Your number of iterations is high and tolerance/threshold is quite low. Do you need that much precision ?

That may be a reason why your scene is low, especially if it does not converge to your requested tolerance, you would do all 100 iterations every time step, many of them for nothing.

Try maybe to keep them to default values (25 iterations and tolerance 1e-6 or so) and see what happen.

You should give a look at the plugin named Flexible. There are some materials for simulating musculotendon system (i.e. MuscleMaterialForceField and TendonMaterialForceField), in addition to hyperelastic materials.

An addition regarding the topic, one can look also at the class sofa::helper::vectorData to use as its name says: a vector of Data

Hi Hugo,
Yes Thomas explained clearly the concept of sml ! I did not push further in that direction but it helped me to get what was the idea behind it.

Hi Thomas,

The model description is for now generic enough for our needs, no plan to extend it further – do you have s.t. in mind ?

In the examples I saw, the files were describing rigid/joint objects, but not deformable one. Is it intended ?

Hi Olivier,

Thanks a lot for the detailed information. I will take a look at that for my Data and come back here if I stumble on a major obstacle.

Hi Thomas,

Thanks for the information.

I have additional questions regarding the topic:
– Will there be documentation detailing the language, or peeking in the code is the way to go ?
– Will it be extended to overall sofa features ?
– Will it be standardized (guidelines) ? In the case where someone wants to add extra features.

– Copy PluginExample to /sofa/v15.12/src/applications/plugins/ — the PluginExample is initially in this folder

Yes my bad, by that I mean you shouldn’t copy it elsewhere 🙂

– Update /sofa/v15.12/src/applications/plugins/CMakeLists.txt — I can’t understand what I should do, what means ‘Update’. This file initially contains sofa_add_plugin(PluginExample PluginExample)

Then everything is ok there

– Activate the line PLUGIN_PLUGINEXAMPLE — Where is this line
– Configure and finally Generate –please write me which commands I need to execute

You should do first

cd build/
cmake-gui ../src/

Then tick the box appearing on the line where PLUGIN_PLUGINEXAMPLE is written
Followed by click Configure until no line appears red and finish with a click on Generate
Finally type make in the terminal in the build/ directory

I hope this helps.

Step 2 and step 3 are not right.
– Copy PluginExample to /sofa/v15.12/src/applications/plugins/
– Update /sofa/v15.12/src/applications/plugins/CMakeLists.txt
– Run from directory /sofa/v15.12/build/ the command ccmake ../src/
– Activate the line PLUGIN_PLUGINEXAMPLE
– Configure and finally Generate

Did you copy the generated zlib.dll and zlib.lib into the windows dependency folder of your sofa source folder ? (i.e. should something like sofa/v15.12/src/lib/win32 or win64 depending for what arch you build)
Also, did you also copy the zlib.dll into the bin/Debug/ folder where your runSofa.exe is located ?

If you have done both well then I cannot tell you more except that it seems to be a zlib linking issue, and… good luck !

Cheers,

Hi Michael,
I faced this issue today by building on VS2015 on Windows10.
The issue comes from the zlib in the dependencies package. You have to find a version built with VS2015 or simply build it from sources from https://github.com/madler/zlib

Then you need to place the zlib.dll zlib.lib produced in the corresponding sofa folder. Then that should fix the link issues you gave in the precedent post.

Cheers,
Fabien
