Hello dear people,
I am recently simulating a problem with a large number of reactions and i keep having this message. Does anyone know what that means? The results that i am getting are far from realistic. Thanks in advance! |

I think "dasac" means "differential algebraic sensitivity analysis code".
But that doesn't really helps...  If you are modelling reacting flow: try reducing the highest activation energy of your reactions by a factor 1e+6 or more... That helped me... so far... |

Please try to check the material properties in reacting flows, particularly for density. This occurs due to sudden increase in temperature of the domain beyond 5000 K.
