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.

ARCHER Webinar: EIS-2 - A general purpose, high performance input deck and maths parser
Переглядів 1094 роки тому
Christopher Brady, University of Warwick The EPOCH Input System Version 2 (EIS-2), available from github.com/csbrady-warwick/EIS-2 is a publicly available Fortran "input deck" reader and maths parser well suited to high performance computing. It was developed under an ARCHER eCSE grant as a more general, higher performance replacement for the existing deck reader and maths parser in the EPOCH p...
ARCHER Webinar: CRAY Compilation Environment and Modern Fortran
Переглядів 6224 роки тому
This webinar will outline some new developments in the Cray Programming Environment and will then focus on presenting examples of the latest features from Fortran 2018 that are supported by the Cray Fortran compiler. Note that these developments are not available on ARCHER today but this webinar should prove useful to people who have access to other Cray systems or who are planning to use the n...
ARCHER Webinar: Transferring Data from ARCHER at End of Service
Переглядів 1484 роки тому
Caoimhin Laoide-Kemp and Andy Turner, EPCC, The University of Edinburgh The end of the ARCHER service is approaching and many users have large numbers of files and/or volumes of data on the service which may need to be moved to alternative locations before the end of service. Recently, we have updated the ARCHER Data Management Guide with useful advice on transferring data between different sit...
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...

ARCHER Webinar: Enabling distributed kinetic Monte Carlo simulations
amazing animation and demonstration, incredibly clear considering it's 3d
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?
Great tutorial. Anything on CG simulations?
are you sure the 2nd term of lattice command is density???
Good day! Is there any way to parallelize other three C++ variants of for-loop using OpenMP?
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); }
Awesome lectures
got good understanding of collapse of cavitation bubble
How would you output density profile for contact angle calculation?
Did no one object to cutting a dog? 😂
Thank you for the course. It is really interesting and helpful. Could you please share the code also?
Can I simulate a maxwell demon problem with LAMMPS?
UA-cam ought to ban all the remove spaming fake stuff. The only web app that works for me is Gamecrook.
Dear Sir, Can you please help me in LAMMPS project? I need some guidance.
Very helpful material! It helped me keep up with a Parallel Systems course!
.

Do not believe the fake comments on UA-cam if you don't want to fall for one of those survey scams. The one and only website that works is GameCrook.
Do we need to have programming skills in C++ for writing LAMMPS code?
No
After throwing away too much time on spam web apps, I want to save other's energy and tell you that the only website that works is GameCrook.

The video is great, but can you please make a video on how to make a data file for a polymer of 1000 beads with bond angles, potentials etc. That would be great. Thank you
I need this as well have you received a response or got the tutorial from somewhere and want to share?
Great !!!. It is really helpful and great support for the beginners. Thanks.
Did not get the trick of VACF? can you please explain it?
It was a nice presentation, can you please explain how input data file is created for a polymer manocomposite system. Any lecture regarding this will be very helpful

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.
this phenomenon was the topic of my PhD research in 1997-2001.
No Bad. Thanks though.
Sir how to download Fortran 2008
Sir can you provide the pdf for this

What is the silo footprint in the data center compared to the traditional cray systems? What about power efficiency?
Best MPI lecture on youtube. Thank you.
A very good introduction. So much info packed into it and nicely explained. Thank you for sharing.
Great Help! Thank you!
Thanks
Exellent job! Thank you for all these know-how!!!
Very nice tutorial, but would be good if future videos could somehow have the PowerPoint in fullscreen mode, rather than the instructor's view. Thanks for uploading!
can you send to me this lecture on PDF file
