Description

Dear researchers, thank you very much for publishing the simulation code!
I have a question conserning the formula for the Rayleigh number in LH2Simulate.m file (for example, in line 409):

Maybe I have missunderstood something, but could it be possible that in this equation the kinematic viscosity should be squared? I found the following equation for the Rayleigh number:

Please correct me if I am wrong.
Thank you very much in advance!

Research direction

Start in LH2Simulate.m around line 409 and compare the implemented Rayleigh-number formula with the referenced equation and surrounding variable definitions. Review the existing comment discussion before deciding whether the expression is incorrect; done means the formula is confirmed or corrected and the result is documented or validated in the simulation.
