Dear sir, I’m new student who is learn about flotation and upending analysis using SACS from Bentley. In my analysis, I got too much error when using this software. The bottom of jacket always touches the mudline when the hook elevate upward. When I decrease the length of string, the jacket will rotate upward and pitch angle will be -100 degree. When I increase the depth of the sea level, the problem is still happen.
And one more thing,this error is always appear in error log
*** error-test is not recognizable
*** error exceeded max iterations for total increment number 1
*** error exceeded max iterations for total increment number 2
*** error exceeded max iterations for total increment number 3
*** error exceeded max iterations for total increment number 4
I hope forum can help me to refine this problem. Thank you.
