Constructor, see JSBeams.EigenValueDynamicSolver for input parameters description

Source:

new EigenValueDynamicSolver object

assemble()

Assembles global stiffness and mass matrix of whole structure from stiffness and mass matrices of particular beams and concMass attribute

Source:

preprocBeams()

Preprocesses all beams (sets their "beam load" and assemble it to global load vecor, set their geometric parameters and stiffness matrices

Source:

solve()

Solves unknown eigenfrequencies and eigenshapes

Source:

update()

Global function for whole simulation process

Source:

updateBeams()

Postprocesses all beams (from computed eigenshapes sets appropriate displacements to them)
