Hi there, I have recently started using PeleC for detonation simulations and I am trying to simulate a planar detonation propagation(2D). The initial conditions are showed below.

However, I often encounter CVODE errors, such as "the corrector convergence test failed repeatedly or with |h| = hmin" and "From CVODE: At t = 1.01412e-09, mxstep steps taken before reaching tout."
I referred to discussions 713(#713), reduced the CFL number, increased the allowable residual tolerance for ODE, and increased the maximum number of iterations. I also tried changing the CVODE solve type (used a preconditioned GMRES solver). The mechanism uesd is LiDryer. I used a 3level AMR according to TempGrad or pressGrad. However, it also encountered CVODE errors. Is there a way to solve it?
