A particle-in-cell (PIC) simulation tool, OOPD1, is wrapped in the Python programming language, enabling automated algorithmic optimization of physical and numerical parameters. The Python-based environment exposes internal variables, enabling modification of simulation parameters, as well as run-time ...
This runs the driven cavity problem using the transport velocity formulation of Adami et al. The output directorycavity_outputwill also contain streamlines and other post-processed results after the simulation completes. For example the streamlines look like the following image: ...
The simulation will reveal a surprising and robust tendency for chaining of disks along the director axis which seems to contradict the chaining in aangle with respect to the director axis as predicted by quadrupolar elastic interactions in two dimensions45. This turns out to be a result of a ...
Run a simulation on your machine¶ The first step for any simulation is to create a new directory to contain all the simulation inputs and outputs. Otherwise, the many generated files would pollute your current directory. # Make a new folder and go inside ...
Let’s make the first step to introduce parallel processing of all the patches. We will use several OpenMP threads in a single MPI process. Use a good patch configuration found in the previous step: 8x8 patches. The single patch simulation is maybe slightly faster but it cannot exhibit any ...
Smilei is an open-source, user-friendly electromagnetic particle-in-cell code for the kinetic simulation of plasmas. Co-developed by physicists and computer scientists, it is designed for high-performance on the most recent supercomputing architectures. Smilei is applied to a wide range of applicat...

Red lines are populations selected at a higher temperature; black lines correspond to populations that were not heated between passages.cComputer simulation of virus fitness distributions with different degrees of particle thermostability and ...
Warp is a multidimensional discrete-particle beam simulation program designed to be applicable where the beam space-charge is non-negligible or dominant. It is being developed in a collaboration among LLNL, LBNL and the University of Maryland. It was originally designed and optimized for heave ion...
