preCICE adapter for MBDyn solver for beam elements

[Makis]

@Claudio would you maybe like to post here a summary of points that helped you go forward?

I understand that this issue is difficult to ever be marked as “resolved”, but I guess the future reader may want to also read these topics:

Question about forces at interface

Hi, I am working on a structural adapter and I’m experimenting it with some of the tutorials. When simulating something like the vertical flap with SU2 euler flow, I obtain something like the video below, which at least qualitatively looks physically reasonable: [SU2 vertical flap] Going into the data of the simulation, I recovered the data from the interface mesh and imported them together with the fluid flow. During some timesteps find situations like the one below: [status] …

MBDyn OpenFOAM FSI coupling: convergence issues

After talking to @uekerman and @Makis about the issues I found coupling MBDyn and OpenFOAM and having found some interesting cues in the discussion from IQN fails for quickly changing forces during wetting in a free-surface FSI problem, I would like to share some thoughts and considerations about my setup and PreCICE configuration. I am working on a vertical flap setup, where the structure is composed of a set of MBDyn beams and the fluid is a OF incompressible model. The forces and displacemen…
