      Hi, could you take a look at this link from Help for limitations and best practice of using arclength method? What error/warning message did you encounter with the unconverged case? You might want to adjust the max/min arc radius multiplier using that arclen command. Also, is this a symmetric problem? If it is you can try take advantage of modeling only half/quarter of it for faster solve AND easier convergence.n
