The following change in Abaqus/CAE 6.14 is a change from previous releases:
Python interprets numbers with leading zeros as octal numbers (for example, 0123 is interpreted as 83.0). Previously, numbers with leading zeros entered in text fields were interpreted as octal numbers. Now, Abaqus/CAE will ignore leading zeros in numbers in text fields before Python interprets them; such numbers are evaluated as decimals. For more information, see “Entering expressions,” Section 3.2.2 of the Abaqus/CAE User's Guide.
