Detailed Description
Class representing the perforated plate benchmark.
See the example Fig. 38 in the recent immersed boundary paper coming out of Tom's group).
The following global information is needed: (a) The center of the hole; (b) the radius of the hole denoted by variable R. The function Alpha receives the global coordinates X and Y of the point under consideration. (may be a vertex of an integration element during the set up of the adaptive integration structure, or an intergration point during the integration of the stiffness matrix).

◆ Alpha()
|
virtual |
Performs the inside-outside test for the perforated plate object.
Alpha is used as an indicator here: Alpha = 0.0 if the point is lying outside the physical domain Alpha = 0.0 if the point is lying directly on the boundary Alpha = 1.0 if the point is lying inside the physical domain
Reimplemented from Immersed::Geometry.
