The stable version v2.3 of the relativistic and electromagnetic molecular dynamics simulation has been created for nano-scale kinetic phenomena, and is released in November, 2024. It is an explicit molecular dynamics code keeping the Courant condition, with parallel MPI version 3 and Fortran 2003. The product of current and longitudinal electric field is used to separate EM and ES effects with high accuracy. The long Z-axis in the central coordinate space is parallelized for many processors (note: the original numerical code was published in CPC 2019, also an article in ArXiv of the same April). The post-processing programs and PDF graphics are very good for learning this code.

The stable v2.1 version of molecular dynamics simulation code of the relativistic and electromagnetic technique for nano-scale phenomena is released as November, 2024. It is an explicit molecular dynamics code keeping the Courant condition, with parallel MPI version 3 and Fortran 2003. The product of current and longitudinal electric field is used to separate EM and ES effects. The long Z axis in the central coordinated space is parallelized for many processors (note: the mixed y and z coordinates different from the original 2017 published in CPC 2019, are fixed). While others of the post-processing programs and PDF graphics are the same as before.

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.

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).

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.
