The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid compressibility is analyzed by the use of COMSOL Multiphysics® software. The impact of water pressure on the upstream face of the dam is obtained by the computation of stress and displacements for the arch dam considering compression of fluid element. The fluid flow in the dam is described by the in compressible Navier-Stokes equations for 2D Dam model and the Solid Mechanics interface features for stress analysis and for solving the displacements.
