What's new in Build 4631?

Released April 3rd 2024

Feature update Database Connections!

• Define and manage Database Connections easily within Simul8, no need to use external tools such as Microsoft's ODBC Data Sources. Use new connections to import and export data.
• Connection information can now be saved within a simulation, meaning shared models can access the same data, even when opened by someone other than the model builder.
• No additional file installation required for supported databases (such as SQL Server, MySQL, PostgreSQL).
• Simul8 Online can now connect to supported databases (as above). Simulations with database connections created in desktop will work identically online and vice-versa.

Finance data in spreadsheets

• Import from/export to spreadsheet buttons added to the financial input summary dialog so that object finance data can be edited from a spreadsheet
• New Visual Logic commands added to import finance from spreadsheet and export finance to spreadsheet so that this can be used without opening the dialog

Plus many more improvements and fixes...

• Gridlines and Headers checkboxes added to spreadsheet view tab
• Fixes spreadsheet buttons so that the caption can be changed
• Fixes routing arrow handles not clearing if an arrow is selected and you then select a different arrow
• Fixes queue prioritization order so that items in a queue that are prioritized by label are also ordered in their priority groups by arrival order
• Fixes date/time cell formatting in spreadsheets
• Fixes select resources by label having resources in the wrong mode

What's new in Build 4580?

Released December 8th 2023

• Routing arrows are stepped by default on new simulations. Existing simulations will open with existing straight arrows so that any layout and look of the model is not altered.
• Clicking on an arrow highlights it so that it can be easily seen.
• The middle section of a stepped arrow can be dragged to a new position using the square handle in the centre to accurately position it.
• "Restore 2024 Default Icons" button added to Preferences > Display to update building block icons in existing simulations to Simul8 2024 new interface icons.
• Fixes Probability Profile bug where value row was disappearing when clicked.
• Fixes an issue in Resource Results by Activity where the work item did not always know what it's intended activity was going to be.
• Fixes random number stream integer overflow bug.
• Fixes ribbon check boxes show outline and fill colour on text boxes.
