Hello all,

I'm using version 6.0.0 of CS and I have an error with the initialisation of a scalar in my field. I would like to transport Yi (mass fractions) and I have 11 species . My 11th scalar, yN2 should be initialised to 0 in the all domain, like others Yi scalars, but I found that the finial value reach -4.258 in all the domain. And adding a clipping immediately stop the program at initialisation.
I tried to force the initialisation to 0 with cs_user_f_initialization but it don't work (I tried for others Yi to test it and it worked fine for them).
Is the 11th scalar used in CS for something ?
I attached the setup.log file for help support.

Thank you for your time,
Best regards,
Camille B

Hello,

Without more info on your setup, and at least the setup files other than the mesh, it is hard to guess.

Best regards,
