...

Dear Nacho, No, this option is not available in GiD by the moment. The only thing you can do is to split de surface in a way that the line own topologically to the surface.

Just add to Enrique's explanation that you can also obtain hexahedra meshes using semi-structured meshes (structured in the prismatic direction of the volume, and unstructured in the "tops"). You can assign this kind of mesh by "Mesh-Semistructured-Volumes". Regards, ABEL _______...

Dear Enrique, I'm Abel, from the GiD Team. Please, can you provide me with the model (in the format which are you reading it from GiD), so as we would be able to detect the possible bug? You can send it to me directly ( abelcs at cimne.upc.edu ). Kind regards, ABEL _________________________________ ...

Dear Mauricio, You can divide a quadrilateral mesh into a triangular one using 'Mesh - Edit Mesh-Split Elements - Quadrilateral-Triangle' option. Once you have the new triangles they should work as the other triangular meshes, so you can use them normally as a background mesh. Note that the quadrila...
