Elastic wave simulations using SEM

• \src

  • FEM/SEM solvers
  • sem1d.ipynb wave equation solver (1D)
  • fem2D.py main module, used by all 2D FEM and SEM notebooks
  • fem2d.ipynb Poisson equation solver, using P1 elements (linear)
  • fem2dDyn.ipynb Accoustic wave equation solver using P1 elements (not working)
  • fem2dElast.ipynb Elastic static equation solver using P1 elements (not working)
  • sem2d.ipynb Poisson equation solver (SEM)
  • sem2dDyn.ipynb Accoustic wave equation solver (SEM)
  • sem2dElast.ipynb Static elastic equation solver (SEM)
  • sem2dDynElast.ipynb Elastic Wave Equation solver (SEM), weird results : anisotropic wave propagation
  • MESH BUILDERS
  • build_gmsh.py Build 2D building meshes (poor quality mesh, working)
  • buildingMesh.py Build 2D building meshes (high quality mesh, not working : nodes dupplicated)
  • simpleMeshes.py functions to build rectangle meshes

• \meshes gmsh mesh files .msh and geometry files (for building meshes) .geo

• \quadratureRules data of GL and GLL quadrature rules

• \references documentation on FEM,SEM an elastic laws

TODO

• corriger élastique dynamique en SEM
• implémenter calcul de la déformation $\varepsilon$ et de la contrainte $\sigma$
