The purpose of this benchmark is to test the source term type of NodalSourceTerm being applied to the hydraulic equation in the computations with the Taylor-Hood elements, e.g., the pressure interpolation using linear shape function, and the displacement interpolation using quadratic shape function.

The problem is solved on a rectangular domain 2 m $\times$ 1 m. Nodal fluid flux is applied on the left boundary nodes with a value of 0.001 kg/s via the property of NodalSourceTerm. The pore pressure on the right boundary is equal to the initial pore pressure of $10^5$ Pa. The displacement in the normal direction of all boundaries except the left one is fixed.

Fluid and solid are incompressible.

All involved parameters are listed in the following tables:

Property | Value | Unit |
---|---|---|

Fluid density | $10^3$ | kg/m$^3$ |

Viscosity | $10^{-3}$ | Pa$\cdot$s |

Permeability | $10^{-14}$ | m$^2$ |

Young’s modulus (bulk) | $2.5\cdot 10^9$ | Pa |

Poisson ratio (bulk) | $0.27$ | - |

Biot coefficient | $0.9$ | - |

The time period of 86400 is discretised into 100 steps.

The distributions of pressure and displacement at the end time are shown in the following figure:
