[aspect-devel] Active tracers with AMR

Hi everyone,

I was trying to run a model with active tracers and AMR, but it crashes at
initial adaptive refinement step. This is the error that I get:

> [titan:42726] *** An error occurred in MPI_Irecv
> [titan:42726] *** reported by process [140028719661057,214748364813]
> [titan:42726] *** on communicator MPI COMMUNICATOR 4 DUP FROM 3
> [titan:42726] *** MPI_ERR_COUNT: invalid count argument
> [titan:42726] *** MPI_ERRORS_ARE_FATAL (processes in this communicator
> will now abort,
> [titan:42726] ***    and potentially your MPI job)


Here are the relevant model parameters:

subsection Particles
set Number of particles = 1e7
set List of particle properties = velocity, initial composition,
composition, initial position, integrated strain, integrated strain
invariant
set Interpolation scheme = cell average
set Particle generator name = random uniform
set Minimum particles per cell = 10
set Time between data output = 1e6
set Particle weight = 20
end

I tried the same model without AMR (refinement 5+0 instead of 4+1) and it
works fine. If anyone has any ideas on what I can try to do to fix the
problem, I'd appreciate it!

Best regards,
Lev Karatun.
