Hello Yvan,

Actually i noticed that this error appears only when i try to run a case which involves the C++ implementation of PyTorch (i'm trying to run an ANN inference inside the code). To test it, i tried to run a case without implementing PyTorch and with the same code configuration, and the ...

Hello,

I'm trying to run a case where mesh partitioning is required and i have the following error:

/home/cenvinzf@coria.fr/Desktop/code_saturne_coria-HuuTri_dev/code_saturne/src/mesh/cs_partition.c:2934: Fatal error.

Partitioning with METIS required but neither
ParMETIS nor METIS is available ...

Hello,

I found a function called cs_combustion_gas_yg2xye that does partially what i wanted. I managed to call it correctly in my user subroutines but it doesn't actually give me the field of values but rather what i suppose being the average.

Is it me to not have understood correctly how the ...

Hello everyone,

I am running a simple case with the combustion module on and i was wondering if there is any function present in the code to eventually convert the ym_fuel, ym_oxyd and ym_prod to the actual mass fractions of the components of the mixture (e.g., in the case of methane combustion ...

Hello Yvan,

Thanks for the tip on the temperature and the density. From what i understood you think the possible "explosion" of the pressure values may also be attributed to the wrong density algorithm chosen, am i right?

I will now try to see what happens in both cases with idilat set to 2 and ...

Hello Yvan,

I'm trying to turn off density, temperature and mass fraction calculations (those for ym_fuel, ym_oxyd and ym_prod). Should i be checking then in scalai.f90? I saw that the routine calls upon covofi for resolution of the scalars, hence i run some checks in covofi.f90 and this was the ...

Hello everyone,

I'm trying to run a simulation of a simple combustion case where after a certain number of iterations, calculation of certain fields is "moved" to a certain subroutine, that implements a neural network. The newly computed fields are then used to replace the actual CFD fields inside ...

Hello,

I actually managed to sort the bug out, as the command i was using to launch the code was not passing the correct number of processors needed to perform the computation.

Hello,

I'm trying to run a case on a multiprocess setup, but whatever the amount of processors i provide it always gives me back:

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE ...

Hello,

I'm trying to run a C++ function within a cs_user_physical_properties.f90 subroutine. Everything has been implemented just fine following how this C++/Fortran coupling is done in other standard routines, but i don't get why when passing fields from the fortran to C++ NaN values will appear ...
