Hello,
which Dune version are you using? DuMux 2.12 is only compatible with
the 2.6 release not master.
I'm using DuMux 2.12 and using compatible branch.
If I use Dumux 3.0.0 I do not encouter such problem, but I would like to
fix it on 2.12 also.
I assume you follow the instructions in the DuMux handbook (3.0) and
the parallel section. Do you have more than 2 cores? If yes can you
post some time measurements over the number of cores that we can look
at? The kuvette test has only 120 cells, that's too small of a grid to
run it efficiently on many cores. Did you try the same with more
cells? Does anything change?
I follow instructions of DuMux handbook 2.12. Here some number:
I ran in /porousmediumflow/2p2c/sequential
and in test_adaptive2p2c2d.input I only changed the grid: Cells = 100 100
**mpirun -np 1 *./test_adaptive2p2c2d --> Wall time 3856 sec.*
*mpirun -np 4 ./test_adaptive2p2c2d --> Wall time 6107 sec.*
I observe such behaviour on both versions 2.12 and 3.0.0.
Kind regards,
Lorenzo
