JACOBI Convergence Issue in ANSYS AQWA

[M. Namaki]

I'm currently working on a simulation in ANSYS AQWA (2023 R2) and have encountered a persistent issues that I’d like to better understand and resolve.

I receive the warning:

"JACOBI: Failed to Converge."

This appears during the simulation, but the documentation does not provide much context. I would appreciate any insight into what causes this issue and how to resolve it. 

I need to add that the simulation involves multiple hydrodynamically interacting structures. the project completes successfully despite the warnings, but I would prefer to clean up these issues for better accuracy because I do not trust the results. 

Any advice or suggestions from experienced users would be greatly appreciated.

Hello,

What type of analysis are you running when this warning occurs? Is this in Hydrodynamic Diffraction, or one of the Hydrodynamic Response calculations?
