Summary for: ExtrudedPrismMesh < PrismMeshBase3D

Class summary

ExtrudedPrismMesh Class for extruded prism meshes.

The class creates an extruded 3D mesh with prismatic elements, from a given 2D mesh.

Properties

.Ne2 - number of elements in original 2D mesh

.Nl - number of extruded node layers, equal to numel(this.zs)

.Np2 - number of nodes in original 2D mesh

.isoparametric (boolean) Is the mesh isoparametric.

false by default, corresponding to linearly-extruded non-rotated prismatic elements.

true otherwise. Must be set manually when required.

.zs - z-coordinates of mesh node layers.

Methods

Class methods are listed below. Inherited methods are not included.

.ExtrudedPrismMesh/Bquiver is a function.

[Bvec, h] = Bquiver(msh3, A, els, varargin)

.extrudedMachineMesh constructor.

Call syntax msh3 = extrudedMachineMesh(msh2) to extrude a MachineMesh and generate a new ExtrudedMachineMesh object msh3. Documentation for ExtrudedPrismMesh/ExtrudedPrismMesh doc ExtrudedPrismMesh

.ExtrudedPrismMesh/elementCenters is a function.

x0 = elementCenters(msh3, elem)

.elements_in_layer Indices to all elements in a given layer.

els = elements_in_layer(this, layer), where

• layer : the number of layer OR “mid” or “top” to plot the ceil(number_of_layers/2)th or number_of_layers:th layer, respectively.

.extrude_elements 3D elements corresponding to given 2D

elements.

elements_3D = extrude_elements(this, elements_2D)

Get all 3D equivalents, in all layers.

elements_3D = extrude_elements(this, elements_2D, layers)

Limit to the given layers only.

.extrude_nodes

els = extrude_nodes(msh3, nodes)

els = extrude_nodes(msh3, nodes, layers)

.ExtrudedPrismMesh/getMappingMatrix is a function.

[F, varargout] = getMappingMatrix(this, elements, varargin)

.revert to old reference implementation by default

.ExtrudedPrismMesh/grad_quiver is a function.

[Bvec, h] = grad_quiver(msh3, A, els, varargin)

.ExtrudedPrismMesh/layer_interpolation_matrix is a function.

P = layer_interpolation_matrix(this, coordinates, element_layer)

.ExtrudedPrismMesh/plot_nodes is a function.

plot_nodes(this, n, varargin)

.ExtrudedPrismMesh/t is a function.

y = t(msh3)

.TRIPLOT Plots a 2D triangulation

TRIPLOT(TRI,X,Y) displays the triangles defined in the M-by-3 matrix TRI. A row of TRI contains indices into X,Y that define a single triangle. The default line color is blue.

TRIPLOT(TR) displays the triangles in the triangulation TR.

TRIPLOT(…,COLOR) uses the string COLOR as the line color.

H = TRIPLOT(…) returns a line handle representing the displayed triangles edges.

TRIPLOT(…,’param’,’value’,’param’,’value’…) allows additional line param/value pairs to be used when creating the plot.

Example 1: X = rand(10,2); dt = delaunayTriangulation(X); triplot(dt)

Example 2: % Plotting a Delaunay triangulation in face-vertex format X = rand(10,2); dt = delaunayTriangulation(X); tri = dt(:,:); triplot(tri, X(:,1), X(:,2));
