Chrono issue with floating and tank interaction
Hello,
I am using the Project Chrono coupled with DualSPHysics to simulate floating bodies in a straight channel. At some point of my simulation, some blocks stick to the bottom face of my tank and don't move anymore. It seems like there is a gap between fluid particles and the bottom face of the tank that creates this space where floating bodies can stay (see screenshot). Is there a way to avoid this issue ?
I tried changing the allowed collision overlap in a range between 1 and 0.01 but it didn't fixed this issue.
I am also using the relativeweight parameter to keep the proportion of body immersed close to reality.
Thanks a lot for any comments or advices!
Regards

You probably need to increase resolution by quite a lot.
When you use Dynamic Boundary Condition, a gap between fluid and boundary particles will occur - lowered by increasing resolution.
Relativeweight is fine, you can do it how you like, but it is better to use a specific mass in my opinion.
Collision overlap will not change that much too my knowledge if the resolution is too low.
Kind regards
Please, check that initially the objects are not so close to the bottom
Try different cases with objects at different initial distances from the seabed
