    Simulation Calculation Service

    Material simulation calculation platforms

    • Materials Studio
    • Materials Studio material simulation software takes the visual window interface as the core, and mainly includes quantum mechanics module, classical molecular mechanics, dynamics module, mesoscopic dynamics module, Monte Carlo method module, quantitative structure-activity relationship module and crystal morphology and structure prediction module.

    • VASP
    • VASP is a complex package for performing ab-initio quantum-mechanical molecular dynamics (MD) simulations using pseudopotentials or the projector-augmented wave method and a plane wave basis set.

      The main functions of VASP include:

      Structural propertiesLattice structure parameters: bond length, bond angle, lattice constant, atomicposition
      Electronic propertiesElectronic structure: energy level, charge density distribution, energy band andelectronic density of states, electron local function
      Mechanical propertiesBulk elastic modulus and elastic constant
      Dynamicsand relaxationAB initio molecular dynamics: Born-Oppenheimer molecular dynamics
      Ion relaxation methods: Quasi-Newton, conjugate gradient, Damped molecular dynamics
      Latticedynamic propertiesPhonon spectrum, etc.
      MagneticColinear and non-collinear magnetic
      Spin-orbit coupling
      Optical propertiesCalculation of dielectric tensor by RPA and TD-DFT
    • Gaussian
    • The main application object of quantitative simulation based on Gaussian software is isolated system, that is, the structure and properties of aperiodic structures are calculated and analyzed. By using the calculation results of Gaussian, combined with appropriate analysis methods or analysis software, we can get a lot of information about the energy, electrostatic potential, molecular orbital, electronic structure, vibration form, excited state and so on, or can be used to find the transition state and reaction path of the reaction.

    • Discovery Studio
    • Discovery StudioTM (DS) is a professional molecular simulation software for life sciences. The current main functions of DS include protein characterization (including protein-protein interaction), homologous modeling, molecular mechanics calculation and molecular dynamics simulation, structure-based drug design tools (including ligand-protein interaction, new drug design and molecular docking), small molecule-based drug design tools (including quantitative structure-activity relationship, pharmacophore, database screening, ADMET) and the design and analysis of the combined library.
