Hi,
I want to use this function to give a force to one extremity of this model.
I have another question, when using
“JointSpringForceFieldRigid3d::Spring s1(0, 1, softKst, hardKst, softKsr, hardKsr, blocKsr, -3.14159, 1.57080, -1.73790, 1.47379, -2.18160, 0.00010, kd);”
how it knows the 2 objects -> ie -> Object1 and Object2
because I still have an error in execution

[WARNING] [JointSpringForceField] Link update failed for object1 =
[WARNING] [JointSpringForceField] Link update failed for object2 =
[WARNING] [JointSpringForceField] Init of PairInteractionForceField node failed!
Erreur de segmentation (core dumped)
Thank you

thank you for your reply
I use in the main.cpp file the JointSpringForceField class and I put the linear solver, my question is how to add addForce() in this program.
here is some line of code:

Dear Sir,
I tried to compile Main.cpp but I found a problem in CMakeLists.txt which seems to me that it is not complete. I mean there are some libraries that are not specified with target_link_librarie. I did not want to add all of them by hand since, I think this will take time to have them all and in the correct order. Could you please help me on this ?
I show you the error I get:

Dear Sir,

I would like to write a scene in cpp but the corresponding help link is still under construction. Could you please give me some guidelines to do it ?

Write a scene in Cpp

Hi sir,
Thank’s for your answer,
I have a nother question, I tried to compile the file “src/doc/src_exemple/example3” on Qt creator, it showed me an error at the file “scene.h“, and I didn’t found this file in sofa.

Thank’s sir

[SdAuto]

Hi sir,

I already saw the example but i want to know if i can remove a part of the liver for examination, or make a wound and suture it.

Thank you sir
