The Lightweight Integrating Multiphysics Environment for coupling codes (LIME) is a small software package for creating multiphysics simulation codes. LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve di fferent parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defi ned approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code.
To achieve its flexible lightweight design objectives, LIME 1.0 requires that some amount of customized software be written each time a new multiphysics application is created. Also, modest high-level revisions or modifications to most stand-alone physics codes may be required to meet interface requirements. Detailed descriptions of these requirements together with example cases are provided in a users guide.
Features
- Is relatively small in size and complexity, and requires only a few openly available libraries (e.g. Trilinos version 10.X or higher) to build.
- Designed to enable both new and legacy applications to be combined with strong coupling (when needed) through non-linear solution methods (e.g. fixed point, JFNK).
- NOT limited to codes codes written in one particular language or that use a particular numerical discretization approach (e.g. Finite Element), or to physical models expressed only as PDEs.
- The ability to participate in fixed-point iterations is the lowest barrier to entry for an application to be coupled in LIME.
- LIME allows MPI based parallelism in physics codes that can support MPI.
- Comes with a published users guide (with many example problems) and a code-coupling theory manual.
- Distributed under a BSD type license agreement.
