learnFEM

some julia codes for learning fem

• ch1, ch2, and ch3 codes are based on M.G. Larson & F. Bengzon, The Finite Element Method: Theory, Implementation, and Applications.
• gmsh contains some .geo files and some julia scripts to use Gmsh.
• pbc contains .jl files which implement Dirichlet Periodic boundary condition. pbc1.jl use Ferrite to generate the grid. pbc2.jl uses Gmsh to generate the grid.
• Be careful! In pml/periodic_surface.jl we need to deal the BCValues() in ConstraintHandler().
