Granular question
Posted: Mon Mar 30, 2020 2:06 pm
Hi everyone,
Description: I have a dam, made of sand which I want to interact with a fluid.
And I want to keep the dam's shape until the fluid touches it... trying to simulate the erosion.
There are two domains - one for the granular and one for the fluid and the interaction works perfect, but...
The dam doesn't keep its shape. It starts reacting on the gravity as soon as the sim starts.
I tried all kind of parameters to keep the dam in shape as long as it takes until the water get's in touch.
Domain granular parameters:
Res 1000
Density 1000
Interprenetation 1
Friction 0.7
St. Friction 0.9
Compactation 0.25
Damping 3
Dyverso settings
Min and Max substeps 8
Iterations 40
I want to be the sand stable like wet sand and only reacts on the fluid... any ideas?
Thank you very much
Rue
