Find Modal Displacement at Point

Export modal displacements at one or more points to a UNV file.

  1. On the Project Tree, open the Analysis Workbench.
  2. Click (Pick info).
  3. Specify the Coordinate system in the drop-down menu.
  4. Choose the desired datum point set in the drop-down menu.
    The dialog will display the points' label and id in the modeling window. You can select the Hide labels check box to hide the display of points' label and ID in the graphics.
  5. Optional: To include rigid body modes in the UNV file during Free-free modal analysis, enable the Export rigid body modes checkbox. By default, these modes are disabled, resulting in the export of only flexible body modes.
  6. Save info to UNV file.
    1. Click the Save to UNV button.
    2. In the dialog, enter a file name and select a save location.
    3. Click Save.

  1. The .unv file contains 3 blocks:
    • The first block contains coordinate system information and it follows dataset number 18 of universal file format.
    • The second block contain the point id’s and their coordinate information. This block follows dataset number 15 of the universal file format.
    • The last block contains the eigen frequency and the modal displacements associated with each point. It follows dataset number 55 of the universal file format.
  2. The datum point set must contain unique IDs represented with integers, if not, SimSolid's internal IDs would be used to represent the point IDs.
  3. Modal displacements are mass normalized in .unv file.
