  • Level of openness 3 ★★★
  • Document quality 3 ★★★

An open-source application for the electromagnetic field simulation based on the finite-difference time-domain (FDTD) method. Time-evolution of the electromagnetic field in the system written by 1-, 2-, and 3-dimensional orthogonal coordinates and cylinder coordinates can be calculated under various boundary conditions and spatial dependence of permittivity and permeability. The main programs are written by C++, and can be called from Python scripts.

Mm2cML

  • Level of openness 0 ☆☆☆
  • Document quality 2 ★★☆

Mm2cML is a web application that structure files can be generated from molecular model images. By carrying out three-dimensional reconstruction using OpenMVG and OpenMVS from molecular model images photographed by smartphones or digital cameras, and arranging atoms on the basis of them, users can obtain structure files (CML format) usable for molecular simulation. The simulation can be carried out on the basis of the structure examined using the molecular model in the real world.

MODYLAS

  • Level of openness 3 ★★★
  • Document quality 1 ★☆☆

MODYLAS is a highly parallelized general-purpose molecular dynamics (MD) simulation program appropriate for very large physical, chemical, and biological systems. It is equipped most standard MD techniques including free energy calculations based on thermodynamic integration method. Long-range forces are evaluated rigorously by the fast multipole method (FMM) without using the fast Fourier transform (FFT) in order to realize excellent scalability. The program enables investigations of large-scale real systems such as viruses, liposomes, assemblies of proteins and micelles, and polymers. It works on ordinary linux machines, too.
