Gravity and drag force in Pyro Solver SOP (within wrapping)

Recommended Posts

Hi Everyone,


are there elegant ways to add gravity and drag to the Pyro Solver SOP?


The two forces are needed to shape dust volumes nicely. There are no options on the wrapper itself. The classic way, I'm used to, is to add a Gravity Force DOP and a Drag Force DOP at the lower end of the DOP tree. But for this I need to break the nice wrapping SideFX has built.


What are the easiest alternatives without breaking the wrapping?

 

Cheers,
Aleksej

In sparse solver gravity added by default, drag force need to add manually

Yup, before the SOP level based solvers, I tend to have the habit of adding drag forces to my simulations as well.
At the moment, the best way is the unlock the wrapper OTL and dive inside and drop the drag force SOP or alternatively, just stick to the dopnet method.
Hope this helps or someone found a way to add drag force to the new SOP level solvers.
