Research from C. Wenterodt and Colleagues Has Provided New Data on Computational Engineering

摘要

2011 JUL 27 - (VerticalNews.com) -- According to the authors of a study fromrnHamburg, Germany, "When the Helmholtz equation is solved by numerical methods as, e.g., thernfinite element method (FEM), the solution suffers from the so-called pollution effect. Thernpollution is mainly caused by the dispersion, meaning that the numerical wave number disagreesrnwith the wave number of the exact solution."
