MSC.Fatigue Export Dialog Box

Durability -> MSC.Fatigue -> Export
Exports Adams results as DAC time history files and/or launches MSC.Fatigue. Currently, only the modal coordinates of flexible bodies are supported. You can combine these modal coordinate time histories in MSC.Fatigue with the modal stresses from MSC Nastran to compute stress time histories, and ultimately, the life or damage of the flexible body.
Learn more about Exporting Data for MSC.Fatigue.
 
For the option:
Do the following:
Flexible Body
Enter the name of the flexible body you want to analyze.
Job Name
Enter the name of the job you want to create. All DAC files will be named with this prefix.
Modal Coordinates
Select if you want to export modal coordinates.
If you select Modal Coordinates, Adams Durability displays the following text boxes:
Analysis
Enter the name of a previously run analysis.
Output Time Start/End
Specify the starting and ending time of the portion of the analysis you want to export. If you do not specify a range, Adams Durability exports the entire analysis.
Run MSC.Fatigue
Select if you want to launch the MSC.Fatigue program.
If you select Run MSC.Fatigue, Adams Durability displays the following text boxes:
Run Command
Enter the command on your system that starts MSC.Fatigue.
Note: Currently, only MSC.Fatigue with MSC Patran is supported; therefore, enter the command that actually runs MSC Patran.
New/Old/XDB (Patran DB)
Select one of the following:
■New - Creates a new MSC Patran database using an MSC Nastran BDF and OP2.
■XDB - Creates a new MSC Patran database using an XDB file.
■Old - Opens an existing MSC Patran database of the finite-element model (FEM) of the flexible body.
Patran DB
Enter the name of the MSC Patran database you want to create or open.
If you select New, Adams Durability displays the following text boxes:
Nastran BDF
Specify the file that contains the MSC Nastran Bulk Data File that was used to generate the Modal Neutral File (MNF) of the flexible body.
Nastran OP2
Specify the MSC Nastran OP2 file that contains the modal stress or strain data for the flexible body. This should be the .out file that was used to generate the MNF of the flexible body or created in the same run as the MNF using the ADMOUT option on the Nastran AdamsMNF command.
If you select XDB, Adams Durability displays the following text boxes:
Nastran XDB
Specify the MSC Nastran XDB file that contains the MSC Nastran model and modal stress or strain data for the flexible body. This should be the .xdb file that was created in the same Nastran run as the MNF with the "PARAM,POST,0" Nastran card. For more information, see Computing MSC Nastran Stress/Strain Modes.
