Efficient sensitivity trick for ignition delay times about reactionmechanismsimulator.jl HOT 7 OPEN

So currently I don't think the adjoint sensitivity analysis is optimized enough to run something that big...I had difficulties with even with the ethane mechanism at Constant V. This could be implemented now perhaps on the H2 mechanism, but I think larger mechanisms will need #51.

Got it. I will try the H2 mechanism and post the results here.

What are the challenges for the ethane mechanism?

from reactionmechanismsimulator.jl.

It's just slow, I'm not sure about the H2 mechanism performance either for Constant V. Things should get a ton better with #51, currently we have to evaluate the full derivative function for every element of the gradients instead of a fraction of the involved reactions twice.

For curious, where the test model "../src/testing/superminimal.rms" comes from?

from reactionmechanismsimulator.jl.

It's the simplest RMG example, it's not an accurate mechanism, but it's fast to generate and simulate, which makes it great for testing things.

@jiweiqi Do you have a minimal example of doing these sensitivitiy anlysis?
What is the most efficent way to get "index of ignition"?
