waves

Waves is a collection of general utilities and finite element tools for solving various PDE. The code is written in C++ interfaced in python through SWIG, and is developed at the University of Liège.

Features

Set of python/C++ modules:

• fwk: general utilities (timers, ...)
• tbox: general finite element utilities (mesh handler, nodes/elements handler, ...)
• tboxVtk: VTK extensions for tbox
• waves: 3D(Hex8) transient wave equation solver (FEM)
• fdtd: 2D Maxwell equations (FD)
• flow: 2D(Tri3) and 3D(Tetra4) steady full potential equation solver (FEM)
• heat: 2D(Tri3) steady nonlinear heat equation solver (multiscale FE²M)
• mirrors: 3D(Hex8 and Tetra4) linear thermomechanical equations (FEM)
• katoptron: 3D(Hex8 and Tetra4) linear thermomechanical equations with contact (FEM)
• params: parametric study with Metafor
• tlnos: basic Trilinos examples
• sph: incompressible fluid equations (SPH)

Additional features:

• gmsh support for mesh and post-processing
• vtk/PyQt support for post processing and basic GUI
• OpenBLAS or Intel MKL support
• Eigen3 support for linear algebra
  • Intel Pardiso support
  • MUMPS support
• TBB support for multithreading
• mpi4py support for parallelization
• Trilinos support (for some modules)
