Phoenix FD 4.0 for Maya - Adaptive Grid Clipping

[ChewyPixels]

I'm very new to Phoenix FD so I could use some guidance as to what recommended settings I need to adjust to get rid of the clipping in the adaptive grid. You can see the grid shrink towards the end. There is an "Expand and Don't Shrink" setting that I'm just now seeing. Is this the optimal way to work or should I adjust my Threshold and Extra Margin settings? Here's the link to video:

Here are the settings that I used for this sim:

Hey, yes - Expand and Don't Shrink would be what you need. In this setup, since the smoke dissipates, near the end of the simulation it starts to drop below 0.005 at the borders of the sim, and this is why the grid contracts back.

Excellent! I will give that a try. Thank you.
