Respected Sir My issue is with only generating the semi elliptical crack . I want to generate semi elliptical crack in stress concentrated regions and in mid region but only at certain places i am able to make the crack generated

Please see if the following helps (refer to all the 3 parts):

Thank you for the link but my here the video i had followed but couldnt reach the end results. My main aim is to generate cracks in the welded regions which i am not able to do. That is the regions shown below.
Also i always get a warning
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.
2.The fracture parameters computed during solution may be incorrect. Check the Solver Output on the Solution Information object for possible causes.
How to rectify these too
