主要介绍COMSOL Multiphysics 在零维和一维模型数值分析方面的几个关键内容。这些内容包括求根、步进式数值积分、常微分方程数值积分和线性系统分析。这几乎是所有的化工过程数学分析方法。-COMSOL Multiphysics introduces several key elements in the zero-dimensional and one-dimensional numerical analysis model. These include roots, stepping numerical integration, numerical integration of ordinary differential equations and linear systems analysis. It is almost all chemical processes mathematical analysis methods.
