Session Files
|
A session file is a text file that contains a structured list of statements. The statements include instructions for page layout and window content, such as graphic and plot information. A session file is generated whenever you save a work session. Session files can also be created outside of the program using any text editor or generated from other applications.
Session files have the MVW default extension.
Session files can be opened in HyperView, MotionView, HyperGraph, HyperGraph 3D, TextView, and MediaView.
If you are reading files that are on a different drive than where the session file is saved, HyperWorks Desktop saves the full path.
If the session file is saved on the same drive as the files being read, HyperWorks Desktop saves relative path.
If the session file is saved in the same directory as the file, it saves no path.
|
Report Templates
|
Report templates are text files containing structured statements that retain the users reports while they are working. The statements include instructions for page layout and window content, such as graphic and plot information. These files are generated whenever you save a report template.
Report templates have the .tpl default extension.
If you are reading files that are on a different drive than where the report template is saved, HyperWorks Desktop saves the full path.
If the report template is saved on the same drive as the files being read, HyperWorks Desktop saves relative path.
If the report template is saved in the same directory as the file, it saves no path.

Model Files
|
HyperMesh uses its own proprietary format for HyperMesh database files (.hm), which include geometry, meshing, connectors, loads and forces, materials, and everything else that is necessary to pre-process a model prior to sending it to a solver.
In addition, HyperMesh can import and export connectors, finite element models, geometry, and multiple HyperMesh models, and can also export HyperView 3D (H3D) files.
|
Plot Files
|
2-D plot files are any of the data file formats recognized by HyperGraph and any data file format for which a custom import template has been written.
2-D plot files can only be opened in HyperGraph,  , using the file folder button on the Build Plots and Define Curves panels.
Supported 2-D plot files include:
| • | ADAMS REQ and matrix files |
| • | Abaqus mass from DAT files |
| • | Altair HyperForm DAT files |
| • | Altair HyperMesh RES files |

MotionView
MBD Model Files
|
MBD model files are files written using the Model Definition Language (MDL).
Model files can only be opened in MotionView,  , using the  Open Model icon on the Standard Toolbar.
Model files have the MDL extension.
| Note: | See the MDL Reference for more information on Model Definition Language. |

HyperView
Animation Files
|
Animation files are used to view and animate simulation results.
Animation files can only be opened in HyperView,  , using the Load Model panel.
Supported animation files include:
| • | LS-DYNA d3plot and LLNL-DYNA d3plot |
| • | Altair H3D, written by the SIMPACK solver. |
| • | AcuSolve CFD Results (*.log) |
| • | CFD Ensight format (*.encas, *.case) |
|
TextView
Text Files
|
Text files are any files containing only ASCII text.
Text files can only be opened in TextView,  , using the Open File panel.
While text files can have any extension, they must be ASCII text files.
