Abstract: Based on the modification to the integal domain, an upwind finite element scheme is presented. Just as the first order upwind difference scheme, which is its conterpart in finite difference methods, it applies to construct many numerical schemes on unstructed grids.

Key words: upwind finite element, unstructed grid, modification of integal domain, stencil
