Hi friends,

Does anyone know how Gas Sand force microsolver should be used??
I have attached it to the flip solver and particle fluid solver but I have not seen any change.

I really appreciate any help you can provide.

Hi and happy new year,

You can use sand solver by unhide some node in text editor :

opunhide Dop sandsolver
opunhide Dop sandobject
opunhide Dop sandcofigureobject

Just plug all together and sim.

Any way i dont understand why this node is hided by default and not the gas sand.

I m pretty interested to know if there is away to use this gas with flip which will be faster ( i presume)

Hi papi,

Happy new year

The Sand Solver is an interesting tool. However, the simulation is very similar to the flip solver. I am interested in using gas sand force along with flip solver because the help for this node says:

“The fluid is then broken into a series of rigid components whose strain is insufficient to separate the grains of sand. These components velocities are projected to be rigid.”

I want to use this ability for making something like a snow impact simulation…. I have used sand solver but the result is way different…

Its tricky

here is a thread on integrateing strain forces with FLIP, you pretty much have to do the same with sand. I rand some tests and it was too great of results.

might be a good start
