Input and Output File Formats

The MotionSolve input format, MotionSolve XML, is based on the XML standard. All model information is contained within the MotionSolve XML input file with one exception: the flexbody information is contained in an H3D file. The self-contained nature of MotionSolve XML is intended to ease the model sharing and free you from having to collect all the files referenced in your models.

MotionSolve always produces the following output files:
  • LOG file: Contains messages from the solver, such as solution progress, errors and warnings, and CPU time.
  • MRF file: Contains the solver results. It can be used for creating 2D and 3D plots using HyperGraph and HyperGraph 3D. However, its main purpose is to facilitate the creation of the three files described below.
The following are optional:
  • ABF file: Intended for creating 2D and 3D plots using HyperGraph and HyperGraph 3D.
  • H3D file: Used for animating the results using HyperView.
  • PLT file: Contains your plot data in ASCII format. It is used for transferring loads to Nastran and OptiStruct using the Load Export utility in MotionView, but it can also be used to create 2D and 3D plots using HyperGraph 2D and HyperGraph 3D.
