This example problem’s PDEs need to be enforced on all the points in the interior of the geometry to achieve the desired solution. Analogously to the boundaries, this requires first sampling the points inside the required geometry, then specifying the nodes to evaluate on those points, and fin...
Two-dimensional (2D) materials combine many fascinating properties that make them more interesting than their three-dimensional counterparts for a variety of applications. For example, 2D materials exhibit stronger electron-phonon and electron-hole inter
