Abstract: A method including the steps of: defining an original parent polygon representative domain of interest, an origin corresponding to a wavesource position within the parent, a wavesource wavefront geometry, and a maximum wavefront extent; determining one or more valid parent polygon sides; defining cutting lines from the vertices of each valid parent side to the extent; reflecting the parent about the respective valid side defining a child polygon; discarding portions of each child polygon lying beyond a cutting line from the respective parent side; redefining each child as a parent, and repeating the second to fifth steps for each parent filling the area within the extent; projecting onto the polygons within the extent, a wavefront having the wavefront geometry spaced from the origin by a specified distance; and reflecting the child polygons along the respective sides of their respective parents projecting the child polygons and wavefront onto the original parent.

Abstract: The ultrasonic inspectability of a supplied part out of which a final component is to be machined is determined by following a set of inspection rules for ultrasonic inspection of the supplied part. The rules determine which parts of the polygon cannot be inspected by a scan at a given ultrasound beam angle (typical beam angles are 0°, +20° and −20° relative to the perpendicular direction to the edge) along a given edge of the polygon.

Abstract: Determining magnitude of a field variable of an energy wave through domain of interest, including steps of: defining plurality of master-particles spaced within domain, master-particles being representative of field variables of energy wave at location of respective master-particle, and defining supporting domain Ωm for each master-particle; computing field variables including position, magnitude and direction of propagation of each master-particle at predetermined time; defining plurality of virtual-particles within domain representative of magnitude of field variable of wave at location of respective virtual-particle; calculating magnitude uv of field variable of each virtual-particle at time of interest by applying formula: u v = ∑ m = 1 N   u m  f  ( q   1 ) × g  ( q   2 ) Where   v  ∈ Ω m where N is total number of master-particles, um is magnitude of respective master-particle, f(q1) is an envelope function relating magnitude of virtual-particle to distance from master-particle in direction of propagation of master-particle, and g(q2) is a smoothing function relating magnitude of virtual-particle to distance from master-particle normal to direction of propagation of master-particle.
