Coarse-grained Dynamics Simulation Service
Coarse-grained molecular dynamics is a simulation method that enhances computational efficiency by simplifying the atomic details of a molecular system. This method aggregates multiple atoms or chemical groups into "coarse-grained beads," thereby substantially reducing the degrees of freedom. It allows researchers to study the behavior of complex biomolecules or material systems on longer time scales (microseconds to milliseconds) and larger spatial scales. CD ComputaBio mitigates accuracy errors in coarse-grained molecular dynamics simulations to within 5% through the integration of AI-enhanced parameterization, high-performance computing, and cross-scale validation.
Introduction to Coarse-grained Dynamics Simulation
Coarse-grained molecular dynamics simulation is a method that reduces computational complexity by simplifying the model while retaining the key characteristics of the system. It possesses several key features, including:
Reduced Degrees of Freedom
Coarse-graining, by mapping multiple atoms into a single particle, reduces the system's degrees of freedom. For instance, amino acid side chains can be simplified into single-point models, and phospholipid head groups can be represented as spherical particles.
Effective Force Field Construction
To accurately model interactions between coarse-grained particles and preserve dynamic behavior fidelity, force fields are developed using statistical potentials, force matching methods, or multi-scale optimization strategies.
Multi-scale Integration
By employing backmapping methods, coarse-grained simulation results can be translated back into atomic-level representations, thereby supporting investigations spanning multiple scales.
