- Minor fixes to interface
HExS – v2.0.0.0
Update to S&THex
- Update error log viewer, the software will now issue messages in the error log that
include the following types:
ERROR: This type of messages is used for errors in input or results, the software will stop until errors are fixed by the user
WARNING: This type of message is used for warning when parameters are exceeded, the software will continue buy some results may be invalid
MESSAGE: This type of message is used for general software informative messages
INFO: This type of message is used to provide additional information and guidance during operation
New Features: - Added kern tube counts
- Automate multiple cases by simply setting the changing parameters and allowing the software to iterate through these parameters and generate final results.
- Iterate through kern tube counts using the multiple cases feature
Automated mode for multiple case simulation: instead of manually changing values to add a case, this mode
will do the exact without user intervention. The manual mode is still avialable too.
You can now perform a simulation study by changing any of the parameters under the Study scenarios below:
Study parameters 1:
Tube outer diameter, Tube number of passes, Tube length, Number of tubes, Baffle spacing
Study parameters 2:
Uses kern tube counts to iterated between Shell diameters to obtain the number of tubes for a given number of passes.
User can set the study parameters and the software will automate the calculation steps and add the final result to summary screen
where the changes between each can can be detected.
This case study mode will automate the manual input for trial and error to optimise results.
