The MultiBench test suite is a unified implementation of fourteen leading multiscale methods for static loading conditions studied
In 2009, Miller and Tadmor published a paper providing a unified framework and performance benchmark for fourteen leading multiscale methods including QC [136]. The code used in the performace benchmark testing, called "MultiBench", is available here. The methods supported by MultiBench are:
| Method | Acronym | Key References |
|---|---|---|
| Quasicontinuum | QC | [16, 12] |
| Coupling of Length Scales | CLS | [11] |
| Bridging Domain | BD | [18] |
| Bridging Scale Method | BSM | [17, 10] |
| Composite Grid Atomistic Continuum Method | CACM | [3] |
| Cluster-Energy Quasicontinuum | CQC-E | [4] |
| Ghost-Force Corrected Quasicontinuum | QC-GFC | [13] |
| Ghost-Force Corrected Cluster-Energy Quasicontinuum | CQC-GFC | [4] |
| Finite-Element/Atomistics Method | FEAt | [7] |
| Coupled Atomistics and Discrete Dislocations | CADD | [14, 15] |
| Hybrid Simulation Method | HSM | [8] |
| Concurrent Atomistic to Continuum Coupling | AtC | [5, 1, 2, 9] |
| Ghost-Force Corrected Concurrent Atomistic to Continuum Coupling | AtC-GFC | unpublished |
| Cluster-Force Quasicontinuum | CQC-F | [6] |
A description of the unified framework encompassing all fourteen methods and the results of a benchmark comparing them are available in these publications:
