An application for simulating microstructures of alloys based on a phase-field method. This application can treat various problems in multi-component alloy systems such as solidification, solid-phase transition, and dynamics of crystal growth. Any required thermodynamic quantities can be obtained by calculating phase diagram or by direct coupling to the thermodynamic data calculated by other application.
PolyParGen is a free web application that automatically generates OPLS force field for molecular dynamics calculations. It is possible to create OPLS-AA parameters of macromolecules such as fullerenes with complex crosslinking structures, graphene and cyclic molecules. The generated OPLS-AA force field parameter file in Gromacs format is automatically sent to users.
Provides a complete set of environments necessary for computational materials science research in the cloud. A web browser is all that is needed to start a full range of first-principles simulations, including modeling, calculation, data storage, and analysis. RSDFT is used as the engine, and the lineup will be expanded in the future. Data can be shared within a group, and structural data from other software such as GAUSSIAN and VASP can be read.
