v1.7.2

The stable version v1.7.2 of molecular dynamics code of the relativistic and electromagnetic simulation for nano-scale phenomena is released as late 2024. It is an explicit molecular dynamics code keeping the Courant condition, with parallel MPI version 3 and Fortran 2003. The long Z direction is parallelized to processors (note: the mixed y and z coordinates from the original 2017 version published in CPC 2019, are properly fixed). While others of the post-processing programs and PDF graphics are the same as before.

Stable v.1.7 code

The stable version v.1.7 of molecular dynamics code of the relativistic and electromagnetic simulation for nano-scale phenomena is released as of Sep. 2024. It is an explicit molecular dynamics code with parallel MPI version 3, and Fortran 2003 is used. The Z direction is parallelized. While others of the post-processing programs and PDF graphics are the same as the v.1.5 version.

Stable release v.1.5

Stable v.1.5 version of molecular dynamics of the relativistic and electromagnetic simulation code is released. The description of the main Fortran code has been updated for these six months. While others of the post-processing programs and PDF graphics are the same as the v.1.4 version.

Stable v.1.4

Stable v.1.4 version of molecular dynamics simulation code. Description and remarks of the present code and post-processing programs are written for the packages of the code.

Stable v.1.3

Relativistic and electromagnetic molecular dynamics simulation code in the open space, @a_cnt3-3p8Ca.f03. The CGS units and real masses of H, C, Au ions and electrons are used for nano-scale phenomena. The simulation method and applications are written in README.md and at the remarks in the simulation code itself. The post-processing programs named @3ddisp.f03, @3dfdispC.f03 and @3dfv.f03, respectively, shows the space and velocity distributions plots of electrons and atomic species, with PDF plots of typically MeV energetic particles. The reference of the simulation code and physical discussions are Computer Physics Communications, vol.241, 56 (2019).

v.1.2

Relativistic and electromagnetic molecular dynamics simulation code in open boundary conditions.
Post-processing programs are attached with postscript plots of H, C, Au and electrons at suffix FT.77.
Main subroutines are explained at the top of this simulation code, and at the major headlines.
The program is under Fortran 2003 and MPI-3.2 is used for parallelization in the z direction.

Stable code v.1.1

Parallel version of the molecular dynamics simulation code for relativistic particles and electromagnetic fields. Post processing programs of high-energy particles are incorporated, for parallel and perpendicular distributions and time sequential plots of ions and electrons..
