商品描述
This book presents the theory of continuum mechanics for mechanical, thermodynamical, and electrodynamical systems. It shows how to obtain governing equations and it applies them by computing the reality. It uses only open-source codes developed under the FEniCS project and includes codes for 20 engineering applications from mechanics, fluid dynamics, applied thermodynamics, and electromagnetism. Moreover, it derives and utilizes the constitutive equations including coupling terms, which allow to compute multiphysics problems by incorporating interactions between primitive variables, namely, motion, temperature, and electromagnetic fields.
An engineering system is described by the primitive variables satisfying field equations that are partial differential equations in space and time. The field equations are mostly coupled and nonlinear, in other words, difficult to solve. In order to solve the coupled, nonlinear system of partial differential equations, the book uses a novel collection of open-source packages developed under the FEniCS project. All primitive variables are solved at once in a fully coupled fashion by using finite difference method in time and finite element method in space.
商品描述(中文翻譯)
本書介紹了連續介質力學的理論,適用於機械、熱力學和電動力學系統。它展示了如何獲得控制方程,並通過計算現實來應用這些方程。本書僅使用在 FEniCS 專案下開發的開源代碼,並包含來自機械、流體動力學、應用熱力學和電磁學的 20 個工程應用的代碼。此外,它推導並利用了包括耦合項的本構方程,這使得能夠通過納入原始變數之間的相互作用來計算多物理場問題,這些原始變數包括運動、溫度和電磁場。
一個工程系統由滿足場方程的原始變數描述,這些場方程是空間和時間中的偏微分方程。場方程大多是耦合的和非線性的,換句話說,難以解決。為了解決這個耦合的非線性偏微分方程系統,本書使用了一套新穎的開源套件,這些套件是在 FEniCS 專案下開發的。所有原始變數都是一次性以完全耦合的方式解決,使用時間上的有限差分法和空間上的有限元素法。
