PetIBM - toolbox and applications of the immersed-boundary method on distributed-memory architectures (v0.5.3)

PetIBM is a C++ library with ready-to-use application codes to solve the two- and three-dimensional incompressible Navier-Stokes equations on fixed structured Cartesian grids via a projection method. PetIBM implements several immersed boundary methods (IBM) and can be used to compute the flow around multiple moving rigid immersed boundaries (with prescribed kinematics).

PetIBM relies on data structures and parallel routines of PETSc (Portable, Extensible Toolkit for Scientific Computation) to run on memory-distributed architectures. PetIBM can also solve linear systems on multiple distributed CUDA-capable GPU devices with the NVIDIA AmgX library and AmgXWrapper. The software package includes extended documentation as well as many examples to guide users.
