Hi @daserk,

Sorry for my late response.
I have some questions.
When I read the output I see your problem is related to libGL. Did you install it?

What is the output of these commands.
1. docker run $extra_run_args $image runSofa
2. docker run $extra_run_args $image runSofa -g batch -l SofaPython -n 100

In Sofa, you also have the headless option (See https://github.com/sofa-framework/sofa/tree/a1ad067766b804b2985db227ac41bb504098a6d6/modules/SofaHeadlessRecorder for more).

Then you can generate the output videos of your simulation the only downside is that your simulation is not interactive

Hi @daserk,

I am sorry, I can’t get access to your output file.
Can you just paste it here directly ?
Thanks.

Hi @julien,
I think it’s a rotation issue between these two coordinates systems (SOFA and Blender).
Export three normals Nx (1, 0, 0), Ny (0, 1, 0) and Nz (0, 0, 1) from one of the coordinate systems to the other in order to obtain the transformation.

Hi @Steph
I think the easiest way to do this is to clone STLIB from Github and add it to your path.
This way we are sure you have all the files.

Sorry for my late answer.

Hi @Steph,

What is the content of Path_to_\SOFA_v20.12.02_Win64\plugins\STLIB\python/stlib ?

Tks.

[younesssss]

Then add Path_to_\SOFA_v20.12.02_Win64\plugins\STLIB\python in your path since you want to use python2

Hi @Steph & @Tori ,

did you add the splib and stlib folder to your path?
/PATH_TO_STLIB_FOLDER/python if your are using python 2.7
and /PATH_TO_STLIB/python3/src if your are using python3.

However, some scenes in the tutorial do not work with python3.
It needs a few modifications, like swtich creatsChild with addChild and
from stlib3.scene.Scene import Scene instead of from stlib.scene import MainHeader, ContactHeader

For binairies add /PATH_TO_INSTALL/lib/python3/site-packages/ or /PATH_TO_INSTALL/lib/python2/site-packages/, and check that these folders are actually on your computer.

You can send it using a link via MEGA

Hi @momo2000, can you send your scene ?
Thanks.

Hi @momo ,
Before fix the with SparseLUSolver, change the Poisson Ratio and put something between (0.3 and 0.4, preferably start with 0.4). While I still think you can find the exact Poisson ratio and the Young Modulus of your material in the literature.

[younesssss]

Bigup to you @hugo, for the job you are doing here :+1: and for the community in general.

[younesssss]

Hi @momo2000, without having seen the entire scene I really can’t.
Inside the ElasticMaterialObject the solver is SparseLDLSolver maybe change it with SparseLUSolver.
But I just have a question, why your poissonRatio=0.27 ? (Because the smallest I use to is 0.3 for the steel).

You can have a look on this page page

Yes @hugo did it two weeks ago.
Two solve your problem @Cai, you have two options.

First: Switch SOFA v.20.06 with the SOFA master then don’t need to change SoftRobots.

Second: Keep SOFA v.20.06, but for SoftRobots go back to the version before “https://github.com/SofaDefrost/SoftRobots/pull/56” pull request witch is (a4370a7aee4d445b5435d2a14cf35d209087be56).

best,

Hello @Pasquale94

I think you must add in your .bashrc (or .zshrc) the location of your runSofa
For instance : export PATH=”/home/sofa/build/bin:$PATH”

[younesssss]

1.
The result of :
find /home/younes/travail/plugin/SoftRobotsOnTheWeb/src/tools/docker/install -name "libSofaMeshCollision*" is

 /home/younes/travail/plugin/SoftRobotsOnTheWeb/src/tools/docker/install/lib/libSofaMeshCollision.so
/home/younes/travail/plugin/SoftRobotsOnTheWeb/src/tools/docker/install/lib/libSofaMeshCollision.so.20.06.99

logic since I copy them from build/lib/

b) the command ldd /home/younes/travail/plugin/SoftRobotsOnTheWeb/src/tools/docker/install/bin/runSofa
gives libSofaMeshCollision.so.20.06.99 => /home/younes/travail/sofa/headlessGui/build/lib/libSofaMeshCollision.so.20.06.99 (0x00007f9c0a3be000)

2. The result of git rev-parse --short HEAD
0b7f88e5cb . I am using the https://github.com/guparan/sofa.git/update-headless-recorder-ffmpeg-UPDATED
