Hello,everyone!
I have read《SU2-NEMO: An Open-Source Framework for High-Mach Nonequilibrium Multi-Species Flows》 and would like to try to reproduce some simple examples.

The first is the zero dimensionnal thermalbath using N2 gas model. I tried to solve it with NEMO EULER, but I found a strange problem.

The result about Tve and Ttr is very similar to the picture in the article，but the N2 massfraction is a little higher than the convergence value in the article. My N2 massfraction convergence value is 0.7787, while the convergence value in the article is around 0.65.

The calculation of Tve and Ttr is related to the source term in the eve equation, the source term in the eve equation is related to wdot1 and wdot2. So the mass fraction and the temperature should be coupled together? Why is the temperature correct but the mass fraction wrong?

Thank you in advance for your time and consideration. I truly appreciate any insights or advice you may have to offer.
