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 ...
You should obtain a map of the simulation box with one distinct color for each memory region (i.e. each MPI process). There are 16 regions, as we requested initially. You can see that these regions do not have necessarily the same shape. Now plot the number of particles in each region...
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: ...
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 ...
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...
Based on the results of our simulation, we chose a jump-distance distribution analysis36 to extract diffusion coefficients from our experimental videos. As an experimental verification of the diffusion coefficients obtained in this manner, we again made use of streptavidin attached to a membrane via ...
In the MC simulation, we observe a chaining of the disks along the director axis of the nematic needle phase, see Fig.1b. This chaining indicates a strongly anisotropic directional attraction caused by the hard needles along the director axis. The chaining axis coincides with two elongated zones...

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 ...
