Analytical solution of three-dimensional equation in partial derivatives of the first order

Under mathematical modeling of problems of flowing around (nonviscous, viscous) tel appears a problem of solutiong the equations of conservation of mass, amounts move-thread and energy. The can be equations Eiler or Navie-Stoks. For solutioning a multivariate parabolic equation [1] there is row the numerical methods of integrating (review in [2]). However practically little numerical methods [1, 3], which generalise on the three-dimensional event and can equally solution equations in private derived first and second order.
In proposed work on the base of operating calculus [4] have been obtained ahalytical formula for the three-dimensional sing-line equation of carrying. Test examples on trial functions have shwon correctness of propouse algorithm and its advantage in contrast wtis numerical technology [3].
