Error: The index was outside the bounds of the array at WriteReport.Units.WriteReport.PrintGeneralResultsReport

When making a print preview of a report in Diamonds 2025, you get the error:

Solution

This error occurs in a model that contains independent structures for which a table of the internal forces is requested in the tab page ‘Global results’ in combinations with the option ‘All meshnodes’.

There are two work-around

• Solution1 : make a separate Diamonds file for each structure
• Solution 2: uncheck the table of the internal forces in the tab page “Global results”. Instead, ask a table of the internal forces in the tab page “Detailed results”. That’s by default for all meshnodes.
