beamApplyBC function

beamApplyBC

Boundary constraint for element centroids based on coordinate points. For the x & y direction per centroid create matrix with boundary 1(unfixed) or 0(fixed).

beamApplyBC(beamP, BCtran, BCrot)

Arguments

• beamP: Matrix (2 x n) of beam coordinates.
• BCtran: Boundary constraint for nodes to translate in x or y directions. Input as a non-matrix column.
• BCrot: Boundary constraint for nodes to rotate. Input as a non-matrix column.

Returns

A data frame with constraint parameters applied to each node for directional translation and rotation. Formatted for use in reduced element matrix. - NodeKnownL: Matrix (1 x n) of constraint parameters

Examples

data(beamGeo)

beamBC = beamApplyBC(beamGeo$beamP, beamGeo$BCtran, beamGeo$BCrot)
