Me neither not an expert 😉 I usually use Paraview in the same way you described, but I thought that there might be some magic configurations I don’t know. If I learned something interesting, I’ll share it.

Thanks,

Hi @Hugo,

The setting using the TetrahedronSetGeometryAlgorithms seems not bad at all !

BTW, when you mentioned ParaView, Do you mean by selecting the volume representation from the drop box in the toolbar, or am I missing something? A brief explanation of setting steps would be helpful as well.

Thanks,

Hi Hugo,

Exactly, I was looking for this config file for the CI.

Thanks,

Hello all,

I join Thabita clarifying the current state of configuring Sofa since that we are trying it together.

As @taro has already mentioned, the compilation is fine right now. However, a run time error happens when executing runSofa.exe, and which is probably related to the qwindows.dll which can not be located! I include the complete error…[Read more]

Hi all,

It is always an interesting topic.

In a simple simulation scenario, I applied a linear tensile force on a deformable object in the direction of its main axis. Using a Neo-Hookean behavior model, I noticed that the deformation is influenced by the number and size of elements (tetrahedrons).

However, it is possible to control the…[Read more]

Fine for me. Marked as resolved!

Hi Hugo,

I see. Thanks!
This means that I have to set youngModulus in MPa. and the force in Newton.

You also mentioned:

If the file mesh you load has values between 0 and 40

Non, they are not! The shape is not necessarily translated to the origin (0,0,0). The bounding box of the cuboid could be for instance [200 100 50 , 240 130 55]. Still,…[Read more]

Solved!
Actually It should be simply :

l_forceField->d_force.setValue(initForce.getValue());

Hello minj,

You can apply a constant force field to a certain node in your mesh (let say on the node with index 5), you supply the force direction and value (for instance 7 N. in the positive direction of Y axis), I included the “arrowSizeCoef” parameter which is optional just to help visualizing the force direction.


<ConstantForceField…[Read more]

Hi Hugo,

Yes, that’s true. I forgot to include a ConstraintCorrection in the deformed object node. Now it works fine.

Thanks for the quick hint!

Hello,

I faced the same issue before with CGAL. Fortunately, I noticed that I could compile SOFA with CGAL successfully using clang
I know that this doesn’t solve the problem, but it could be a temporary solution until the issue is fixed.

I’m running:

Ubuntu 18.04.1 LTS
CGAL-4.11
clang version 6.0.0-1ubuntu2

In order to compile using clang:…[Read more]

Hello Antonin,

Thanks for the clear detailed reply. Yes, it helps!

For the moment, the collision models are static along the simulation, and splitting the mesh into 2 parts sounds a good approach.

The hint concerning “doCollisionDetection” method is also handy, I may need to implement a specific collision pipeline with an adapted narrow phase…[Read more]

Hi Zahra,

In general, you can use the python debugger pdb directly in the terminal
https://docs.python.org/2.0/lib/module-pdb.html

Or inside an IDE such as Spyder which supports pdb as well
https://pythonhosted.org/spyder/debugging.html

I hope this will help,

Hi Zahra,

I’m running Sofa v18.06. If you compile the core of sofa successfully, you should have runSofa binary in the bin directory as usual. Isn’t that the case?
