FLIP Detailed Collision

[djwarder]

Hey guys

I'm doing a sim where some FLIP fluid collides with a ground collider & spreads into the grooves between some pavement slabs. However I don't seem to be able to get the SDF to be fine enough for this resolution of collision. Instead I'm thinking of having particles move along the lines & then get the fluid to follow them but not sure how exactly to do that or if there's a better way. Any ideas please?

Cheers

Dan

can you scale everything up then scale it back down post sim?

how are you creating your sdf

is it in dops?

maybe try isoofset on geo and write out deatiled volume sdf representation of you object

it helps for complicated shapes

Cheers for the advice guys. Have tried both approaches & think the best thing would be to have custom SDFs as suggested, but for each slab perhaps. Worth a go anyways I guess, just to see if that gives the look I'm after.

also make use of -/+ offset of sdf

so you can control interpenetration better

in case like this they can probably sink a bit in fluids i mean

as you wont see under side i imagine

so you dont get them floating above pavement

good luck

once you read sdf back in be sure to switch off volume based collision box

it gave me some headache
