The .pret file is an OptiStruct ASCII format results file.
Creation of this file is controlled by the PRETBOLT I/O Options Entry.

Description |
Pretension force/adjustment |
Pretension force/adjustment values for pretension bolts in pretensioning and pretensioned subcases. |
The file is sorted by iteration. Output from each iteration starts in the following format:
PRETENSION FORCE/ADJUSTMENT VALUES ON THE PRENTESION SECTIONS |
||||||||||
|
ITERATION |
Iteration_number |
||||||||
Where: ITERATION is a keyword denoting the beginning of a new iteration. Iteration_number is the iteration number. |
||||||||||
|
||||||||||
Each iteration section contains the force/adjustment values for each pretension bolt in each static subcase. Each such subcase section is given the following header: |
||||||||||
|
Subcase |
Subcase_id |
Subcase_label |
|||||||
Where: Subcase is a keyword denoting the beginning of the current subcase section. Subcase_id is the user-defined subcase ID Subcase_label is the user-defined subcase label |
||||||||||
|
||||||||||
Pretension force/adjustment information is then provided, for each bolt, in the following format: |
||||||||||
|
Pretension section ID (PRETENS #) |
Force-incr |
Adjust-incr |
Force-tot |
Adjust-tot |
|
|
|||
Where: Pretension section ID denotes the pretension section ID (SID of the PRETENS bulk data entry). Force-incr is the incremental pretension force value when compared to the previous subcase in the loading sequence. Adjust-incr is the incremental pretension adjustment value when compared to the previous subcase in the loading sequence. Force-tot is the total pretension force value. Adjust-tot is the total pretension adjustment value. |
