Have there been changes made in between V18 and V19.00.00.22 that would drastically slow down the performance on Conspan? Since receiving the update the speed of running the analysis has gone from seconds to hours to run a simple analysis on a non-continuous simply supported 5 span precast beam bridge. Is there a change to the default settings that could speed up the Analysis, it seems to be cycling endlessly between the "Truck Positions..." bar, and being non-responsive.
Suggest you to uninstall the Version V19.00.00.22 and this folder on C:drive.and then install the latest version V19.00.00.50. Then run the analysis.
If this doesn't work then I would suggest you to create the file from scratch in the latest version.
