Molecular Modeling Software

The Chemistry Unified Language Interface, habitually abbreviated to Culgi, is a modeling platform that incorporates all well-established computational methodologies and theories, and moreover includes all essential modeling techniques. Scientific areas which have informed Culgi’s layout and construction are:

  • Chemical informatics
  • Chemical engineering thermodynamics
  • Quantitative structure-activity relationships
  • Molecular simulations whereby parameters are assigned automatically. These kind of simulations produce results both on atomistic and on coarse-grained level.
  • Quantum chemistry
  • Molecular Database properties
  • Molecular Library design and screening
  • Interface integration (to provide accessible graphic and scripting editors)
  • Workflows and parallelization


Culgi’s algorithms are designed to run both on high-performance parallel supercomputers and conventional desktops, laptops and workstation clusters. The platforms that support Culgi are:

  • Windows 10
  • Windows 8
  • Windows 7
  • Windows Vista
  • UNIX
  • Linux


Culgi has a yearly release cycle.
