Validating astrophysical simulation codes

Astrophysical simulations model phenomena that can't be fully reproduced terrestrially. Validation then requires carefully devising feasible experiments with the relevant physics. The authors describe validating simulations against experiments that probe fluid instabilities, nuclear burning, an...

Summary:Astrophysical simulations model phenomena that can't be fully reproduced terrestrially. Validation then requires carefully devising feasible experiments with the relevant physics. The authors describe validating simulations against experiments that probe fluid instabilities, nuclear burning, and radiation transport, and then discuss insights from - and the limitations of - these tests.
