On the shape of a set of points in the plane

WebPartition of unity finite element method with plane wave enrichment (PW-FEM) uses a shape function with a set of plane waves propagating in various directions. For room acoustic simulations in a frequency domain, PW-FEM can be an efficient wave-based prediction method, but its practical applications and especially its robustness must be … WebIn particular, points, lines, and planes are all geometric concepts that relate to positions in space and provide a starting point to defining all other geometrical concepts. Fundamentally, we start with a point. A point is a location in space that has neither shape nor size. However, in order to be able to model this concept, we use a small ...
