Integrates all shape components of Residue mode shapes from acceleration to velocity output units, of from velocity to displacement units.
Integration is performed by dividing each shape component by its shape frequency.
If the shapes are Residue mode shapes, each shape is divided by its complex pole (frequency & damping).
UMM mode shapes must be re-scaled to Residue mode shapes before using this command.
Differentiates all shape components of Residue mode shapes from displacement to velocity units or from velocity to acceleration units.
Differentiation is performed by multiplying each shape by its shape frequency.
If the shapes are Residue mode shapes, each shape is multiplied by its complex pole (frequency & damping).
UMM mode shapes must be re-scaled to Residue mode shapes before using this command.
Multiplies all (or selected) shapes together.
A Shape Product shows where all shapes have node lines (zero values), and hence where poor reference DOFs are located.
A Shape Product also shows where all shapes have anti-nodes (large magnitudes), and hence where good reference DOFs are located.
A Shape Product can be displayed in animation on a connected Structure model to locate node lines and anti-nodes.
