[LA-SiGMA-funded] Joint Sid Fuchs Mechanical Enginereing Seminar Series and LaSiGMA Seminar: Steve Plimpton - Schedule and Info

[Dimitris E Nikitopoulos]

Dear Colleagues,

 

Below the signature line of this message you will find the details of
the Adobe Connect Meeting (including the link) that will enable you to
"beam in" to Steve Plimpton's seminar.

 

Please "beam in" from a central designated location at your institution
to avoid taxing the bandwidth with a large number of individual
participants. This can be coordinated by your local support
staff/experts.

 

I hope all works out well.

 

Best

Dimitris

Summary:

Seminar Title: Multi-scale modeling via particle methods

Abstract: I'll describe two approaches to multi-scale modeling that we
have undertaken using our molecular dynamics code LAMMPS. The first is
to provide a hierarchy of methods for coarse-graining a model, so that
simulations at varying length and timescales can be performed with the
same code, hopefully with some overlap. In our case, we have done this
to model the rheological properties of solvated nanoparticles, in
collaboration with industrial partners. The second approach is to couple
particle dynamics to other more meso-scale methods such as kinetic Monte
Carlo models for microstructural evolution in solids. This work is more
preliminary, but I will illustrate how it can be done. Finally, I'll
highlight a trend in all-atom molecular dynamics modeling whereby
potentials are growing both more accurate and more expensive over time.
