BOUNDARY CONDITION SETTING METHOD FOR STRUCTURE ANALYSIS MODEL

摘要

PROBLEM TO BE SOLVED: To extract an element in a part corresponding to a surface coming into contact with an internal space of a structure in a structure analysis model in a short time in setting data of a fluid analysis model created concerning a fluid of the internal space in the structure analysis model created concerning the structure having an open part opened to the outside and the internal space which the fluid flows in and out through the open part.;SOLUTION: Out of all elements in the part corresponding to the surface coming into contact with the internal space of the structure in the structure analysis mode, an optional element in the part corresponding to the vicinity of the open part to the structure outside in the internal space is set as a reference element (step S22), and with the reference element taken as the kernel in the structure analysis model, the adjacent elements in the part corresponding to the surface coming into contact with the internal space are extracted one after another as the boundary condition setting object elements (step S25).;COPYRIGHT: (C)2009,JPO&INPIT
