AutoAdjust.2d: AutoAdjust.2d

In FEA: Finite Element Modeling for R

AutoAdjust.2d

Description

Allows for automatic refinement of the triangular mesh generated based on given parameters. Will remove elements that are outside the margin of the geometry.

Usage

AutoAdjust.2d(meshP, meshT, edge, centroid, AspectR, AR)

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.
edge	Coordinate points of the initial geometry.
centroid	Matrix (2 x n) of triangle elements.
AspectR	Aspect ratio of each triangle element.
AR	maximum desired aspect ratio, numeric value.

Value

Generates new mesh and centroid tables

Meshpts	Includes both new mesh coordinate points and triangulation of points.
Centroids	Centroid positions for each triangle element.

Examples

data(triMesh)
data(polyshape)
data(dime)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
edge =  polyshape$Line
centroid = triMesh$Centroids
AspectR = dime$AspectRatio
AR = 10

auto = AutoAdjust.2d(meshP, meshT, edge, centroid, AspectR, AR)
