eddy dissipation concept
 

hello everybody:

the reaction mechanism i used is the eddy dissipation concept model,but before the iteration,an error message occured:

it is:

error:rmap2:ddasac failure

what's the meaning of this????

thanks a lot

try increasing the memory for ISAT table from 100mb to around 400 mb

might help.

dasac is the ODE integrator. It will diverge with stiff chemistry and bad initial conditions. Follow the EDC tutorial (which starts from an equilibrium Partially-Premixed solution for the initial condition).

When you will use Eddy Dissipation concept model?

i simulate high temperature air combustion with several reaction mechanism. if i use other combustion model, it did not run well
