visualdynamics.gui.modal_response_panel

modal_response_panel

The Compute Modal Responses pane beside the plot: which response of each mode to keep, what it is computed from, a preview, and the button that computes it.

It opens on a time history with force channels, or a CPSD of forces, selected together with a shape set: the whole set for every mode, or the modes picked in its grid. The plot previews the modal responses over the start of the record, or each mode's response autospectrum for a CPSD; Compute runs the project's compute_modal_responses, which puts them in a new object linked beside the forces (principle 13: select, see, set, apply).

Classes:

Name Description
ModalResponsePanel

Classes

ModalResponsePanel 

ModalResponsePanel(parent: QWidget | None = None)

Bases: QWidget

The response to keep, emitted as its name ('acceleration') when it changes and when Compute is pressed.

Methods:

Name Description
quantity

The response chosen.
show_settings

Put the quantity up without emitting it.
show_reading

The rows under the setting, and the note under them; lines
