[Solved] Acu-T 5403 DCFSI - Error

hello experts,

I have faced an error when doing AcuSolve tutorial Acu-T-5403 DCFSI.
I have completely followed the tutorial step by step.

The AcuSolve and OptiStruct solver started and coupled together.

However, after a few time steps, the acuTail displayed below error:

Did anyone face this issue before?

What is the reason and is there any solution for this?

 

Thanks in advance!

    I found the issue.  For the AcuSolve Solution Strategy parameters, if you go through the instructions, Max Stagger Iterations is set to 20.  However, if you only view the image, the setting is 5 for the same parameter.  With max stagger iterations = 5, I get the same error.  If instead we go with the instructions and set it to 20, it proceeds as expected.

    hi AcuPro,

    Thank you very much for your help.
    It's true that i followed the image in the tutorial :D
    Unbelievable that the instructions and the image are different.
    I don't know that the writer do the double check before publish the document or not :D
