BeamFEMForceField and BeamAdapter

[Hoangn06]

Hello everyone,

I want to verify something about the beam modeling between the BeamFEMForceField and the BeamAdapter:

• Both the 2 models use Timoshenko beam theory if i'm not mistaken?

• In the modeling documentation of BeamAdapter in https://github.com/sofa-framework/BeamAdapter/blob/master/doc/modeling/theory.md, the model contains the corotational beam model. Does BeamFEMForceField also have this corotational model or not?

• About the mass between the beam model, if i'm not wrong, the BeamAdapter compute the mass while the BeamFEMForceField can not. Why can't we add for BeamFEMForceField the command "UniformMass name="mass" totalMass="1" " for example to compute the mass?

• To add the Young Modulus/Poisson ratio if i used BeamAdapter, does i add the "BeamInterpolation" command?

Does someone know the answers to these questions?

@hugtalbot can you help me for these questions?

Thank you and have a nice day!
