I am doing the same estudy and when the results it is solved I receive a error mensager "A fracture result is specified by time instead of by set. If the time lies between two result sets, no interpolation is performed. Instead, there are two possibilities: (1) if there are no mesh changes, the lower set applies; (2) if there are mesh changes, the closest set applies"

I receive the value 1157,2Mpa.mm^(0,5), but in my calculation should be close to 1608,92 according Abaqus or 1726,55 according API standard.

someone could help me?

semi eliptical external crack dimension (longitudinal direction):
63,2mm major radius
15,8mm minor radius
pipe external radius: 1158,8mm
pipe internal radius: 1139,8mm
pipe lenght: 800mm
Internal pressure: 3.5Mpa
