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.

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]

Hi all,

To have the graphical user interface it is important to compile sofa with Qt5. It may happens that, depending on how it is installed on your systems, it is not detected.

In that case I know two options:

The first one is to stop using cmake but instead use qtcreator (you need a recent version of it) to load the CMakeLists.txt, in that…[Read more]

Hello,

There is two issues… The first problem I see is that the build system still don’t find Qt5. This is why it is written SoftRobots: Using Qt4 for some controllers which appears when Qt5 is not found. I think it is much better to make it compile with Qt5.

For the other error. Are you restarting the script in an non-empty directory (with…[Read more]

If you think that shorter is better you can also write:

state_button1 = your_GeomagicDriver.button_1


This works because the python binding search for each “MyComponent.xxxx” if there is a data with the xxxx name.

Hi outtt,

I remember that, few years ago, some have implemented collisions based on distance field representation to simulate a catheter moving into blood vessels while the vessels moving to follow heart movement. The advantage of this distance field approach was excellent performances of the collision pipeline even with a very big blood vessel…[Read more]
