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

Re: eddy dissipation concept
try increasing the memory for ISAT table from 100mb to around 400 mb

might help.

Re: eddy dissipation concept
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).

Re: eddy dissipation concept
When you will use Eddy Dissipation concept model?

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