Lattice Boltzmann Methods for Active Fluids
Lattice Boltzmann Methods for Active Fluids - Livio Carenza, Department of Physics, University of Bari (Italy)
Abstract: Active Matter is a peculiar kind of Soft Matter whose constituents are able to inject energy in the system at the level of the individual constituents, so that active systems evolve inherently far from thermodynamic equilibrium.
In this presentation I will provide an overview of continuum approaches suitable to model active matter in fluid environments, starting from a coarse-grained description of the active constituents and their active effect on the surrounding fluid. I will provide an overview of the basic features of Lattice Boltzmann, the numerical method implemented to integrate dynamical equations of active matter and present some details regarding the parallelization of the code used for simulations.
Furthermore I will provide an overview of some interesting phenomena arising in active matter, ranging from Spontaneous Flow to Active Turbulence.

Using non-volatile memory - Week 2 - Online course 2020
Переглядів 1334 роки тому
Persistent memory, such as Intel's Optane DCPMM, is now available for use in systems and will be included in future exascale deployments such as the DoE Aurora system. This new form of memory requires both different programming approaches to exploit the persistent functionality and storage performance and redesign of applications to benefit from the full performance of the hardware. This online...

    Hello, I'm new with you, I don't know anything about this LAMMPS, I'm going to graduate next year so I have a few questions, please: 1_ Can I use it to simulate crystal formation and growth in condensed materials? 2_ Can this program be installed on a laptop with an 8th generation i3 processor? 3 _ Can I learn how to use it in two months?

    The way you declared the member-function operator+ got me an compilation error "must have either zero or one argument". And so that got me to solution, that there should be only one parameter for that operator. Complex operator+(const Complex& c2) const { return Complex(this->re + c2.re, this->im + c2.im); }

    There are now tools to prepare LAMMPS simulations with both with ELBA and oxDNA. See the links below: github.com/jewettaij/moltemplate/tree/master/examples/coarse_grained/ELBAwater%2Bmethanol github.com/jewettaij/moltemplate/tree/master/examples/coarse_grained/DNA_models/ There's also a growing list of other coarse grained LAMMPS models here: github.com/jewettaij/moltemplate/tree/master/examples/coarse_grained Disclaimer: Currently, the ELBA example only includes the ELBA water model (a dipole), but more complicated molecules containing bonded dipoles and bonded ellipsoids should be possible as new capabilities are added to LAMMPS. (Such as the upcoming "USER-MOLC" package.) For more information, visit: moltemplate.org (Disclaimer: I wrote moltemplate.) Hi.
