Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Area of Science:

Computational Chemistry
Molecular Dynamics
Multiscale Modeling

Background:

Traditional molecular simulations often require uniform high resolution, leading to computational inefficiency.
Simulating systems with varying resolution needs presents a significant computational challenge.

Purpose of the Study:

To review the fundamental theoretical principles of the adaptive resolution simulation scheme (AdResS).
To present recent extensions of the AdResS method to new physical regimes.

Main Methods:

The adaptive resolution simulation scheme (AdResS) dynamically adjusts the number of degrees of freedom in different spatial regions.
This on-the-fly adaptation allows for localized high-resolution molecular dynamics simulations.

Main Results:

AdResS enables efficient simulations by focusing computational effort only where high resolution is necessary.
The method has been successfully extended to incorporate continuum solvent models.
Recent developments also integrate AdResS with quantum mechanical calculations.

Conclusions:

The adaptive resolution simulation scheme (AdResS) provides a powerful and flexible framework for multiscale molecular simulations.
Extensions to continuum and quantum regimes significantly broaden the applicability of AdResS to complex chemical and physical systems.
