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.AbstractMesh — Type

abstract type AbstractMesh

source

FiniteElementContainers.FileMesh — Type

struct FileMesh{MeshObj} <: 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.

FiniteElementContainers.file_name — Method

file_name(mesh::FiniteElementContainers.AbstractMesh) -> Any

Returns file name for an mesh type

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, EConns} <: FiniteElementContainers.AbstractMesh

nodal_coords::H1Field{RT, Vector{RT}, ND} where {ND, RT<:Number}
element_block_names::Vector{Symbol}
element_types::Vector{Symbol}
element_conns::Any
element_id_maps::Dict{Symbol, Vector{IT}} where IT<:Integer
node_id_map::Vector{IT} where IT<:Integer
nodeset_nodes::Dict{Symbol, Vector{IT}} 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

source

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, EConns, EdgeConns, FaceConns} <: FiniteElementContainers.AbstractMesh

mesh_obj::Any
nodal_coords::H1Field{RT, Vector{RT}, ND} where {ND, RT<:Number}
element_block_names::Vector{Symbol}
element_types::Vector{Symbol}
element_conns::Any
element_id_maps::Dict{Symbol, Vector{IT}} where IT<:Integer
node_id_map::Vector{IT} where IT<:Integer
nodeset_nodes::Dict{Symbol, Vector{IT}} 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
edge_conns::Any
face_conns::Any
