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 ...

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 out...

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 field...

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: invoking...

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. T...

Hello, How can i access it then? Beacuse in post-processing i can see both "Normal_stress" and "Stress" as boundary fields and i think the boundary_stress field you are mentioning only refers to "Stress". Eventually, if i have to evaluate it sohuld i refer to the user e...

Hello, I'm trying to run a calculation in which i try to couple ANN resolution for certain fields with the standard numerical resolution and i need to collect certain data every n time steps. One of them is the measure of the normal stress (that i can easily collect during the postprocess phase) whi...

Hello Yvan,

Actually i did manage to find which was the mistake, it related to my C++ implementation of the neural network. After debugging it, now the code is actually running smoothly, giving back all of the needed output files.

Thanks for the help and regards,
Francesco

hello, I do run the code from an ssh connection since i have no access to the machine at the moment and is a standard Ubuntu machine. When adding the --initalize option i actually have the run_solver and the cs_solver executable files (attached here), the following is the output of "ldd cs_solv...
