Re: How to create segments on an irregular geometry
If do you have a CAD model of your shape, created with NURBS then can divide it in parametric directions u or v with Geometry->Edit->Divide->Surfaces (num divisions, or near point or parameter) -num divisions simply divide in n parts in space parametre -near point will calculate the u,v parameters f...

Re: How to refine grids at special points
Instead the original surface you can create another modified geometry creating the points at these forced node locations, connect them with lines and surfaces. or alternatively can create the points and force to be on the mesh of the original surface with Mesh->Mesh criteria->Force points to->Surfac...

Re: Reading Post Process file
Probably the results of the mesh files of post are bad.
Attach a zip file with the model to try it

Re: Mesh around an opening and other mesh-related queries
1- you are wrong. In a semi-structured volume you can concentrate mesh sizes in the surface normal to the extrusion direction, but off course must do the same concentration in both linked tops. e.g. I have assigned a number of divisions=8 to the lines of the holes of the tops (can also assign a mesh...

Re: GID 16.0.6 crashes when splitting hexahedral meshes
I don't know what do you mean by "I can't mesh it properly around the opening" How is the mesh that do you want? You can generate a mesh of your model: - unstructured (tetrahedra only) - semi-structured in Y-direction for the 3 volumes - semi-structured the central volume and fully structu...

Re: How to postprocess from OpenSees
This task to convert results if required to GiD results format (or some format imported by GiD) was done by the 'GiD-OpenSees' problemtype developer. As 'final user' simply must calculate (menu Calculate->Calculate) and if successful the results file are created and can see the results in postproces...

Re: Problem with postprocessing
To view in postprocess the results, these results must exists (<modelname>.post.res, ...) , calculated by the problemtype solver. Probably the solver is not able to do the calculation because some problem with boundary conditions, mesh, ... and probably is writing some error message. (try in pre the...

Re: How to solve the problem of creating a mesh
The answer is the same: attach a zip with the specific model
And off course try always to use the last available GiD version (developer and or official)

Re: Just a simple Cube problem.
If you are used to the 'OpenSees' Tcl format you can modify your copy of the GiD problemtype, and add a to the OpenSees.cnd file a new condition similar to Surface_Forces but named for example Surface_Pressure, with a definition similar to this CONDITION: Surface_Pressure CONDTYPE: over surfaces CON...

Re: Just a simple Cube problem.
The opensees classic problemtype developer has decided that its condition named 'Surface_Forces' over surfaces is transferred to the nodes when meshing other possibilities were 'over face elements' and will mark the faces of the volume elements touching the surface or 'over body elements' and then i...
