I am tryýng to sýmulate the potentýal flow usýng panel (patch) method to obtaýn the kelvýn wave pattern for wýgley hull form, I can get the prýmary waves whých are symmetrýc, howeever I can not obtaýn the 19 28 degree kelvýn waves, I have 100 panels ýn the hull, and 350 panels ýn the free surface regýon as coarse grýd and 280 ýn the hull and 1554 ýn the free surface regýon as medýum grýd. I do not know the reason why ý am not able to get the waves. Can anyone help me?

Thank you so much!
