| Abstract: | The concept of three dimensional double node jointed element in structural analysis is introduced into fluid flow model, thus a new type of seepage element is defined, which is named double node seepage element. This element is analyzed from its physical instinct; while its mathematical expression in matrices is also given. The element presented can be used to simulate the effect of fault on seepage field. |
