Mode Shape Tool

Follow

The Mode Shape Tool allows users to easily visualize the mode shape data stored from an OnScale run. When the extensive mode shape datasets are stored in an OnScale run, a SHPHST (time histories) file containing all the velocity information is created. In addition to this, if the user requests data overlays from the mode shape information, a FLXSHP (data arrays) file will also be stored.

The Mode Shape Tool can be called from the Tools tab in Post Processor:

To load the SHPHST file generated by the OnScale run, the user must use the Open button in the Load Results section. Once loaded the user will be presented with a graphical representation of their model and all the possible specifications needed to plot different mode shapes.

To operate the tool, the user must define the frequency of interest and nodal range they wish to capture. After setting the frequency of interest, simply click start. The user can create movies of the mode shape across the 360 degree phase angle range or can capture the mode shape displacement at specified phase angles.

Mode Shape Images

Mode shape images can be saved using the Save Active View icon down at the right hand corner of the Mode Shape Tool window. All images can be saved as:

  • PNG
  • BMP
  • JPEG
  • GIF

Mode Shape Movies

All mode shape movies are automatically saved in MPG format once the user selects Start. These movies are given the default name modeshape-filename where filename is the name of the file used to obtain the mode shape datasets.
