The abstract deadline for #EMI2024IC ( https://t.co/I7kyG9m3BN) is one week away. Please consider submitting an abstract to MS21 co-organised by myself with @NingGuo_ZJU and @jdzhao . We look forward to meeting you in Vienna in the coming September. Thank you.

This is really amazing. Particle shape by design. Wanna simulate it but how? Checkout our timely review paper, "The role of particle shape in computational modelling of granular matter" ( https://t.co/9cBnNi0xkX)
@NatRevPhys
Thanks to a complex mathematical algorithm, these plastic shapes follow a very specific route as they roll. In fact, researchers have shown that a shape can be designed to follow almost any path you can think of.

New paper accepted - we used a modified granular temperature to quantify the characteristics of hydrodynamic dead zone of sediment gravity flow formed in front of a rigid barrier and proposed a source-sink model to describe the unjamming-jamming transition on its formation.

Considering how much time we now spend on mobile devices a day, I decided to renovate my 11-year old homepage to be mobile friendly using #bootstrap4. Hope our Z-Gen applicants find it convenient too. Any suggestions for improvements are welcome! https://t.co/vcDnMhPc6q

Speedy match! @swayzhao proposed a scalable thread-clockwise RVE parallel computing scheme - GoDEM - to match multiscale modeling w/ GPUs. GoDEM modelled footing below w/ 7.68 million RVE particles in 33 mins, 91 times faster than parallel CPU computation. https://t.co/DcugIQNdSg
