[Mesa-users] ppisn: neutrino luminosity as a threshold for turning on Riemann solver

Hi everyone,

I've been experimenting with the ppisn test_suite. I noticed that the Riemann solver will be turned on when neutrino luminosity reaches a certain value before dynamical instability. In Merchant 2019 paper it's set to be 10d0 (10^10 solar luminosity), whereas in the test_suite it's 9d0. If I want to delay the turning on of Riemann solver and set this value to be 12d0, will the results be much different (e.g., give very different BH masses or make a PPISN event become a direct iron core collapse)?

Thank you in advance.
