Confined seepage underneath hydraulic structures using strong form differential quadrature element method

Abstract EN

Strong Form Differential Quadrature Element Method (DQEM) is a non-ubiquitous technique for solving various physical and engineering problems having arbitrary domain configurations and complicated boundary conditions.

In the present paper, the DQEM is adopted to simulate 2D steady-state confined seepage using quadrilateral elements unprecedentedly.

The method discretizes the studied domain to a number of homogenous isotropic or anisotropic zones/elements.

Techniques for defining boundary conditions are presented.

The numerical modeling process is implemented in a PYTHON computer code.

Various problems are solved in the present paper and the obtained results are compared with the available results of theoretical and numerical methods pre-published in the literature.

Numerical results demonstrate the rigor and eligibility of the unfamiliar approach (DQEM) with less computational efforts.
