Module PlotMSH contains classes and functions for plotting mode shapes obtained from any of the classes derived from ModalBase of the pyOMA project

Todo

  • Implement scale (for correct drawing of axis arrows)

  • Use current axes settings when starting the animation

  • Remove PyQT dependency -> move the signal definitions somewhere else. Where?

  • Restore functionality needed to create the geometry in another GUI

  • Use the logging module to replace print commands at an appropriate logging level

  • Implement the plotting in pyvista for better and faster 3D graphics https://docs.pyvista.org/examples/99-advanced/warp-by-vector-eigenmodes.html

ModeShapePlot(geometry_data[, stabil_calc, ...])

This class is used for displaying modal values and modeshapes obtained by one of the classes derived from ModalBase as part the of the pyOMA project (Bauhaus-Universität Weimar, Institut für Strukturmechanik).
