I have a Realsense depth Camera D435. I also installed the part of the soft robot plugin that include for example the point cloud processing and the force exstimation from the camera. I found this interesting but I don’t find any example scene as tutorial.
Anyone have something?
Thanks in advance.
I explain a bit how I am conducting my research.
I am basically demostrating on how the soft robotic controllers can be more accurate if we have a good model of the material that we generally use… Also because as you might know, I am working for particular materials.
For a kinematic control, i started from static test on my…[Read more]
I am currently using for my research Sofa in Hyperelastic force field, and I find it very accurate.
But in future I will evolve my research treating viscoelastic material and so modeling the viscoelasticity.
There are viscoelastic models or Force fields in Sofa? Can you talk me about all the possibilities?
Thanks in advance!
Yeah as Said many people before me, GitHub discussions offer a Better tracking of the problems and what people are working on.
It would be good also to have like a sort of “Discord” or Telegram Group,where people can ask for technical issue about Sofa and resolve the problem/get answers in short-time.
Keep me updated.…[Read more]

I am working a lot and having quite good result. I am also enjoying the Mesh partitioning tool for multimaterial simulation.
The fact is that, it works only for linear elastic forcefield, because the localstiffnessfactor “variable”list is present only there. So i will appreciate if this varialble is present also in…[Read more]

Sorry for the late reply @Arthur but I started my Christmas holydays some days ago, I hope that the problem is resolved.
Merry Christmas everyone.

Hello everyone, I recently installed SofaPython3 in my sofa version (20.06 on Ubuntu 20.04), so I am building my first simulation in python3 and i have difficulties into code the Python controller.
I already read this interesting topic on the forum, and I understand that many things changed, like the event commands(and thi is clear) and also the…[Read more]
Pasquale94 replied to the topic Question about Neo-Hookean Strain Energy function implemented in Sofa. in the forum Using SOFA 4 months ago
Hello @nicklj !
Thank you for the answer.
Yes Indeed from coefficients that i obtained in Abaqus i made the transformations that you mentioned.
In this period i noticed that i made some stupid errors in Sofa parameters convertions.
Now i correct them, and the two Fem simulator, Abaqus and Sofa, for the design that I am trying, gives the same…[Read more]
Pasquale94 started the topic Question about Neo-Hookean Strain Energy function implemented in Sofa. in the forum Using SOFA 5 months, 1 week ago
I am implementing Soft robotic design models with Neo-hookean constituve laws.
I derived the model data, from experimental data ( tension and compression test) in Abaqus, and I deriverd from curve fitting the constitutive parameters, and the constitutive law result a Neo-hookean one.
So i tried with the same parameters, and the…[Read more]
I resolved by my self, putting in the CMakeLists.txt of src folder the following line :
option(SOFA_BUILD_METIS "Compile Metis Library" OFF)
I close the issue, for someone is building the 20.06 version can be useful.
Hello everyone, I am building the new sofa version that you posted in the Sofa website, the 20.06.
But, when I configure the project in Cmake-gui It don’t found the metis library, this library is very importat fot Sofa SparseLDLSolvers but is also a dependencies for Soft Robots plugin.
How can solve this issue?
This is what i get fromm…[Read more]

I know the topic is old but, I too was searching a solution to impose a sinusoidal force field to my project, for this reason I read this topic.
Anyway, I find the solution that can solve your issue @Nasim, I wrote the controller in this way:
Yeah I am able to code in C++, but I don’t know pretty much of SOFA API, because is few months that i use it, and now I am too busy to dedicate time to this
Anyway, in Sofa there is already a command that create the colour map, so I think that the function have to be similar to ‘computevonMisesStresses’ and ‘StressperNode’…[Read more]
Hello, I saw a little bit the codes TetrahedronFEMForceField.h and TetrahedronHyperelasticityFEMForceField.h.
In the first one there is this function:
void computeStrainDisplacement( StrainDisplacement &J, Coord a, Coord b, Coord c, Coord d );
that is defined in the TetraHedronFEMForceField.inl. Anf I don’t understand how (or if it is possible)…[Read more]
