This is a fatal error. A particle output file (vtp) will be written
to aid debugging.

all the 9 errors are same.why?

#2

The errors are saying that particles are detected in places they shouldn’t be. This usually means that either your particles are too soft and therefore the particle time step is too large, or that there is something wrong with your geometry.

Hi, I also meet this problem. Have you solved it? I have tried to increase kn, or decrease max steps between neighbour search but finally nothing changed.
