After re-reading that paper, I updated (only) the parameter labels on the OTL above.

So:
Elastic Modulus - the strength of the elasticity effect

Plastic Yield Limit / formerly Gamma - the strain limit at which plastic flow occurs. A high value means little plastic flow (fluid is mostly elastic and always tries to return to original shape), low value means plastic flow can occur when norm of the strain matrix (think total deformation) is above this limit.

Plastic Flow Rate / formerly Alpha - how quickly the fluid will flow when strain is beyond the yield limit. A low value (or zero) will imply mostly elastic behaviour no matter the yield limit; a high value means the fluid will flow quickly once past the plastic yield limit.

Thanks a million for this asset!! I have used this in my project at Bournemouth University..Do check it out

I had some tracking issues hence the jitter..but H12 is awesome! Thanks again!

Great work, Pari. That looks awesome!

Thanks!

Great use of the tool! You really inspired me

I am really glad you liked it !

like it , Pari . Congrats !

great thread! thanks for the valuable info.
Regarding the gas sand forces dop, could anyone explain how to use that to achieve a sand sim?

Thanks again

Really Excellent tips and files in this thread, results are gorgeous!

Uploaded a little video testing the parameters here:

Glad I found this thread as well.

Learned a lot. Finally got the sand forces working decently. Just swap it out for the strain forces. Needs a lot of tweaking though. and it seems to explode sometimes.

This node is a tricky one.

Thank you all.

I got this annoying behavior also. (particles exploding)
it's happening only when the sim has low particle separation. (highres)

I had the pleasure to watch mr. tonks dvd
My setup is basically the same workflow.

To exemplify, here's my exploding case.
I'm using 450k particles, substeps in flip solver min 2, max 4.

The first sample has no elasticity applied..
