Something irrelevant: the entries in `particles_->sorted_id_` are not correct after adding memory buffer particles to real particles. You can look at the `check_id` function in `test_3d_pressure_driven_poiseuille`. I know this is...

@DongWuTUM Hi Dong, I opened a new PR for contact. I'll add the deleted test cases back later this week.

> @WeiyiVirtonomy Hi Weiyi, could you sent me the reference data (and test results if it is Okay from your side) of the test cases you have tested? Including the...

## Three ring contact Reference paper: [Yang, Laursen](https://doi.org/10.1016/j.cma.2007.09.004) The big ring is modeled as a solid, while the medium and small ones are modeled as a shell. Unlike the paper,...

## Oil tank An oil tank with oil inside collided with a truck at a speed of 20m/s. The oil tank is modeled as an elastic cylindrical shell, while the...

# Hydrostatic test Test case: `test_3d_oil_tank_crash_debug` The main problem is the initial fluid particle distribution. ## No relaxation, no shell damping Strange shape, max velocity of shell~2.0 ## With relaxation,...

@DongWuTUM I still have some doubts about the renaming of RepulsionDensity and RepulsionForce. For a body named "body1" in contact with "body2" and "body3", I will need to name the...

@DongWuTUM Hi, Dong. I have renamed the repulsion forces and densities according to the type of surface contact relations. Could you take a lot at them? If it's fine with...

> Hi Weiyi, if this PR is Okay, please inform me, and then I will have a check. And for the multi-time-step solutions, I have told Prof. Hu. He said...
