Would it make sense to provide some default integration schemes in which you can specify the number of Newton steps done per time step?

Please, finish the “Main principles” documentation!

I think that it will be nice to have some kind of tool to look for a component and get feedback about the available templates and the data names for the .scn file.

I know that with the Modeler you can do this, but I think that a lighter application to just search for a component and getting the…[Read more]

Hi Hugo,

in fact it have some relationship as I’m simply trying to understand how constraints work.

The main issue I’m facing in this example is that the LMConstraints are not being applied, but the solver is added in the scene :-s

Thanks!

Thanks Hugo!

I will have a look at StateMask and try to compile the plugin.

Finally Ive been able to compile v16.12. The problem was that FileRepository.cpp wasn’t added to the project so some functions weren’t found. This problem was due to some missing boost libraries (in particular, FileSystem).

It’s not working neither. I have tried with GCC 5.4 and both options for _GLIBCXX…
Qt is compiled by myself, but it’s compiled with GCC5.4 also….

Right now nothing important, just some playing with SOFA and state of the art force models like VegaFEM or ArcSIM.

So if I understand correctly, for a FF or a MO to take care of the addtion, deletion or modification of topology, the topologyDataHandler must be implemented? What happens when this modification affects a mapping? Does the current…[Read more]

Great, thanks Perdon.

Just one more question. When I modify a triangle, how are the new mechanical DOFs for the new vertexes calculated? For example if I remove one triangle and insert 3 triangles inside, in order to refine the mesh, there will be one extra vertex. If that mesh is used for cloth computations, how are the velocities, strain… computed?

I was thinking about an engine which after each frame, updates a scalar field stored in the nodes and based on that scalar field, check which triangles should be refined or coarsed. So maybe I can inherit from topologyEngine to do this 🙂

Thanks

I would use the CGAL plugin which has two nice components to compute a tetrahedron mesh from a surface mesh or from an image. I have been using this approach to generate tetrahedron meshes of random meshes and it works pretty well.
