Study on Key Issues of the One-step Inverse Method

摘要

Even though the inverse method is less accurate than that of the incremental one , it has great potential in the conceptual design stage for its less calculation load and quick speed. However, it faces a number of unsolved problems , which limit its application . The first question is how to find a suitable initial solution while the other one is how to deal with the numerical problems caused by the vertical walls. In this paper, new methods have been proposed to solve above two questions. The methods have also been coded and applied to two parts to test its feasibility.
