simulation of rigid-flexible bodies

[Utkarsh]

Hello all , Is is possible to couple rigid and flexible body in chrono to simulate the deformation of the flexible body during a dynamic simulation? Asking this question because I did not find any tutorial on combining fea and mbd. Thanks.

Hello utk,

Yes it is possible to combine rigid and flexible bodies in Chrono and simulate the deformation of the flexible body during a dynamic simulation.
Take a look at the demo_FSI_Flexible_Plate - https://github.com/projectchrono/chrono/blob/feature/fsi/src/demos/fsi/demo_FSI_Flexible_Plate.cpp

Here we not only simulate a flexible body with a rigid body but also with Fluid simulated using Chrono's FSI module.

Thank you for your response.

Utk – assuming you are also interested in physical connections between a rigid MBS and FEA meshes, even better examples are demo_FEA_beams_constr, demo_FEA_beams_rotor, and demo_FEA_shellANCF_3833 (connections through constraints) and demo_FEA_beams_extrude (interaction through contact).  These demos also do not require you to build the CUDA-based Chrono::FSI module.
