本文概述了连续介质力学现场操作与操纵（FOAM）C++类库的原理。我们的目的是尽可能容易地开发可靠和有效的计算连续力学代码：这是通过使代码的顶级语法尽可能接近传统的数学符号，张量和偏微分方程来实现的。面向对象技术使得能够创建与连续介质力学非常相似的数据类型，并且C++中可能的运算符重载允许将正常的数学符号用于基本运算。作为一个例子，在FOAM计算流体动力学代码中的各种类型的湍流模型的实施进行了讨论。并对一个标准的试验情况，即绕方柱的流动进行了计算。为了证明FOAM库的灵活性，代码解决结构和磁流体力学也给出了适当的测试用例结果。(C)1998年美国物理学会。[S0894 - 1866（98）01906 - 3]。
In this article the principles of the field operation and manipulation (FOAM) C++ class library for continuum mechanics are outlined. Our intention is to make it as easy as possible to develop reliable and efficient computational continuum-mechanics codes: this is achieved by making the top-level syntax of the code as close as possible to conventional mathematical notation for, tensors and partial differential equations. Object-orientation techniques enable the creation of data types that closely mimic those of continuum mechanics, and the operator overloading possible in C++ allows normal mathematical symbols to be used for the basic operations. As an example, the implementation of various types of turbulence modeling in a FOAM computational-fluid-dynamics code is discussed. and calculations performed on a standard test case, that of flow around a square prism, are presented. To demonstrate the flexibility of the FOAM library, codes for solving structures and magnetohydrodynamics are also presented with appropriate test case results given.
