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!

hi leverkin,
did u solve your problem in fluent 'dasac failure at temperature'.
I too got the same problem.If u got the solution please help me.

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.
