[SOLVED] How to implement mechanical resistance in a simple model

[Louise]

Hello everyone,

I’m using sofa for the first time and I’m trying te create a simple block that deforms because of gravity, I used the youngs modulus to add elasticity in my model. I’m planning to do this experiment in real life by making a block of pudding. My problem is that the model keeps moving when I simulate it and I want to know if there is a way to add mechanical resistance to my model.

Thank you already for reading this!

Hi @louises

Welcome on the SOFA forum!
What you are looking at is an equilibrium state.

In dynamics, you will have such oscillations (usual example given is a pendulum) and a solution to get a steady state is to add numerical (Rayleigh) damping. However, this does not represent the physics and might create deviation between your simulation and your experiment.

Using a static simulation, you will end up with the proper equilibrium state. Take a look at the example: examples/Components/solver/StaticSolver.scn

Cheers,

Hugo

Thank you! This has solved the problem for me!
