_expl.cntf file
An OptiStruct ASCII format results file.
File Creation
This file is created when the OPTI format is selected in the CONTF I/O Options Entry, in an Explicit Dynamic Analysis (ANALYSIS=NLEXPL).
File Contents
- Result
- Description
- Contact forces
- Contact force results from explicit dynamic analysis (with contact). This file is created when format = OPTI is specified in the CONTF I/O option.
File Format
The _expl.cntf file has the following format.

- Data
- Description
- CONTACT #
- Contact Interface identification number (CTID on the CONTACT Bulk Data Entry).
- FORCE-X
- Component of the total contact force along the X-axis of the Basic system.
- FORCE-Y
- Component of the total contact force along the Y-axis of the Basic system.
- FORCE-Z
- Component of the total contact force along the Z-axis of the Basic system.
- MAGNITUDE
- Magnitude of the total contact force acting on the master surface.
- AREA
- Area of master surface under contact.
- Normal Force
- Resultant force along the normal direction to the master surface.
- Tangent Force
- Resultant force along the tangential direction to the master surface.
Comments
- The output frequency of the results in this file can be controlled by the value of NINT field in the NLOUT entry.
