A Multi-Platform High-performance Immersed-Boundary Incompressible Open soUrce Solver

  • AMPHIBIOUS is a finite-differences DNS solver for the incompressible Navier-Stokes equations, based on the immersed-boundary (IB) method

  • AMPHIBIOUS adapts to different environments. It runs on CPUs or GPUs. It computes flows in simple geometries described analytically, or in complex geometries described via STL files

  • AMPHIBIOUS is open-source software, written in CPL, and released under the GPL v3 license

  • AMPHIBIOUS is fast!

AMPHIBIOUS v1.2 is out

Main changes:

  • redesigned handling of STL, without reliance on external libraries
  • ability to assign boundary conditions with wall-normal derivatives
  • introduced optional temperature (passive scalar) equation
  • fixes and extensions
  • initial attempt at cleaning up, compacting and commenting the source
