Passive transport in fractured porous media
horizontal and "HHO-shaped" fractures that act as barriers (left and
center) and vertical fractures that act as conduits (right).
We compare three evolutions of the same
initial condition, obtained on different Cartesian meshes (128x128,
64x64, 32x32) and different polynomial degrees (0,1,2). The initial
condition is a random value between +/- 1 inside each element of the
32x32 Cartesian mesh.
We compare four evolutions of the same initial condition, obtained
with different Peclet number. The initial condition is a random
value between +/- 1 on each cells that are inside a circular domain
of the Voronoi mesh and -1 outside.
We perturb the steady solution in order to show the robustness of
the method to capture the interface dynamics subject to a strong
circular velocity fields.
