janafthermo error in reactingfoam
 

Dear all//
I want to simulate a nonpremixed swirl flame with OpenFoam and used the reactingfoam solver for this

Befor i used the one reaction mechanism for methane and air combustion and get answer but now i use the DRM mechanism with 24 reaction, i use the ignition in my case and after several time step from start ignition , openfoam give janaf thermo error and temprature exceed 3000k . but i think if i can increase the temprature limition like to 4000k, after several time step i will get answer ,when used the 1 reaction temperature in some cells increase to 4500 k but in continuation temperature reduce and solution was converge

Now everybody please tell me how i can do this .

thanks
