Optimize Smoke&Pyro_Closed Boundaries and Gas Resize Fluid Dynamic

Recommended Posts

Trying to optimize my simulation times for a smoke simulation. 2 questions.

Question 1

On the Smoke Object node there is an option for 'Closed Boundaries'

Do these boundaries act more like walls or like windows, that is, if enabled, is the simulation INSIDE the boundaries in any way affected (like walls) or by setting boundaries are you simply optimizing your sim by clamping how far your fields will have any effect?


Question 2

I'm using a GasResizeFluidDynamic node to optimize my simulation(reduce sim times). Max bounds is set to 'Clamp to maximum and Initialization Static.

Am I correct in assuming optimization is the main purpose for this node and are my settings optimal? In the documentation it says "The Gas Resize Fluid Dynamic DOP is a microsolver used in building larger fluid simulations."
So for 'room scale' simulations, does it offer any advantage?

Appreciate any feedback. have spent a few weeks now deep diving thru tutorials and master classes on microsolvers but still lots to learn!
