On opening an existing file, a error message appears with the phrase “Open File Failed: Broken Data Set: Trying to find ‘AssignmentDelayWeighting’ on parent item ‘Modelling’.”
This is caused by an incompatibility between files generated by TRANSYT versions 15.0.0, 15.0.1 and 15.0.2, and future versions.
Solution: Update your copy of TRANSYT 15 to the latest version. To do this, simply obtain a download code from software@trl.co.uk, and then go to www.trlsoftware.co.uk/downloads to enter the code.
