Hello @rainvector

I do not think only BeamFEMForcefield is sufficient. Because using rigid dofs with BeamFEMForceField can only make surface mesh deform globally but not locally.

You can try to construct your example scn and test if it is true.

Hello @hugo

I have ever thought about rigid dofs mapped from vec dofs with TetrahedralCorotationalFEMForceField. But I do not think the tetrahedral elements are suitable for a tubular model. The size of the element would be small and the number of the elements would be very large so it would lead to high overhead and low frame rate.

So I think a…[Read more]

Hello @nickhockings,

Although I built it successfully but actually I want to report that there were some compile errors which occured in VS2015.

like in load_surface_meshes.cpp line 35
YAML::Node config = YAML::LoadFile(it->c_str());
should be change into
YAML::Node config = YAML::LoadFile(it->string());

And there are some other places using…[Read more]

Hello @hugo,

luckily, I tried to buid it and I succeeded! Only CGAL and Yaml-CCP should be built threre, other dependencies can be directly downloaded and used.

I would continue to test it if there are bugs there. But I think it is hard for me to read the code about CGAL and there is very few information and tutorials on the Internet about how…[Read more]

Hello @olivier-goury

Do you know about this？

Wong

Hello

I think you can take a look at this link to see if it is suitable for you.

Hello @hugo,

Can you tell me how to use MeshMatrixMass because there is no existing example.

I use RestShapeSpringsForceField because I do not want to make the fixed part so hard sometimes.

Hi @Hugo,

Have you gotten back from holidays?

Wong

Sure, I will @ you on December 17.

Hello @hugo,

Just want to drag or block the artery/vessels and clip the aneurysm. So the level of accuracy should be fairly high.

Wong

Hello @hugo,

Just deform flexibly like the real one, from all directions and keep the performance in persisting contact. Because the vessels are located in the gap of the soft tissues.

Hello @hugo,

Where can I find the plugin using shell model?

Wong

Hello @yordan-kyosev

I think the situation is more complicated than you think. What I want to model is something like vessels. So you have to think on the case that the rope has branches.
As far as I can see, representation of beam is still nothing more than a strings of rigid bodies. It may cause low performance having masses of rigid frames and…[Read more]

Hello @epernod

By the way, now how are your TopologicalModifiers coming along in volumetric cutting? I think the topological change for tetra mesh at runtime could help deal with this problem.
