true SDC detonation tests are failing

Open zingale opened this issue 3 years ago • 1 comments

We have 2 true SDC detonation tests in the test suite (one 2nd order and the other 4th order). Currently, they have VODE errors after 12 - 14 timestep.

This is running with: inputs-det-x.sdc.test

It's interesting to note that even the Strang solver will crash after 29 steps with "advance unsuccessful" after trying the CTU update (note: this is because retry is turned off).

I think we need to revisit the Jacobian now that we have things with e as an independent variable in the reaction network.

closing this, since all of the true-SDC solvers have been updated. If we care about doing detonations with true-SDC, then we can look at the issues at that time.
