beamReducedEM {FEA}

beamReducedEM

Description

Reduced stiffness matrix - use boundary condition to reduce matrix to smaller form by removing systems that are bound.

Usage

beamReducedEM(GMat, NodeKnownL)

Arguments

GMat

Global stiffness matrix

NodeKnownL

data frame with constraint parameters applied to each node in the x and y directions. Formatted for use in reduced element matrix. Generated from ApplyBC function.

Value

Produces a large matrix.

ReducedEM

Reduced element matrix.

Examples

data(beamBC)
data(beamGloMat)

NodeKnownL = beamBC
GMat = beamGloMat
beamREM = beamReducedEM(GMat, NodeKnownL)
