摘要
介绍了普遍存在的多物理场场耦合问题。首先,给出了几个主要且常用物理场的数学描述,讨论了它们之间的场耦合关系,进而研究了多场耦合的建模问题。对电子装备中存在的多场耦合及其建模问题作了专门论述。其次,介绍了多场耦合问题的求解策略与方法,涉及到不同场网格之间的匹配、滑移及信息传递等问题。再者,阐述了多场耦合优化设计问题,给出了一种多场耦合问题的优化设计模型。
The coupled multi-field problems （CMFP） existed widely in science and engineering is discussed in this paper. First of all, the mathematical descriptions of important and typical fields are given, in which the coupling relations are considered, then the model for CMFP is studied. The CMFP and its model in electronic equipments are proposed technically. Secondly, the strategies and methods for solving CMFP are investigated in detail, considering the problems of non - matching and moving grids in different fields, transferring data as well. Finally, the problem for designing optimization of CMFP is considered, the model for CMFP＇s optimization is proposed too.
