Problem:

Does AutoPIPE as a whole have the same type of converging issues as seen by other programs?

Solution:

AutoPIPE has a more advanced non-linear analysis than other products, developed in the early 80's out of University of California, Berkley. Very rarely does it not converge. Typically when Users enter incorrect soil properties or very closely spaced supports e.g. 1-2' spacing may cause some oscillation of the solution. The program will not hang but the user can chose to stop the analysis and view the results at that iterative state. We have heard complaints from many Caesar Users about Caesar's converging issues. In fact one major German Company using Caesar sent us this quote.

"If friction coefficients are defined for supports in CAESAR II, there is a risk, if no convergence is reached the program is hanging. In order to fix this, the user should suppress the friction coefficients on 1 or more supports. This problem is NOT present in AutoPIPE."

However it does occur, we encourage our users to contact our technical support in order to help solve such issues.
