Hello Hugo,

I highly support the idea of the SofaAward. So anyone using Sofa don’t hesitate to submit your work to the award. It can be big plugins, tools, framework or something more “simple” like the best sofa simulation you made with all the data/mesh/texture to run it.

See you in Paris.

Hi all,
thanks for your questions

at @sushil-s:
Given the error message you are reporting says that there is no runSofa application visible. This means either the compilation didn’t went well or the runApplication is not in your “PATH” (if you don’t know what the PATH is: http://www.linfo.org/path_env_var.html). To check if the compilation did…[Read more]

Hello @hugo hello @tonydelabril

I’m not very aware of the MOR plugin I think Felix or Olivier are better suited to answer.

But to give a bet I would say that the binary version is be shipped with the extra tools (including sofa-launcher) and the documentation for MOR was written for the source based version of Sofa (so taking as granted that…[Read more]

Hi @sayan, sorry to reply late, thank @hugo for the poke.

So to answer your first question, yes we are connecting physical robots to Sofa.
The simplest technical solution is to use USB->Arduino->motors. You can find pieces of explanation for this part in our tutoring web site: http://handsonsoftrobotics.lille.inria.fr/

Once you have an…[Read more]

yes 😉

Hi @shiva,

There is no “make an exe” button in the runSofa gui. This would be a nice addendum, not to hard to do, but right now there is none.

To achieve what you want to do you can:
– put the content of the .xml or a .scn or a .py as a big string in a .cpp file and use this string as the source of a scene loader. This would allows to load the…[Read more]

Hi @nicklj, hi hugo,

I will add that to my todo list.

Hi @Zahra

On my side I don’t use Anaconda and prefer to rely on pip as much as I can.
About SofaPython3. The answer is yes, it make it possible to import Sofa modules and run a simulation directly in any python interpreter (Jupyter, Spyder, python3) in addition to the embedded one in runSofa.

Regards,
Damien.

Hi MA,

Clearly SOFA is not dedicated to fabric simulation, it is a general purpose modeling and simulation framework for deformable object.

The problem with modelling is that you need to know what is the dynamic behavior you want to simulate to select the most appropriate mechanial model. If the dynamic behavior can be approximated well enough…[Read more]

Hi all,

There is also a plugin called SofaEulerianFluid 2D & 3D.
I’m not sure it is very active yet but if you try it please tell us and in all case it is probably a good starting point for fluid simulation.

Hi @nicklj,

Sorry to reply late.

My first guess with the failure to import SofaPython is that it may be because you specify the -DCMAKE_INSTALL_PREFIX=/home/liuj/opt/SOFA/master. I’m not sure to understand why you are specifying it. But this is supposed to be the location where sofa is installed and not the path to the source code.

The need…[Read more]

Hi,

If you use sofa-spm it will generate the CMakeLists.txt for you 🙂

Here is a cut & past from one of my CMakeLists.txt:

sofa_add_plugin(SofaPython3 SofaPython3)
sofa_add_plugin(STLIB STLIB)
sofa_add_plugin(SoftRobots SoftRobots)
sofa_add_plugin(SoftRobots.Inverse SoftRobots.Inverse)
sofa_add_plugin(SofaQtQuick SofaQtQuick)


Then I add the…[Read more]

Hi all,

I tend to be rather busy so forgot to reply immediately so thank for the poke,

About STLIB, Thank for the poke, STLIB is an external plugin available at
https://github.com/SofaDefrost/STLIB

It should be installed in the same way as you did for SoftRobots.

To ease installation of plugins with dependencies recommand the use of…[Read more]

Hi MA,

About mesh generation, CGAL is rather hard to use.
If you prefer it is possible to rely on GMESH for meshing.
Stefan Escaida and I made helping function for that STLIB/SoftRobots plugins.

It is undocumented feature in:
https://github.com/SofaDefrost/STLIB/tree/master/python/splib/geometric

But there is “createScene” function that will…[Read more]

Hello,

I’m glad to hear about people trying the SoftRobot plugins.
My first advice is that if you don’t need to compile your self the plugin we are now providing binary version of Sofa+SoftRobot+SoftRobots.Inverse+STLIB. They are available at: https://project.inria.fr/softrobot/install-get-started-2/download/

But if these version are not recent…[Read more]

Hi Binesh,

Thanks a lot for the video you made. It is very helpful to anyone.

Damien.

Hi Wong,

I’m not surprised there is a lot of bug in the DistanceField plugins because it is not often used. As SOFA is developed by volunteers if you know c++ and have the willing you are welcome to submit patches fixing things (https://github.com/sofa-framework/sofa/pulls), and we would be pleased to help you if needed. If you are not a c++…[Read more]

Hello Wong,

Did you made some progress on that topic ?

Hi Wong,

You can have Distance Field collisions by activating the SofaDistanceGrid plugin.
I don’t know if this plugin is available in the binary release of Sofa; If this is not the case you will need to re-compile Sofa by activating the plugin in the cmake build process.

When the plugin is on you will be able to execute the example that is in…[Read more]

Hi Fatima,

I just looked at and TetrahedronFEMForceField does not expose the stiffnessMatrix so it is not surprising it does not work.

Adding a new Data to a component is not hard, assuming you know c++ and that the data you want to expose is available in the component. I don’t know for TetrahedronFEMFOrceField so I advice you to open an issue…[Read more]
