《多物理场仿真:数值要领及工程运用》本书由英特仿真总裁 张群 博士取清华大学 岑松 传授配合编著,是世界上首部多物理场耦合仿真技术及运用专著,由Elsevier取“清华大学出版社”结合出书,现做为清华大学盘算力学系教科书运用。
书中具体引见了工程中常见的构造、流体、温度、电磁、噪声等物理场间的耦合题目,叙述了强耦合要领、强耦合要领和跨顺序之间的耦合要领。对差别耦合边界条件及其数值实现要领停止了深切议论,触及流—固耦合、流—固—温度场耦合、电磁—流—固—热耦合等庞大耦合题目。书中还枚举了汽车工程、航空航天工程、扭转机器、微机电体系、生物医学工程等范畴的20多个现实耦合剖析案例。《多物理场仿真:数值要领及工程运用(英文版)》供应了从耦合实际、要领、软件开辟到工程理论的较为周全综合的常识和工程理论系统,可供相干学科和行业的科研人员、工程技术人员、软件开发人员浏览参考,也可作为理工科相干课程的研究生课本。

Constitutive—equation coupling: the primary variable or output of one field influences the material properties or the constitutive equations of the other physics models.
Analysis—domain coupling: a field.usually the structural field, provides displacement boundary conditions for the nonstructural field to influence their analysis domain.
2.4.2 Coupling types by non/inearity:
strong and weak coupling
Based on the level of' nonlinearity caused by the coupling, coupling problems can be classified into SC problems with high nonlinearity and weak coupling problems with low nonlinearity.
For a coupled .system with high correlation between physics models, such as FSI problems with incompressible fluid enclosed by soft structure, FSI problems with structural buckling, or with discontinuous shock wave in CFD field, the nonlinearity of the system is high.This kind of coupling is referred to as an SC problem.

If the dependency between physics models is weak and the nonlinearity of a coupled system is not critical, it is considered as a weak coupling problem, for example,standard thermal—stress coupling problem without highly nonlinear temperature dependent material behavior, fluid—structure problem with high structure stiffness and low Reynolds number flow in an open domain, etc.
