Si Fly Flight 3275 were found in good condition. Analysis from the crash site concluded that the plane struck tree tops first before impacting terrain. The first impact occurred 15 metres from the top of a ridge, in a rocky mid-mountain area. During the impact, the fuselage and wing disintegrated, the fuel ignited, and an explosion occurred. The French BEA then collected weather data prior to the crash. From Slovenia to Greece and from Italy to Bulgaria, the winds at altitude were very weak from the north. They were sufficient to create a foehn effect under the mountain winds that left the whole coast
Dirichlet boundary condition and are given numbers. For a partial differential equation, for example, where denotes the Laplace operator, the Dirichlet boundary conditions on a domain take the form where is a known function defined on the boundary . For example, the following would be considered Dirichlet boundary conditions: Many other boundary conditions are possible, including the Cauchy boundary condition and the mixed boundary condition. The latter is a combination of the Dirichlet and Neumann conditions. Dirichlet boundary condition In mathematics, the Dirichlet (or first-type) boundary condition is a type of boundary condition, named after Peter Gustav Lejeune Dirichlet (1805–1859). When imposed on
