Hello,
I am currently attempting to run a particle simulation reactingParcelFoam. At a specific time in the simulation, I encounter the following error message:

Courant Number mean: 2.643286466 max: 3.554372284
deltaT = 0.000508
Time = 1.00076

[x:6083] *** An error occurred in MPI_Recv
[x:6083] *** reported by process [2282029057,2]
[x:6083] *** on communicator MPI COMMUNICATOR 3 SPLIT FROM 0
[x:6083] *** MPI_ERR_TRUNCATE: message truncated

[x:06076] 2 more processes have sent help message help-mpi-errors.txt / mpi_errors_are_fatal
[x:06076] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages
When running the simulation in serial, the following warning message is displayed during each time step:
Quote:
--> FOAM Warning :
From function void Foam:article::locate(const vector&, const vector*, Foam::label, bool, Foam::string)
in file particle/particle.C at line 493
"Particle initialised with a location outside of the mesh."
I am unsure if the two are linked however. The warning described above occurs during simulation cases without any errors.



I am running on OF6, Ubuntu 18.04.6 LTS with 32GB RAM. As can be seen above the error message, the simulation ran for a significant amount of time before encountering the problem.


Any ideas as to what might cause the error are greatly appreciated.
