Abstract
Elements which utilize higher than linear basis function variations of the unknown potential are well known and have been extensively studied over the last three decades. This is an instance where the use of finite elements in charged particle optics lags quite far behind its use in other subjects such as civil and mechanical engineering. Detailed studies have shown that in general, higher-order elements are more accurate than first-order elements, but that this advantage depends on the precise problem under investigation [1].
