Dimensions.2d: Dimensions.2d

In FEA: Finite Element Modeling for R

Dimensions.2d

Description

Calculates dimensional values for each triangular element, including truss length & angles, distance from nodal point to centroid, aspect ratio of each triangle element, and area of the triangle.

Usage

Dimensions.2d(meshP, meshT, centroid)

Arguments

meshP	Matrix (2 x n) containing coordinate points of the mesh nodes.
meshT	Matrix (3 x n) containing the number of the coordinate point that forms a given triangle within the mesh.
centroid	Matrix (2 x n) containing coordinate points of the centroid of each triangular element.

Value

Evaluation of triangle elements truss, angle, and area.

Truss	Nodal pairs that form each truss.
TrussLength	Distance between each paired nodes forming a truss, its length.
Dist2Cent	Shortest distance from truss to triangle centroid.
Truss angle	Angles of the triangle created from truss meeting.
AspectRatio	Aspect ratio of triangle elements.
Area	Area within triangle elements.

Examples

data(triMesh)
data(polyshape)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
centroid = triMesh$Centroids

dime = Dimensions.2d(meshP, meshT, centroid)
