CVode error while running
 

I got error messgae below while running Cantera solved CH4 combustion case. Anyone can tell me the possible reasons cause it?

Error message:

Time = 3
Solving chemistry
[CVODES ERROR] CVode
At t = 0 and h = 3.55081e-29, the error test failed repeatedly or with |h| = hmin.

CVode/Cantera can't satisfy the requested accuracy of the solution. That can have a lot of causes. But I think that a pressure of 3e14 is a bit excessive. Seems to me the solution already blew up at the previous timestep. I'd suggest writting out all timesteps. Having a look where it blew up. Think what could be the cause. Play around with intitial values, relaxation factors, check the chemical system.

gschaider, seems that I've resolved this problem.
The main reason seems to be the unstructed mesh, now I use one mesh made by blockMesh, everything seems OK.
And I changed one initial condition of p from "totalPressure" to "fixedValue", and T from "totalTemprature" to "fixedValue".
