Meshes in 3D

load_mesh_file(file)

Loads 3D mesh files.

read_comsol_mesh(mesh_file)

Loads the coordinates, topology and entites from a ".mphtxt" file.

load3dTriangularMesh(mesh_file;m=3,n=3,geometry_order=:linear,physics_order=:geometry,
                                beta_type=:legendre,entites=false,removed_entites=[-1])

Returns a Mesh3d from the geoemtry described in mesh_file.

Supports .obj, .ply, .stl, .off, .2DM files using MeshIO.jl and FileIO.jl.

load3dTriangularComsolMesh(mesh_file;m=3,n=3, geometry_order=:quadratic,
    physics_order=:geometry,beta_type=:legendre,entites=false,removed_entites=[-1])

load3dQuadComsolMesh(mesh_file;m=4,n=4,geometry_order=:quadratic,
        physics_order=:geometry,beta_type=:legendre,entites=false,removed_entites=[-1])

Mesh3d

Contains relevant information for

remove_unused_nodes(topology)

Reindexing topology so that the indexing has no gaps.

normalize_vector!(normals)

Normalizes the columns of normals.

tangents!(normals, tangent1, tangent2)

Inplace computation of two tagents of the columns of normals. Results are saved in tangent1 and tangent2 respectively.

get_element_normals(shape_function::Triangular,coordinates, topology)

Compute the normal as the average normal of all normals from the different elements that a coordinate is connected to via topology.

compute_sources(shape_function,physics_function,topology,coordinates)

Computes the nodal position for discontinuous elements.

set_physics_element(physics_order,shape_function,beta_type)

Returns element of type physics_order with the same interpolation as shape_function. For discontinuous elements beta_type defines the position of the internal nodes.

cross!(normal::AbstractVector,a::AbstractVector,b::AbstractVector)

Inplace computation of the cross product a × b. Result saved in normal.

cross_product!(normals,tangent,sangent)

Inplace computation of the cross product between every column of tangent and sangent. Results are saved in the corresponding column of normals.

column_norms!(jacobian,normals)

Computing norms of columns in normals. Saved in jacobian. Everything assumed to be 3d.

normalize!(normals,jacobian)

Dividing each column of normals with jacobian.

jacobian!(basisElement::SurfaceFunction,coordinates,normals,tangent,sangent,jacobian)

Inplace computations of the jacobian of the basisElement::SurfaceFunctionat the coordinates. The results are saved intangent,sangent,normalsandjacobian`.
