Implementace paralelního algoritmu pro výpočet solární radiace do konečně-prvkového řešiče ESPRESO

Abstract

The solar radiation problem is one example of a heat conduction problem. In it, we examine the temperature of an object that receives solar radiation. This problem can be solved using the finite element method. To use this method, we need to calculate how much of the surface area is covered by light and how much of the surface area of the object is covered by shadow. For this purpose, an algorithm for calculating the shaded and illuminated parts of the object surface is presented in this paper. Furthermore, the parallelization method of the algorithm is presented. The algorithm has been implemented for use in the massively parallel solver ESPRESO.
