IBAMR - CMake-ified git mirror

What Is IBAMR?

IBAMR is a distributed-memory parallel implementation of the immersed boundary (IB) method with support for Cartesian grid adaptive mesh refinement (AMR). Support for distributed-memory parallelism is via MPI, the Message Passing Interface. Support for spatial adaptivity is via SAMRAI, the Structured Adaptive Mesh Refinement Application Infrastructure, which is developed at the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory.

This implementation of the IB method also makes extensive use of functionality provided by several high-quality third-party software libraries, including:

  • PETSc, the Portable, Extensible Toolkit for Scientific Computation,
  • hypre, a library of high performance preconditioners that features parallel multigrid methods for both structured and unstructured grid problems,
  • HDF5, a general purpose library and file format for storing scientific data,
  • Blitz++, a high-performance C++ array class library, and
  • Silo, a general purpose I/O library and file format for storing scientific data for visualization and post-processing.

IBAMR outputs visualization files that can be read by the VisIt Visualization Tool. Work is also underway to implement support for finite element mechanics models in IBAMR via the libMesh finite element library.

What Is the IB Method?

The immersed boundary (IB) method is a general-purpose numerical method for simulating fluid-structure interaction. The IB formulation of such problems uses an Eulerian description of the fluid and a Lagrangian description of the structure. Interaction equations that take the form of integral equations with delta function kernels couple the Eulerian and Lagrangian variables.

For general information about the IB method, see http://math.nyu.edu/faculty/peskin. For visualizations of simulations that use IBAMR, see http://cims.nyu.edu/~griffith.

Getting Started

  1. [Download CMake] (http://www.cmake.org)

  2. [Clone the repository] (http://git-scm.com/book/en/Git-Basics-Getting-a-Git-Repository#Cloning-an-Existing-Repository)

     $ git clone git://github.com/MSV-Project/IBAMR.git path_to_source/ibamr
    
  3. CMake workflow:

     $ mkdir ibamr-debug # Create out of source directory to build IBAMR
     $ cd ibamr-debug
     $ cmake path_to_source/ibamr # Generate necesary cmake files to build IBAMR
     $ ccmake path_to_source/ibamr # Customize build by modifying variables
    

Source code documentation for IBAMR is available [on-line] (http://ibamr.googlecode.com/svn/doc/ibamr/HEAD/html/annotated.html). Source code documentation is also available for the IBTK support library. File format documentation is also available on-line.
