비등각격자면을 갖는 복합재질의 전열해석을 위한 클리핑방법

Abstract

Purpose: As the importance of ecological architecture such as prevention of condensation, thermal analysis with numerical methods became essential in a modern architecture. A grid-based numerical method is widely used, and various grid shapes have been studied. Notably, an unstructured grid has been attracted by means of successful results. Due to the its flexibility of an unstructured grid, it is possible to divide a complex domain into several simple domains in which the grid are generated easily and independently. However, the grid points on the interface between neighbor domains are not matched completely so called non-conformal grid, and thus, the flux between neighbor cells cannot calculate directly. Thus, a technical treatment for the arbitrary interface is required. Method: We employed the clipping method that calculates the connectivity and geometrical information between non-conformal cells on the interface. To validate the clipping method, the heat conduction with a non-conformal interface was performed. Result: The algorithm that we developed represented the interface, and the numerical result agreed with the analytic solution for a heat conduction problem.
