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] -
Hugo replied to the topic How to determine the source of an stress sigularity? in the forum Programming with SOFA 1 year, 5 months ago
Hey @charles
Understanding the source of an error is physics simulation is often complex due to the different possible cause of errors, as you explained. Therefore, there is no straightforward answer.
Numerical analysis is one the main key : analyzing the system matrix, the force vectors, the convergence of the solver and the input parameters.…[Read more]

Hi @charles
You are talking about a 2006 paper! I was even not done with my studies!
I don’t see the appropriate equations that you mention. Can you indicate me using the linked paper above?
A more recent paper is available here: Interactive simulation of embolization coils: Modeling and experimental validation
Again, this corresponds to the “C…[Read more]

Hugo replied to the topic How to set a node's rotation in the c++ code? in the forum Programming with SOFA 1 year, 6 months ago
Hi @charles,
You can specify to your MechanicalObject (containing the rigid frames) their position and orientation with a quaternion.
I think the ArticulatedSystemMapping is close to what you need but I remember struggling a bit myself using it, but it’s worth having a look (in examples/Components/mapping)Best

Hi @charles
Yes I do.
How can I help? Would you be interested in getting access to the related simulation code?If so, you can contact me directly by clicking on “Get This Plugin” on the associated Marketplace item.
Best wishes,

Hugo replied to the topic The price of a plugin! in the forum Getting Started 1 year, 6 months ago
Hi @charles
I am really sorry for the delay of my reply to your private email. I answered it. We are currently very busy focused on the SOFA Week.
Prices can not be directly provided since authors / institutions owning the codes have different practices. Moreover, prices depend on many parameters like use, domain of use, exclusivity etc.
Let’s…[Read more]

Hi @charles
I therefore close the topic.
I apologize for the delay, we are currently very busy organizing the SOFA Week 2019 and the next steps for SOFA in 2020! I’ll get back to you before the end of the week.Best

Hi @charles
You did well opening a new topic.
You selected Win, is this your OS?
Have you paid attention to the doc on boost, during the compilation?Hugo
