Hi,

I am trying to run some stability analysis within Ansys Hydrodynamic Response on a vessel that I have modelled. However, I am running into the following error:

The model is made up of three interacting structures and I am also using some non-linear catenary mooring lines that are connected between connection points on the structures and fixed points on the seabed. The error does not occur when I run stability analysis on the main vessel, however, when I add the other two structures and the mooring lines to the model, I receive this error message and also the whole structure moves significantly.

Any ideas as to what could be causing this error message will be greatly appreciated.

Thank you.

You could set Maximum Error in Equilibrium to be Manual Definition, and adjust the Maximum Positional Error

Hi,

Thank you for your reply.

I have tried this and I am still getting the error.

I have also manually defined the movement limitations per iteration and the error is still occuring.

Can you please show your model?
