I reviewed my problem again, the problem with the “swapped coordinates” was my error because I mistyped the coordinates in the precice_config.xml file. I fixed this error, and now these coordinates look good.
However, the first watchpoint file is still weird. I re-attached the files of the watchpoints.

I am using a beam element (B32) of width 0.002, length 0.004, and hight 0.09 m of rubber. I have also uploaded the files of the solid grid (Calculix/beam32) and the vtk_calc files. Besides, I notice in the vtk-files that for the last point of the beam the exported value is very small, and not physical. Can you give me some ideas on why this happens?
I have increased the accuracy in FASTEST to less than 1e-6 normalize error, and I used the parameters “50, and 10” that you suggested, but the simulation is not stable. Divergence occurs when water wets the structure.
Do you have any suggestions about these types of cases when the load changes abruptly?
