Meshes

Meshes in FiniteElementContainers leverage a very abstract interface. Currently, only an Exodus interface is directly supported within the main package but others could be readily supported through package extensions which we are planning on.

FiniteElementContainers.FileMesh — Type
struct FileMesh{MeshObj, MeshType} <: FiniteElementContainers.AbstractMesh

  • file_name::String

  • mesh_obj::Any

Mesh type that has a handle to an open mesh file object. This type's methods are "overridden" in extensions.

See FiniteElementContainersExodusExt for an example.

Structured Meshes

Simple structured meshes on rectangles or parallepipeds can be create through StructuredMesh mesh type.

FiniteElementContainers.StructuredMesh — Type
struct StructuredMesh{ND, RT<:Number, IT<:Integer} <: FiniteElementContainers.AbstractMesh

  • nodal_coords::H1Field{RT, Vector{RT}, ND} where {ND, RT<:Number}

  • element_block_names::Dict{Int64, Symbol}

  • element_types::Dict{Symbol, Symbol}

  • element_conns::Dict{Symbol, Matrix{IT}} where IT<:Integer

  • element_id_map::Vector{IT} where IT<:Integer

  • element_id_maps::Dict{Symbol, Vector{IT}} where IT<:Integer

  • node_id_map::Vector{IT} where IT<:Integer

  • nodeset_names::Dict{IT, Symbol} where IT<:Integer

  • nodeset_nodes::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_names::Dict{IT, Symbol} where IT<:Integer

  • sideset_elems::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_nodes::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_sides::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_side_nodes::Dict{Symbol, Matrix{IT}} where IT<:Integer

Unstructured Meshes

Unstructured meshes (e.g. those read from a file created by a mesher) can be created with the following mesh type

FiniteElementContainers.UnstructuredMesh — Type
struct UnstructuredMesh{MeshObj, ND, RT<:Number, IT<:Integer, EdgeConns, FaceConns} <: FiniteElementContainers.AbstractMesh

  • mesh_obj::Any

  • nodal_coords::H1Field{RT, Vector{RT}, ND} where {ND, RT<:Number}

  • element_block_names::Dict{IT, Symbol} where IT<:Integer

  • element_types::Dict{Symbol, Symbol}

  • element_conns::Dict{Symbol, Matrix{IT}} where IT<:Integer

  • element_id_map::Vector{IT} where IT<:Integer

  • element_id_maps::Dict{Symbol, Vector{IT}} where IT<:Integer

  • node_id_map::Vector{IT} where IT<:Integer

  • nodeset_names::Dict{IT, Symbol} where IT<:Integer

  • nodeset_nodes::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_names::Dict{Int64, Symbol}

  • sideset_elems::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_nodes::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_sides::Dict{Symbol, Vector{IT}} where IT<:Integer

  • sideset_side_nodes::Dict{Symbol, Matrix{IT}} where IT<:Integer

  • edge_conns::Any

  • face_conns::Any

FiniteElementContainers.UnstructuredMesh — Method
UnstructuredMesh(
    file_type::FiniteElementContainers.AbstractMeshFileType,
    file_name::String;
    kwargs...
) -> UnstructuredMesh{MeshObj, ND, RT, Int64, EdgeConns, Nothing} where {MeshObj, ND, RT<:Number, EdgeConns}
source
FiniteElementContainers.UnstructuredMesh — Method
UnstructuredMesh(
    file::FileMesh{T};
    create_edges,
    create_faces,
    interp_type,
    p_order,
    space_type
) -> UnstructuredMesh{MeshObj, ND, RT, Int64, EdgeConns, Nothing} where {MeshObj, ND, RT<:Number, EdgeConns}

TODO change the interface so we don't need createedges/createfaces. We should parse the interpolation/space type and determine this change in behavior from these inputs...
