Hi @jangirrishabh

Sorry for not getting back to you earlier. But the SOFA Week kept us busy (with many scientific presentations and technical discussions) and I am current out from the office.

There have been discussions on update. A summary will be made available on the “RoadMap” page on sofa-framework.org. Shortly, a new working project is…[Read more]

About Paraview, I just meant that you can visualize 3D volumetric meshes with it.
Paraview can do it, with crop options (like SOFA) and others.

Next time we met, we can have a Paraview tour together but I am no huge expert of the latest versions.

Just two short remarks

PS: note that using UncoupledConstraintCorrection strongly simplifies your finger model in the constraint resolution.
PS2: note that the time step has (as always) a strong importance in the stability of your simulation

Dear @nicklj

Thank you for your super enthusiastic reply! The SOFA week is actually the success of the entire community, from PhDs, researchers to industrial partners. We are glad to see the community growing and increasing its simulation activities. It would definitely be a pleasure to get further contributions and to have you with us next…[Read more]

Hi @noura

As you know, we usually use Paraview.
If it doesn’t work in SOFA I like to use the TetrahedronSetGeometryAlgorithms: by hiding the VisualModels, you can then set drawTetrahedra=”1″ and set the scaling to drawScaleTetrahedra=”0.8″ this is not bad.
Finally, for advanced render, I would go for Blender ..

I hope this helps
Cheers,

Hugo

Hi @ma1991

I am sure SOFA can be your holly grall!
I guess you don’t want to limit to the simulation of one yarn, right? you would like to have several yarns interacting, colliding etc. right ?
A volumetric modeling as the one in your video is fine for one yarn but it will quickly become too computationally demanding. Unless you use some…[Read more]

When research from France assist research from Colombia!
Cool to see, thanks @ant0nin, I had not even the time to reply.

Hi @outtt

It is a private plugin belonging to a research team. I don’t know the plugin myself but I can gather information if needed. Then, the discussion would be pursued per email for academic or commercial licensing if it fits your needs.

However, I think before triggering this administrative step, it would be good to understand in which…[Read more]

If my previous reply answers your question, do not hesitate to close this topic.
You can open a new one anytime.

Best wishes,

Hi @charles,

I see you are still digging in the papers.
The collision in SOFA works in three steps: broad detection check (using coarse BVH), narrow detection (several options here, by default using discrete intersection) and response.
In the paper we are following this process with:
– broad phase using BVH
– narrow phase using discrete…[Read more]

Dear @nicklj

I am really sorry for the delay of my reply, we have been busy with the SOFA Week. You can find out more about this annual community event on SofaFramework’s YouTube account.

I don’t whether you can share a (simplified) version of your rigid object grasping a deformable one. It would help knowing which collision detection you are…[Read more]

Hi @outtt

All beam approaches can not be deformed radially since it is actually the definition of the method: one direction (length) is significantly greater than the two other ones (section).
In the community, vessels are usually represented by beams because the added stiffness due to their presence is of interest. They are also sometimes…[Read more]

Hi @eyadshak

Let me notice @faichele for you since he’s the author of this ROS connector. I hope he will be able to assist you.
Best wishes,

Hi @jjcasmar

I agree with you that default integration schemes do not involve Newton steps. It is a pitty. However, the VariationalSymplecticSolver or the StaticSolver are doing it.

Ola @jjcasmar

Good to have you back on the forum!
In SOFA MultiMapping does exist. Do you want to implement your own mapping or using an existing one? Could you provide us a bit more insight on what are your “states” that you want to map?

See examples in examples/Components/mapping/IdentityMultiMapping.scn or SubsetMultiMapping.scn

Cheers,

Hugo

Dear @nguyenvanpho

Welcome on the SOFA forum!
Have you carefully read the doc on the Linux compilation of SOFA? Especially on this Qt paragraph.

Is the configuration stage finding Qt5 properly?

Hi @priya-vada4

First of all, welcome in our open source and free forum!
From what I understand you downloaded the sources of SOFA and you compiled it. Right? Did the compilation process run properly?

I see the problem, but before giving a complete answer could you please explain what you want to do from the position of these points ? do you really…[Read more]

Hi guys any update on this topic ?
