Possible Bug: Penetration between face floating and solid body
Unfortunately I cannot share the simulation file due to confidentiality, but in my simulation I experienced that an object with only particles on its face penetrated a solid object. It might be a "numerical accident", but I just wanted to make others who simulate aware to check if their floating bodies behave as intended. I used normal SPH interaction (ie. no DEM or Chrono) and was very generous with number of particles. If you encounter this behaviour I would suggest you to:
- Try increasing smoothing length
- Make simulation even finer
- Lower time steps
- Enable different interaction model between floating and fixed (ie. DEM or Chrono)
I have not tested all of them yet, but these suggestions should fix any issues.
Please see this post as a service to the community and not request for a bugfix - possibly I have a mistake somewhere - I just wanted to make sure if someone else got stuck with a problem like this, they would have some ideas to go off.
