Results in CTF File for Other Analysis Types
Results in CTF file for other analysis types
More recent versions of Ansys ls-dyna, typically LS971R5 onwards, can also use the Contact Force File (also known as Interface Force File) to contain analysis-specific data at segments. This feature is not well documented, so documentation is sketchy, however the following analysis types may produce the following components:
| Analysis type | Component names | Meaning |
|
CPM
(airbag particle method)
DEM (unknown) ALE |
IPR_PRESSURE
IFX_X_FORCE IFY_Y_FORCE IFZ_Z_FORCE IFM_FORCE_MAG |
Contact pressure Contact forces in the global system |
| ALE only | Slipping speed data |
Because this file seems to be growing in both content and usage, and the documentation can lag behind this, D3PLOT also provides access to all of its data components as "raw" scalar data of unknown type. The data component names are generic:
| Component names | Meaning |
|
1st data component
nth data component |
The value of n above is determined by the file contents, but values of 4, 8, 16, 17, 21, and 23 are typical.
If you use these "raw" data components the interpretation of the data is your responsibility! Oasys Ltd Support may be able to advise about their content - please ask.
