In this paper we propose a regionally-structured method for identifying nonuniform temperatures of a construct surrounding an environment under high speed thermal processes with oscillating heat exchange. It is built regional- analytical structure of the solution of tasks accurately satisfy high-speed oscillating heat transfer to the border areas of the complex doubly connected domain at any given time depending on the ambient temperature and relative heat transfer coefficients. Regionally-analytical structures of problem solving were built, these structures accurately satisfy high-speed oscillating heat transfer on boundary areas of the complex doubly connected areas at any given time-depended environment temperature and any relative heattransfer coefficients. The structures of these solutions allow for displays of simulated results and regionally-analytical prediction of high-speed oscillating thermal processes on agreed displays in real-time. The use of S-functions in the structures of solutions for the inclusion of information about the area geometry for the first time makes it possible to construct continuously differentiable basis functions in the approximate regional-analytical problems of high heat transfer.
