In chemistryProperties, we need to define thechemistrySolver
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 !!! |

ODE solvers are created thinking stiff system in mind.
