Reduction of iterations for the linear equation solutions in DDA
- application for the orientation averaging of irregularly shaped particles -
摘要
We introduce the method to shorten the number of iterations required in the linear equation solutions of DDA. In the linear equation solution in DDA, the solution is iteratively solved. We give the initial guess, which is close to the actual solution infered from parameters close to the selected one. We apply the method for the orientation averaging of scattering properties of non-symmetric particles. The method reduces the number of iterations into less than 10% for non-symmetric particles with moderate shape variations against the direction of incident light when the interval of the grid angles is set as 5 degree. On the other hand, non-symmetric particles with high shape variations against the direction of incident lights shows iteration ratio of less than 25%.
