Mesh generator

_duplicate_mesh(mesh::AbstractMesh)

Make an exact copy of the input mesh.

basic_mesh()

Generate a toy mesh of two quads and one triangle.

v1 v2 v3 v4 +–-e1–>+–-e5–>+–-e8–>+ ^ | | c3 / e4 c1 e2 c2 e6 e9 | | | / +<–e3–-+<–e7–-+/ v5 v6 v7

circle_mesh(n; r = 1, order = 1)

Mesh a circle (in 2D) with n nodes on the circumference.

line_mesh(n; xmin = 0., xmax = 1., order = 1, names = ("xmin", "xmax"))

Generate a mesh of a line of n vertices.

Example

julia> mesh = line_mesh(5)

ncube_mesh(n::Vector{Int}; order = 1)

Generate either a line mesh, a rectangle mesh, a cubic mesh... depending on the dimension of n.

Argument

• n number of vertices in each spatial directions

Example

mesh_of_a_line = ncube_mesh([10])
mesh_of_a_square = ncube_mesh([4, 5])
mesh_of_a_hexa = ncube_mesh([4, 5, 6])

one_cell_mesh(type::Symbol, order = 1)

Generate a mesh of one cell. type can be :line, :quad, :tri, :hexa, :penta, :pyra.

The argument order refers to the geometry order. It has the same effect as the -order parameter in gmsh.

rectangle_mesh(
    nx,
    ny;
    type = :quad,
    xmin = 0.0,
    xmax = 1.0,
    ymin = 0.0,
    ymax = 1.0,
    order = 1,
    bnd_names = ("xmin", "xmax", "ymin", "ymax"),
)

Generate a 2D mesh of a rectangle with nx and ny vertices in the x and y directions respectively.

Example

julia> mesh = rectangle_mesh(5, 4)

scale(mesh, factor)

Scale the input mesh nodes coordinates by a given factor and return the resulted mesh. The factor can be a number or a vector.

Usefull for debugging.

transform(mesh::AbstractMesh, fun)

Transform the input mesh nodes coordinates by applying the given fun function and return the resulted mesh.

Usefull for debugging.

translate(mesh::AbstractMesh, t::AbstractVector)

Translate the input mesh with vector t.

Usefull for debugging.
