The analysis and calculation of the finite element modeling of a moving boundary between immiscible fluids in a porous medium is presented. One fluid is introduced under prescribed inlet boundary conditions and the motion of the resulting interface boundary studied and calculated. The aforementioned scenario is calculated using a finite element program based on the software, MATLAB. Analytical solutions developed in one dimension illustrate the moving boundary movement and benchmark for numerical solutions. The aim of computer aided calculation is to develop and predict a model applicable to a real situation, yet flexible enough for future adaptation to other problems with little modification.
