Q.E.D. is on a distinguished road
Hello everyone!

I'm currently trying to run cfmesh (v1.1.1, cartesianMesh) in parallel. (MPI) But there occurs an error which I didn't manage to resolve so far. Maybe someone can help me?

The error I get is the following:

[node033:18375] *** An error occurred in MPI_Bsend
[node033:18375] *** reported by process [46912131891201,11]
[node033:18375] *** on communicator MPI_COMM_WORLD
[node033:18375] *** MPI_ERR_BUFFER: invalid buffer pointer
[node033:18375] *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
[node033:18375] *** and potentially your MPI job)

A similiar error has already been reported. (see: https://sourceforge.net/p/cfmesh/tickets/2/) But I cannot find the solution.

Thank you in advance for your support.
Arthur

Hi,

cfMesh run in parallel all the time. I guess that you are referring to MPI parallelisation.

It is not possible to understand much from what you posted here. Please provide a log file and an example that reproduces the problem (http://sscce.org/).

Regards,

Franjo
