Advanced Simulation Library (ASL) – hardware accelerated multiphysics simulation platform

Advanced Simulation Library (ASL) is a free and open source hardware accelerated multiphysics simulation platform (and an extensible general purpose tool for solving Partial Differential Equations).

Its computational engine is written in OpenCL and utilizes matrix-free solution techniques which enable extraordinarily high performance, memory efficiency and deployability on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. The engine is hidden entirely behind simple C++ classes, so that no OpenCL knowledge is required from application programmers.

Mesh-free, immersed boundary approach allows one to move from CAD directly to simulation drastically reducing pre-processing efforts and amount of potential errors. ASL can be used to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, design space exploration, crystallography, etc.

Features include:

  • Numerical methods: Finite Difference, Lattice Boltzmann, Immersed Boundary.
  • Computational engine: implemented in OpenCL, wrapped into C++ classes.
  • Architectures: Embedded systems (FPGA, DSP), CPU, GPU, APU, MIC, clusters/supercomputers.
  • Interfacing: VTK/ParaView, MATLAB (export).
    • import file formats: .stl .vtp .vtk .vti .mnc .dcm.
    • export file formats: .vti .mat.
  • Geometry:
    • flexible and complex geometry using simple rectangular grid.
    • mesh-free, immersed boundary approach allows to move from CAD directly to simulation.
    • generation and manipulation of geometric primitives.
  • Implemented phenomena:
    • Transport processes:
      • multicomponent transport processes.
      • compressible and incompressible fluid flow.
    • Chemical reactions
      • electrode reactions.
    • Elasticity:
      • homogeneous isotropic elasticity.
      • homogeneous isotropic poroelasticity.
    • Interface tracking:
      • evolution of an interface.
      • evolution of an interface with crystallographic kinetics.
  • Cross-platform support – runs under Linux, Mac OS X, and Windows.
