WebAVL is a program for the aerodynamic and flight-dynamic analysis of rigid aircraft of arbitrary configuration. It employs an extended vortex lattice model for the lifting surfaces, together with a slender-body model for fuselages and nacelles. General nonlinear flight states can be specified. The flight dynamic analysis WebFlow Sets. In dataflow analysis, we seek to associate some data with each node in the control-flow graph. In Soot, we represent this data as flow sets. Typically, a flow set represents a set of facts. For reaching definitions, the flow sets are the sets of pairs (variable, program point). Soot defines the FlowSet interface to be the canonical ...
