  - Using Multibody Dynamics Flexbodies
    MotionView has many pre-processing and post-processing capabilities with regards to flexible bodies, or flexbodies, for multibody dynamics models.
    - Generating Flexbody H3D Files
      MotionView works with a neutral file called H3D to represent the flexible body. This compact file format stores the necessary information for visualizing the flexbody in the pre-processing window and the modes and interface nodes in the post-processing window. It also stores the modal and nodal information.
    - Visualizing H3D Flexbodies
      Once an H3D file is created, it can be visualized in HyperView.
    - Using H3D Flexbodies in MotionView
    - Flexbody Post-processing
      MotionView models solved in MotionSolve or Adams can be animated in HyperView. In addition, the plots for these models can also be viewed in HyperGraph.

      - Using Flexbodies for Fatigue
        Fatigue Prep Overview
        The Fatigue Prep custom wizard generates ADAMS output files from a flexbody transient run, which can then be used in nCODE Fatigue software. Finite element fatigue requires that flexbody mode shapes be an nCODE FES file, and the flexbody modal participation factors be "n" number of DAC files, where each DAC file contains the time history of a single mode's modal participation factor.
        Importing/Exporting DAC Files
        DAC files can be imported to and exported from HyperGraph.
        Preparing nCODE FES and ASC Files from H3D Flexbody Files
        nCODE fatigue software requires that the stress modes be represented in their FES file format. MotionView allows you to convert these modes from an H3D flexbody file to the nCODE FES file.
        Preparing nCODE DAC Files from ADAMS RES Files
        nCODE fatigue software requires that each time history of modal participation factors be represented in the DAC file format, one file per time history. MotionView provides the conversion option from the ADAMS ASCII file to "n" number of DAC files, where "n" is the number of modes within the flexbody. MotionView modifies the base name accordingly so that unique filenames result.
        Convert DAC Files to ABF Files
        DAC files can be converted to ABF files in two ways.

Convert DAC Files to ABF Files

DAC files can be converted to ABF files in two ways.

Use FatiguePrep to convert the file directly into an Altair Binary Format (ABF) file.
From HyperGraph, select Export > Curves from the File menu.
Select DAC from the Format menu.
For one curve, the data is written to the requested file name. For multiple curves, the base name is modified accordingly to guarantee unique file names.
