Hello users,
I use these physics (air entraiment, bubble and phase change, density evaluation, drift flux) in flow3d to simulate the air effects within sea wave. The simulation crash with this error "dbug print from mrtcal - negative tn, rho, or rhoe"
Can you help me, please?
Thank you

you probably do not need bubble and phase change model. there are no large bubbles (larger than cell size) in the wave and certainly no phase change. For the drift-flux mode, what bubble (particle) size do you define?

It was 0.0 (default value), but now I run a new simulation with 0.01
