<\/p>\nI am doing a frequency statistical analysis using the Hydrodynamics Response module from the workbench. 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. <\/p>\n
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. <\/p>\n
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? <\/p>\n
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. <\/p>\n
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. <\/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":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
