Multi-resolution SPH in CRM terrains

[Dan Fenn]

I'm looking for ways to increase the SPH particle resolution for my CRM terrain in a computationally-feasible manner, and I came across this paper:

A Consistent Multi-Resolution Smoothed Particle Hydrodynamics Method

https://www.sciencedirect.com/science/article/abs/pii/S0045782517305315

This is exactly the kind of thing I was looking for. The publication date was 2017, so I was wondering if any of this was ever incorporated into Chrono. I haven't seen anything in the code that suggests this multi-resolution capability exists, but I'm also not an experienced user.

Thanks for any input.

Hello Dan,

It was implemented but later removed (not sure for what reason, I was not here then). Your best bet to increase the SPH resolution but still have reasonable computational performance would be to use Active Domains and lesser frequency neighbor search.
