fails in parallel with -otherTime?
Hi all,
I've just started using swak4foam as I learned some of its greatest features during OFW8.
I am trying to obtain dynamic pressure (excess over the hydrostatic), i.e. total pressure (p) of any time minus the one of the initial time step (actually of the first calculated time step) for a parallelized case.
My command is as follows:
Code:
mpirun -np 8 funkySetFields -parallel -time '0.1:' -otherTime 0.05 -otherCase . -create -field pDyn -expression "p-other(p)"
Resulting in:
Code:

Create time
Create mesh for time = 0.1
Adding case ".", region region0 at t="0.05". Fields from that case can be accessed in expression with 'other(<field>)'

MPI_ABORT was invoked on rank 5 in communicator MPI_COMM_WORLD
with errorcode 1.
The analogous command in serial runs flawlessly.
The error does not make any sense for me. Why "1.9"? Even when using "-time 0.1" instead the error is the same one. Is this a bug or simply this feature does not work in parallel?
Best,
