Re: SketchUp - Salome Meshing Work-Flow

I used the Push-pull tool in SketchUp8 (windows 32 version) to create one surface on top of another but it seems that as I define groups the interfacing face can only be defined for one of the two groups and not for both. It is quite some time ago that I wrote this script and I haven't used it for ...

Re: SketchUp - Salome Meshing Work-Flow

I have uploaded a new version. Plese note, that your design is scaled in meter, but the box where you give the mesh sizes accepts mm. You have to give rather big values then to have a reasonable mesh count - otherwiese Salome will crash with a memory error. In Sketchup you also can select a template...

Re: SketchUp - Salome Meshing Work-Flow

Yes, there is a bug in the script - I will upload the corrected one tonight.
The script for multiple bodies works, the one for one body has the bug.

Re: SketchUp - Salome Meshing Work-Flow

Hello,
try to not use whitespace in filenames or the Group names, also avoid language specific characters - both may cause problems.
The name of the py script is the name of the sketchUp file, so you have to rename it.
If this does not help, send me the skp and the generated .py.

Re: CAD designer

What do you want to do? Simulation models? Mechanical CAD? What type of models do you intend to create? For entry level I suggest SketchUp - there are very good training videos available that allow a super easy entry. It is not mechanical CAD however but if the intended geometry is not too complex i...

Re: gmsh: how are physical surfaces numbers by ElmerGrid?

Hi there is a difference how you create the elmer mesh. If you use ElmerGrid for conversion the boundary indexes start at 1, if you use ElmerGui they are different, I think here it depends on the number of bodies. At least for salome meshes it works that way. In any case you can open your mesh in El...

Re: SketchUp - Salome Meshing Work-Flow

SketchUp models all as polygons. At least for circles and cylinder / cone surfaces I retrieve the curvature and pass it via IGES to Salome. For the moment that satisfies my needs. I have however used spline interpolation within SketchUp to avoid these problems in other applications. Up to now I did ...

SketchUp - Salome Meshing Work-Flow

If the simulation geometry is complex or there are multiple bodies involved generating the mesh is a major task. The mesh generators have GUIs difficult to use so often it is required to code the geometry in the form of a script. Besides the big effort this is inflexible and error prone. On the othe...

Salome multi-body meshes form CAD files with python script

There is a description in the Wiki how to create a multi-body mesh with Salome. This works perfectly but assumes that the geometry is defined within Salome. And the process is fairly complicated including several steps. I found that the process also works when the bodies are loaded into Salome from ...
