Simulation software Simcenter Culgi

programmingmodelingparameterization

Overview
Simcenter Culgi is a multiscale computational chemistry software for materials and formulation development. It enables virtual screening and design of novel materials and formulations by linking quantum chemistry, molecular dynamics, coarse-grained models and mesoscopic/phase-field methods in workflows that span from molecular interactions up to macroscopic properties. The product supports a digital-materials approach across the full product lifecycle (inception, process development, logistics and market analysis).

Key capabilities

• Multiscale simulation chain: quantum chemistry (ab-initio), atomistic molecular dynamics, coarse-grained modeling, mesoscopic/phase-field modeling and continuum-relevant outputs.
• Automated coarse-graining and mapper/parameterization workflows to accelerate creation of coarse-grained models from atomistic descriptions.
• Integrated quantum chemistry support (includes integrations such as NWChem) to derive physical parameters and chemical insights at the electronic level.
• Comprehensive molecular dynamics toolset with scripting and workflow automation for force-field development, reactive and charged systems, and high-throughput studies.
• Mesoscopic modeling (phase-field) to predict morphology, phase separation and mesoscale transport phenomena for polymers, blends and complex formulations.
• High-performance computing support and Design of Computations paradigms for screening many formulations or polymer combinations at scale.
• Graphical programming environment and Python scripting for customized workflows, automation and reproducible pipelines.

Applications and targeted domains

• Pharmaceuticals: formulation screening, interaction prediction, excipient/drug compatibility and stability assessment.
• Cosmetics and personal care: design and optimization of formulations, stability and performance prediction.
• Specialty chemicals and solvents: screening of greener solvents and formulation optimization for sustainability.
• Energy storage and membranes: polymer membranes for batteries and fuel cells; durability and transport properties evaluation.
• Oil & gas: improved chemical mixes for enhanced oil recovery, demulsification and related multiphase problems.

Selected technical strengths

• Automated parameterization and fragmentation routines to reduce manual force-field development effort.
• Coarse-grained methods (Brownian, dissipative particle dynamics and automated mapping) for mesoscale sampling and long-timescale phenomena.
• Equilibrium detection and runtime optimizations to accelerate long simulations and reduce turnaround time.
• Ability to handle complex mixtures, interfaces and micro-/nano-structured systems (e.g., microemulsions, liposomes, polymer blends).
• Support for realistic process-relevant properties and screening workflows to link formulation design to manufacturing and logistics considerations.
