how make the crack tip more smooth

hello, everyone!
I am an new user of the code-aster and recently I simulate the crack propagation which start from the welding toe of out-of-gusset .
The mesh size of weld toe is 0.1 mm, damax=0.1, the crack is ellipse a=0.1 b=0.1. I crack propagate 14 times. and the crack tip is not smooth, I have tried the the value of the damax(0.01
,0.03,0.05) and also changed the crack shape but the crack tip still not smooth, how can I fix this problem! thank you !   
here is the  comm. files.
regards
