I am doing it for zero speed and with forward speed. I am using irregular wave and have set the direction, Hs, Tp and Gamma as design parameters (design points). I have these combinations of sea spectra from 0-360 deg with an increment on 15deg in direction.&nbsp;<\/p>\n<p>I get the results for all the design points for zero speed. But for forward speed case, I get the below error at some of the design points. <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/05-04-2024-1712322278-mceclip0.png\"><\/p>\n<p>I am using the non-linear roll damping using bilge properties (taken from actual vessel). I notice that the solver stops after 30 iterations for the design points which gives this error. How to resolve this issue?&nbsp;<\/p>\n<p>I also want to know if there is any way to increase the number of iterations in the frequency statistics analysis from 30 to some higher number.&nbsp;<\/p>\n<p>P.S: I know there is some command CALFER 0 0 1000 to increase the number of iterations, but not know how to use it or is this the right command. I treid using the CALFER in ANALYSIS.dat file of the design point with the error, but after saving it when I run for same design point in the frequency statistical analysis, the analysis.dat file gets overwritten.&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-360685","topic","type-topic","status-closed","hentry","topic-tag-aqwa","topic-tag-aqwa-errors","topic-tag-hydrodynamic-diffraction","topic-tag-hydrodynamic-response"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["40749","180344","183765"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1445"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["360685"],"_bbp_forum_id":["27792"],"_bbp_engagement":["40749","180344","183765"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["362928"],"_bbp_last_active_id":["362928"],"_bbp_last_active_time":["2024-04-18 11:48:37"]},"test":"constantin-bachunited-engineering"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360685","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360685\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=360685"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
