kinnala/scikit-fem 4.0.0

on GitHub

Highlights from the changelog:

• Added: Mesh.save/Mesh.load now exports/imports Mesh.subdomains and
  Mesh.boundaries
• Added: asm will now accept a list of bases, assemble the same form using
  all of the bases and sum the result (useful for jump terms and mixed meshes, see Example 41)
• Added: MeshTri1DG, MeshQuad1DG, MeshHex1DG, MeshLine1DG; new mesh
  types for describing meshes with a discontinuous topology, e.g., periodic
  meshes (see Example 42)
• Added: ElementTriSkeletonP0 and ElementTriSkeletonP1 for defining
  Lagrange multipliers on the skeleton mesh (see Example 40)
• Added: TrilinearForm for assembling a sparse 3-tensor, e.g., when dealing
  with unknown material data
• Added: partial support for MeshWedge1 and ElementWedge1, the lowest order
  wedge mesh and element
• Added: ElementTriP3, cubic triangular Lagrange element
• Added: ElementTriP4, quartic triangular Lagrange element
• Added: ElementTri15ParamPlate, 15-parameter nonconforming triangular element for plates
• Added: ElementTriBDM1, the lowest order Brezzi-Douglas-Marini element
• Added: Mesh.draw().show() will now visualize any mesh interactively (requires vedo)
• Added: Adaptive refinement for MeshTet1
• Fixed: MappingIsoparametric is now about 2x faster for large meshes thanks
  to additional caching
