Problem occurs when i upgrade from OF210 to OF231

Hi foamers,

i am currently upgrading vy version of OF from 2.1.0 to 2.3.1.
To achive properly this upgrade, i make run some test-cases to validate the nresults of the new version.

But i have a problem using buoyantSimpleFoam. Some changes have to be done, which do not look very important (syntaxic changes).
But the job doesn't run well, the time step error is increasing a lot and the job crashes.

Have anybody already been whisper of this kind of problem ? ANd have you find a solution to make the job run as well as on OF210 ?

Have a good day,
Laurent

To be more precise the main problem seems to be the calculation of rho.
On OF210 the value of rho was satying around his initial value, as expected.
But using OF231, the value of rho diverges afetr 2 ietrations and the job crashes because of a too big number of iterations.

Between the two versions, i had to change the thermo type from a hePsi type to a heRho one, can it be responsible of my problem ?

Hi,
I have the same problem. Do you find any clues?
All of my cases that used to work with older version of OF, now have the same problem with the newer version with thermodynamic properties updated (OF 2.3.1 and 2.4.0).
