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)" 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>)'

Actually using time 0 in other case

Creating field pDyn
Putting "p-other(p)" into field pDyn at t = "0.1" if condition "true" is true

MPI_ABORT was invoked on rank 5 in communicator MPI_COMM_WORLD
with errorcode 1.
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, Pablo |

Well, the othercase is actually the same case, so yes, same number of processors.
I also tested the same command for other simulations, with different number of processors, and the error is the same: Code:
[18] --> FOAM FATAL ERROR: [18] Parser Error for driver FieldValueExpressionDriver at "1.9" :"Foreign mesh other does not have a field named p" "p-other(p)" Does this command work with a parallel version of the Sarlacc Pit case for you? |
