Abstract

A geometrically-based user interface has been developed as a preprocessor for a numerical model of convective heat transfer from printed circuit boards (PCB). The physical problem is specified in a natural way as a collection of the control parameters and the objects that exist within the computational domain. Complicated configurations of discrete electronic components on a circuit board is represented by several simple physical objects with specified boundary conditions and heat-generating status. No reference to node or element number is needed and the input order of the objects can be arbitrary. The preprocessor program automatically sorts the coordinates of each object, subdivides the computational domain, eliminates the redundant coordinates and generates an object grid system that is consistent with the physical configurations of PCBs. This three dimensional geometrically-based object grid system is integrated to the main analysis codes for solving flow and temperature distribution. The geometrically-based model specification provides the hooks for a graphical user interface (GUI) which could be added later.<>

印刷电路板对流换热的数值分析界面

本文开发了一种基于几何的用户界面，作为印刷电路板(PCB)对流传热数值模型的预处理器。物理问题以一种自然的方式被指定为存在于计算域中的控制参数和对象的集合。电路板上分立电子元件的复杂结构由几个具有特定边界条件和发热状态的简单物理对象来表示。不需要引用节点号或元素号，对象的输入顺序可以是任意的。预处理器程序自动对每个对象的坐标进行排序，对计算域进行细分，剔除冗余坐标，生成与pcb物理结构一致的对象网格系统。该三维几何目标网格系统集成到主要的分析代码中，用于求解流动和温度分布。基于几何的模型规范为图形用户界面(GUI)提供了挂钩，可以稍后添加。
