Following the release of Oasys Suite 17.0 in April 2020, we became aware of an issue that can occasionally be observed when reading keyword files. We have since identified a cause and a fix has been implemented in Oasys Suite 17.1 (more information here).
When might you encounter the problem?
The issue can occur when reading elements in a keyword file where the referenced nodes are yet to be defined (for example, if nodes are in a different include file to the elements that refer to them). It can also occur when reading data within a *INCLUDE_TRANSFORM. The symptoms of the issue should be obvious, and you will see one of the following:
a) Model referring to nodes that do not exist (will be visibly noticeable as per image below as well as identified through a model check):
b) Failure to read a model (or a crash) along with the following accompanying error messages in the dialogue feedback area:
What have we done to fix the problem?
We have identified the cause and a fix will be implemented in version 17.1, which should be released later this year.
What can you do as a workaround in the meantime?
The workaround is straightforward and fixes the problem. By adding a preference to your oa_pref file, you can turn off the addition to v17.0 that contains the issue. The addition was related to speeding up the reading of solid element information – turning the option off reverts this logic to the same used in v16.1. This can be done in several ways:
1. Turning the option off interactively in Oasys PRIMER
Go to Model->Utilities->Details
In the panel that opens, turn OFF the “Element node label lookup” option then “Save all settings to oa_pref file”:
Saving the settings to the oa_pref file means you do not need to change this setting every time you run Oasys PRIMER.
2. Turning the option off by adding the preference manually to your oa_pref file
Add the following line to your oa_pref file:
primer*threading_status: 0xfffeffff
Note you can add this to your home oa_pref file or shared oa_pref files that exist in your OA_INSTALL or OA_ADMIN area.
3. Preferences editor
Instead of manually editing your oa_pref file, you can add the preference via PRIMER, D3PLOT or T/HIS by selecting Options → Edit preferences (or clicking Preferences in Oasys SHELL). Browse to PRIMER → tuning → threading_status in the preferences tree, tick Active, enter the appropriate text as shown below, and then File → Save.
