The aim of ZJUSIM is automatically building system model describing file from system graph. The software is developed based the theory of finite volume. The component of hydraulic system is displayed by general format such as BMP WMF and GIF etc.

• ZJUSIM软件图形化建模模块的目标是由液压原理图自动生成液压系统的模型描述文件，以节点容腔法为建模理论基础，元件的图形表示以位图(BMP)、元文件(WMF)、GIF等通用格式实现，元件的信息以元件特征表示。
