ajogajog is on a distinguished road
In chemistryProperties, we need to define the chemistrySolver

ODE and Eulerimplict can be selected here, but in ode solver, there still have a EulerSI and Euler.

the source code of ODE is in the /src/ODE/ODEsolvers
including Euler EulerSI and some else

the source code of Eulerimplicit is in the /src/thermophysicalmodels/chemistrymodel/chemistrysolver

My question is what's the difference between these two ? and in my experience, the Eulerimplicit is much faster than ODE, why?

thank you !!!
