Here are some of the container specs:
solver quality: 30
grid interpolator: hermite
density scale: .8
surface threshold: .108
surface tolerance: .447
color: cyan->blue based on density
incandescence: aqua->blue based on density
opacity: zero-full (spline) based on density
Let me know what other fluid specs you may need to to diagnose this effect.
Thanks in advance for any assistance.
