基于Fluent二次开发地铁通风系统日志文件 总被引:1,自引:1,他引:0
空调设计工程师应用Fluent软件对地铁空调通风系统进行数值分析仿真过程中遇到了诸多问题,如:重复性工作多、对使用者的流体专业知识要求过高等,通过Visual Basic高级编程语言编译仿真平台,调用Journal参数化日志文件,可以解决此类问题.参数化日志文件的应用是对Fluent软件进行二次开发的重要方法,不仅能够提高工作效率而且降低使用者门槛.本文研究内容:1)重点研究了Gambit与Fluent软件的命令流文件(Journal日志文件)的编写方法.2)Gambit与Fluent软件能够根据输入的参数对车体模型自动参数化建模、自动进行数值仿真计算并保存后处理结果.3)Journal日志文件在计算过程中能灵活地实现CFD分析中的相关功能,并且能够对计算结果与实验数据进行对比.因此, Fluent二次开发在实际工程上有着非常广阔的应用前景. 相似文献

由于市政工程设计的行业特点,导致现有参数化设计手段应用范围受限、编程开发效率低下。为此二维参数化设计软件ParaCAD另辟蹊径,采用以自定义参数化构筑物为中心的平台化开发应用模式,实现定义系统和使用系统的分离,形成开发人员、定义人员和使用人员三方互相合作促进的参数化生态体系。ParaCAD还通过高效的参数化公式联动、简便的可视化编辑操作和无副作用的定义过程模型等关键技术组合创新,有效地提高了参数化构筑物的定义效率。在该平台上已进行了大量参数化构筑物的定义实施工作,达到了相关专业构筑物基本覆盖的目标,同时在实际工程项目中推广使用已发布构筑物进行设计出图,取得了很好的应用成效。 相似文献

为解决应用ANSYS软件进行变参数工程仿真时经常遇到的操作效率低、参数修改不够灵活等问题,提出了一种新的综合仿真方法。该方法将界面输入和命令流输入两种操作方式有机地结合起来,以分步图形用户界面(GUI)操作得到的ANSYS参数优化设计语言(APDL)源代码作为模板,再批处理相似代码,将定值命令流更改为变参数命令流。当开发者再次遇到相似操作时,只需修改关键参数即可完成仿真。实践证明,该方法大大提高了仿真效率,对ANSYS工程仿真操作具有一定的指导意义。 相似文献

在工艺开发包的验证过程中,需要手动地在版图编辑器中对参数化单元进行实例化和摆放绕线,由此产生大量测试芯片。为此,提出一种用于验证工艺开发包的测试芯片自动生成流程,采用软件接口产生Skill脚本和工艺开发包交互,以获取工艺开发包的信息、发送命令对工艺开发包进行操作的方法,能自动地对参数化单元予以实例化,自动地摆放绕线,并实现测试芯片版图的布局规划。用该软件接口针对某代工厂的40 nm半导体工艺开发包开发一套测试芯片,产生一条测试芯片的平均时间为5.2 s左右,结果证明该方法是有效的,能缩短工艺开发包的验证时间。 相似文献

This paper presents engineering decision-making on pipe stress analysis through the application of knowledge-based systems
(KBS). Stress analysis, as part of the design and analysis of process pipe networks, serves to identify whether a given pipe
arrangement can cope with weight, thermal, and pressure stress at safe operation levels. An iterative process of design and
analysis cycle is done routinely by engineers while analyzing the existing networks or while designing the process pipe networks.
In our proposal, the KBS establishes a bidirectional communication with the current engineering software for pipe stress analysis,
so that the user benefits from this integration. The stress analysis knowledge base is constructed by registering the senior
engineers’ know-how. The engineers’ overall strategy to follow up during the pipe stress analysis, to some extent contained
by the KBS, is presented. Advantages in saving engineering man-hours and usefulness in guiding experts in pipe stress analysis
are the major services for the process industry.
