I tested all the benchmarks. Only the benchmark of 3d dam-break model has some problems. During the process, there is a error output:
MPM main: Particle outside the mesh domain
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
This is due to that particle go outside of the computation domain?
By the way, I noticed that there can be lots of particles inside of one cell? (looks like following figure.) As before, I always define 8 particles in one cell, (and their initial position is located at the 1/4 cell or 1/4 cell size in every direction x,y,z).
Thanks a lot~
