Hi Dear @Hugo
zero(0) value for Rayleigh damping in euler solver make our scene very unstable and we set 0.1 for this variable.
is it OK?

Hi @pasquale94
Sorry for delay,
If you cut two tetra in shared triangle, in result you have 2 tetra with any shared triangle but it is possible to have shared vertices.
this declaration of this plane can be a collection of vertices.after that you can duplicate a vertex and duplicate shared triangle

Hi @eddhoare
if you want to reach to minimum translation between joint points you must increase K coeff to high value such as 1e+10 for rotation and translation but high value ignore some features such as collision computation . you must tune this value based on your scene.
if you want to get any delay between joints you can separate “Visual”…[Read more]

Hi @rainvector
Can you share your obj files to test your scene?
Thanks

Hi dear @pasquale94
@epernod focused deeply on topology changes in SOFA and all hints are useful,

For Implementation of remesh algorithms in SOFA you need to learn about topology modifier and topology algorithms codes in SOFA,
for 3D remesh you can declare some plane in your mesh and divide each tetra in shared triangle area.

@eliekhairallah
can you share cmake output OR cmake configure?

Hi @qwe12050
I checked your python codes and i think there is a problem in your code,
for creation of bilateral Interaction Constraint, you have to create a mechanical state same as bilateral template
i cannot see any mechanical state in your “rootNode”,
i think you must create a mechanical state in Vec3 Template

Hi @eliekhairallah
Maybe you have permission problem in your system. such as administrator privilege.
Can you test it in administrator mode?

Hi @zahra
i can’t understand exactly what do you want?
can you explain it for us with more detail

Hi @zahra
TwoWay data is useful for propagate force between 2 object, there is a example of this method.
so if you want force propagation, you must set the “twoway” data true

Hi all
In our company we established a communication with SOFA and UE
Our communication method is IPC(Inter Process Communication)
Our IPC method is Network And Shared Memory

Hi @asalimil
Do you see the “SPHFluidForceField” ?

Hi @thassyo
I think that strain value for each element or point calculate in TetraFEM codes , you can get this value from codes

Hi @zliu157
how do you move your actuator?
if you overwrite your position data of actuator dof, you ignore scene solving,
you can use a spring between actuator reference and actuator dof and move the actuator with force and finally use attach constraint with twoway

Hi @warango
Do you use the clang compiler? what is your clang compiler version?

Hi @rubab
You must set these value for dockWidget in RealGUI.cpp file
dockWidget->setFloating(true);
dockWidget->setVisible(false);


insert above codes in constructor and setFullScreen function in RealGUI.cpp file

Hi @hkomninos
Can you show me your current code?

Hi Dear @hkomninos
You can get strain vector from TetrahedronInformation inner class from TetrahedralCorotationalFEM
