Examples ======== 2D/3D compression test ---------------------- We consider the rectangular domain 10x10m and following boundary conditions: *ux=0* at left and right edges, *uy=0* at the bottom edge; left, right and bottom edges are assumed to be impermeable. The permeable upper boundary is loaded by boundary traction *h(t)* and *p=0*. .. image:: geom_bc_t2_2.png :width: 60 % The pore pressure and seepage velocity at times *t=0.03s* and *t=0.13s* are presented in the following figures. .. image:: porodynhe_example2d_simple_fig1.png :width: 40 % .. image:: porodynhe_example2d_simple_fig2.png :width: 40 % The input file for 2D example is `porodynhe_example2d_simple.py `_. The input file for the similar simulation in 3D is `porodynhe_example3d_simple.py `_. 2D partial compression test --------------------------- In this example, we consider the square-shaped domain 10x10m. The boundary conditions are shown in the figure bellow and are as follows: *ux = 0* at left and right edges, *uy=0* at the bottom edge; left, right and bottom edges are assumed to be impermeable. The upper boundary is loaded by boundary traction *h(t)* on its right half which is also non-permeable. The fluid can evacuate through its left upper part, where *p=0* is prescribed. .. image:: geom_bc_t2_3.png :width: 60 % The pore pressure and seepage velocity at times *t=0.03s* and *t=0.13s* are presented in the following figures. .. image:: porodynhe_example2d_fig1.png :width: 80 % .. image:: porodynhe_example2d_fig2.png :width: 80 % The time responses of the linear and non-linear models under partial compression at two mesh nodes L and R are compared here: .. image:: porodynhe_lin_x_nonlin_t2_v2.png :width: 70 % The example definition file: `porodynhe_example2d.py `_. 3D torsion test --------------- The cylinder sample is fully fixed at the bottom surface and twisted at the top surface. The fluid can evacuate only through the bottom part, all other sides are non-permeable. The pore pressure and seepage velocity at a given time are dispalyed in the figure below. .. image:: porodynhe_example3d_fig1.png :width: 80 % The example definition file: `porodynhe_example3d.py `_.
