In this paper, we propose two numerical methods for a fluid mixture model. The model is usually used to describe the tissue deformations. It contains a nonlinear hyperbolic equation and an elliptic equation. The first numerical method is the generalized difference method based on linear element function space and piecewise constant function space. Numerical experiments show that our scheme is second-order accuracy in space. To eliminate the oscillation near the discontinuities, we design a generalized upwind difference method to solve the fluid model. Numerical results show that the two methods are effective for the considered fluid mixture model.
