IBAMR

An adaptive and distributed-memory parallel implementation of the immersed boundary (IB) method

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.

Core IBAMR functionality relies upon several high-quality open-source libraries, including:

  • SAMRAI, the Structured Adaptive Mesh Refinement Application Infrastructure
  • PETSc, the Portable, Extensible Toolkit for Scientific Computation
  • libMesh, a C++ finite element library
  • hypre, a library of high performance preconditioners that features parallel multigrid methods for both structured and unstructured grid problems.

IBAMR also uses functionality provided by a number of additional third-party libraries, including: Boost; Eigen; HDF5; muParser; and Silo.

IBAMR outputs visualization files that can be read by the VisIt Visualization Tool.

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 couple the Eulerian and Lagrangian variables take the form of integral equations with delta function kernels.

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

IBAMR requires a number of third-party libraries. Sample build instructions are provided for a typical Linux installation.

Documentation

Source code documentation for IBAMR is available on-line. Source code documentation is also available for the IBTK support library. File format documentation is also available on-line. There is also list of frequently asked questions.

Support

Support for IBAMR is available via the IBAMR Users Google Group (ibamr-users@googlegroups.com). Discussion related to the continued development of IBAMR is via the IBAMR Developers Google Group (ibamr-dev@googlegroups.com).
