本文的目的是提出用于航空数值计算的耦合策略。在第一部分中，使用的基本方法依赖于有限体积Navier-Stokes解算器和有限元实体代码的分区耦合。这两个独立的仿真工具通过耦合库进行交换。两个不同的应用程序演示了这种耦合方法的功能。这种方法的主要优点是，对于每个软件应用程序，都可以从大量专家多年来开发的经验中获益。在第二种方法中，通过为其他学科添加新的简化模块和实现特定的耦合算法，将单学科软件扩展到多物理场建模。文中给出了气动弹性系统的建模以及几个应用，以证明该方法的能力。最后，在第三部分中描述了代码耦合的软件结构。它由一个开放系统方法组成，该方法基于一个强大的开源公共接口集合。
The purpose of this paper is to present coupling strategies for aerospace numerical calculations. In the first part, the basic approach used relies on the partitioned coupling of a finite-volume Navier-Stokes solver and a finite-element solid code. These two separate and independent simulation tools carry out exchanges via a coupling library. Two different applications illustrate the capabilities of this coupling method. The main advantage of this approach is to benefit, for each software application, from the experience developed by a large number of specialists over many years. In the second approach, mono-disciplinary software is extended to multi-physics modeling, by adding new simplified modules for other disciplines and by implementing specific coupling algorithms. The modeling of aeroelastic systems is presented as well as several applications to demonstrate the capabilities of this method. Finally, a software structure for code coupling is described in the third part. It consists of an Open System approach, based on a powerful open source assembly of public interfaces.
