Abstract: This paper gives an introduction to the program characteristics of the finite element analysis on liquid film lubrication triangular and recta-ngular elemente Samples deal with factors influencing the accuracy of numerical solution are also given for a set ocomparison and analysis.
It is shown that in case thes hypotenuses of triangles pointing to the same direction as the pressure gradient within the region of hat liguid film the best result will be obtained.
Regarding it as a real volume flow, a method of double-triangular-clement was used to calculate the average flow along the boundary, the result showed that the calculating accuracy will be much improved.
