Question about an MPI error

yushiw · July 5, 2012, 10:45

Hi, all,

I am trying to calculate pressure gradient in interFoam by adding
volVectorField gradp = fvc::grad(p);
This working fine in series but if I run in parallel, I got error

*** An error occurred in MPI_Recv
*** on communicator MPI_COMM_WORLD
*** MPI_ERR_TRUNCATE: message truncated
*** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)

I am really appreciated if someone could let me know how I can get this to work.

Greetings

Yushi

Just got it right.
I put it in a wrong place.
