Ansys aqwa convolution error

mailoan2306 · January 4, 2023, 08:24

Hello everyone,

I am simulating the mooring line with the fish farm system.
During the simulation of the mooring line in irregular waves with irregular wave response. However, I got the error
"CONVOLUTION ERROR. The convolution has failed to calculate a satisfactory fit to the added mass/damping for the structure. This is usually caused by insufficient frequencies or an inadequate frequency range. PLEASE-ENSURE THAT THESE ARE SUFFICIENT "BEFORE" contacting user support. Frequency range for structure should be at least 0.247 to 5.695 rad/sec"

I tried to simulate the system with a range frequency from 0.2 to 0.6 rad/s. But the error still occurred.

I hope to receive a solution from everyone.
Thank you so much in advance.
