A full 3D data snapshot of plasma turbulence as simulated by the Runko particle-in-cell code. The data is visualized in Fig. 3 of Nättilä 2024. The simulation models the magnetized corona around black-hole accretion flows. The dataset includes the simulation snapshot (flds_2500.h5) and the corresponding runko configuration file (x16.ini). The turbulence is excited with a Langevin antenna and has a guide field along the z-axis. See the paper for other physical and technical details. The flds_2500.h5 HDF5 file includes 10 datasets with a 640^3 resolution: ex, ey, ez for electric field x, y, and z components bx, by, bz for magnetic field components jx, jy, jz for current density components rho for plasma density
