[SOLVED] High_number_soft_fem_discretized_shapes

[ewpostek]

Dear All,
I am new to SOFA. I found it a few days ago. I have seen the figure
with a few octopuses.
Let me ask, is it possible to work
with system of about 1000 independent shapes (irregular but rather convex)
that are discretized with 3D finite elements (tets) and
to calculate the stresses in them ?
The loading is self-weight and forced movements (displacements, velocities)
of some of the shapes.

best regards, Elek

Dear Elek,

I guess you are referring to the article “Volume Contact Constraints at Arbitrary Resolution”. For more information about the paper itself, you can find it here and if you have any question about it, do not hesitate to contact directly the authors.

If your question is : is it possible in SOFA to work with volumetric independent shapes and computing their stress, the answer is yes. But, then you need to be more specific about what you want for material laws, for collision detection and response algorithms.

Best,

Hugo

Hi @ewpostek,

Was my hints useful?
Do you need anything more on this specific topic?
Best,

Hugo

Hi Hugo,
Yes, it was very useful information.
Further questions, more specific, may arise
in the course of further work,
best regards,
Elek
