Hey @younesssss,
Is there any way I can send you the scene directly? like email or some other form? and thank you for the help.

Hi @younesssss,
Sorry for the late reply, been very busy the past couple of days. I tried editing the Poisson ratio like you said but the difference isn’t huge, it is still not accurate with the force. I was wondering, would the collision mesh affect the force? I still haven’t added any for collisions of the arm with itself. Also for some reason…[Read more]

hi @younesssss,
I tried changing SparseLDLSolver to SparseLUSolver but my simulation just freezes when i click on animate. is there something I need to fix before when adding SparseLUSolver to make it work? all i did was switch SparseLDLSolver with SparseLUSolver. I don’t have much experience with SOFA so I am having a hard time trouble shooting…[Read more]

hi @younesssss,
Thank you for your response. for the Poisson Ratio I wasn’t really sure what to put, I wanted something that best fits spring steel. do you recommend going higher? I will try the SparseLUSolver and see if it is better that way.

That was calculated before I started working on this project for MATLAB simulation. I just used the same mechanical properties for SOFA.

Hello, I am trying to simulate a continuum arm in SOFA and I am having issues with cable actuation. The simulation of the arm models the real life arm very well at the same cable actuation displacement but for some reason the force is way off than the applied force on the real arm. For example at 21 mm cable actuation the arm should make the arm…[Read more]

momo replied to the topic Error Building SOFA with CUDA Plugin in the forum Building SOFA 6 months, 2 weeks ago
@hugo not for CUDA but the one thing I found is some of the plugins like STLIB are outdated and use macros that are no longer used so I added them back manually and also for the soft robots plugin you need to turn on SOFA_BUILD_METIS On but it does not show in the CMAKE GUI configure area so I also manually edited the src cmake file to turn it on.…[Read more]

This question is for anyone who knows this function or @damien-marchaluniv-lille1-fr as he is one of the people listed in the example Header.
So I am very confused on how to use this function, I took a look at rigidification.py but I am still not understanding how groupIndices and Frames parameters are used in that function.
This is what I am…[Read more]

Hey so I am developing an continuum arm simulation in SOFA and just starting. I want to make part of the arm elastic (the backbone to be specific but the rest of the arm rigid like the base and the disks around the arm). I was wondering if there is any way to specify what parts of a robot to be elastic? I looked in to the soft robots plugin but…[Read more]
