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:

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? |

To be honest: I haven't tried.
