Hi @Hugo,

Now I need to do a simulation experiment of virtual and real combination of robot grasping.Do you know how to interact with hardware?
My hardware can communicate with the host computer through usb.Does sofa have the function of serial port communication?

Hi @Hugo

I am very sorry to reply to your help so late.There are some problem when I sitimulate in SOFA.

1. Do you mean that I need to model separately the pneumatic model and restriction line model if I want to sitimulate a pneumatic structure with restriction line in SOFA?
2. How can I get the model indices when I use AttachConstrain ?I am confused with indices.What is indices? Are there some methods to get the model indices?
3. Do you have some example of a combination of two models?

I hope to get your reply.

Hi @Hugo,
I appreciate your reply.
The first problem is how to set a curve in SOFA,just like using CylinderGridTopology to set a cylinder.
With your help, I have some understanding of the use of sofa.But as you said TetrahedronHyperelasticityFEMForceField can sitimulate anisotropic material,why did you point out again that this dose not exist in the core of sofa ?
Finalily, do you konw how to change the cylinder (used CylinderGridTopology to set) to Tetrahedral Set Topology? Because when I use TetrahedronHyperelasticityFEMForceField ,there is existing a ERROR: object must have a Tetrahedral Set Topology.

I hope to get your reply.

Hi @Hugo

I appreciate your help.And I will try to use the hyperelastic laws to sovle my problem.But I have a few other problem:
1. Can I use sofa to draw curves?Because I might want to put a ring fiber on my device to limit its Dofs.
2. What can I do to change the material of an object,except to modify the FEM analysis parameters?
3.What should I do if I want to get a diagonal box?Becauese I can only define the minimum position and the maximum position.
4.Where can I find a detailed description of the sofa tool?While there’s official website for some tools have detailed narration (for example BoxROI), but still has a part is no (for example TetrahedronHyperelasticityFEMForceField, I don’t know what the input parameters, and what can modify).

I hope to get your reply.

Hi @Hugo
I use TetrehedronFEMForceField to do FEM analysis.
