Can you confirm that you've addressed the mesh and QTF(?)  errors lower down in the list? I'm also curious what is under the blanked out section of the output just before the Diffraction module aborted.

Someone please help.

I have a problem that is TIME-STEP IS PROBABLY TOO BIG. For this time-step(0.001 secs) the natural periods of the system throughout the analysis MUST BE GREATER THAN 0.01 seconds. i.e. Frequency LESS THAN 628,319 rad/sec.

Hello,

there are few parameters you would need to check to ensure that your solution doesn't diverge.

First, please check that the mass properties (mass and moment of inertia) are properly set.

Then, in both cases (fenders or mooning), check the values of the stiffness you set for these items. If your mooring system is too stiff, the force response becomes too sensitive to the motion of your structure.

I hope this helps,

With kind regards,

Ingrid
