Molecular Modeling Software

Culgi licensing is tailor-made for each customer to give cost-effective and flexible options. We offer different commercial license types for industrial or academic partners, for individual or network use, for long or short time. Our Free Trial License allows new users to test the Culgi software and to make the best decision for their research.

The Culgi is a general purpose modelling platform including all relevant chemical modelling tools from molecular representation to continuum level.  Don Computing has the exclusive distributorship deal to distribute in ANZ

Culgi programs help designing formulations for emulsions for their optimal use in:
Enhanced oil recovery/ Emulsion breaking/ Petroleum transportation/ Re-activation of clogged wells
A comprehensive molecular representation of petroleum will lead to increased oil production, cheaper and cleaner transportation and efficient refining processes. New computer aided technologies based on rigorous chemistry and thermodynamics are needed to improve the refining processes and to complete the current lumped models.

Culgi consists of a suite of modeling and simulation algorithms from both thermodynamics and informatics, within a unique common interface. Our molecular modeling library includes all well-established simulation methodologies, covering a broad range of length and time scales:

• Chemical informatics with wide range of molecular descriptors

• Chemical engineering thermodynamics (UNIFAC and COSMO)

• Engines for quantitative structure-activity relationships (QSAR)

• Dynamic self-consistent field methods (DDFT)

• Group contribution methods

• Particle based simulations (MD, MC, DPD), with automated parameter assignment

• Quantum chemistry interface (NWChem, MOPAC)

• Automated fragmentation / parameterization for library design and screening

True multiscaling is enabled through novel hybrid modeling algorithms and versatile mapping tools. All these modeling tools can be connected and distributed over workflows.

Current release: Culgi 9.0.0.

Platform Support: 32-bit Windows 7, Windows Vista and Windows XP Professional SP3, and 64-bit Windows 7 and Windows 8, UNIX and Linux.

Performance: Culgi algorithms are designed to run on high-performance parallel supercomputers as well as on conventional workstation clusters.
