GlobalMat.2d {FEA}

GlobalMat.2d

Description

Generates global stiffness matrix - once established, the expanded element matrix must be combined to create the global structural stiffness matrix by adding the expanded matrices.

Usage

GlobalMat.2d(meshP, meshT, ExEM)

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.

ExEM

Expanded element matrix

Value

Produces large (n x n) global matrix

GlobalMat

Global matrix

Examples

data(triMesh)
data(fea_ExEM)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
ExEM = fea_ExEM

gloMat = GlobalMat.2d(meshP, meshT, ExEM)
