自主CAE平台及计算力学软件研发新进展

数值模拟是求解复杂工程问题强有力的工具.科学计算程序的一大需求在于复杂及可变数据结构的存储、提取和处理能力.对于用户而言,不仅需要强大的求解器,还需要良好的图形交互界面,因此,开发具有通用性和开放性的CAE软件平台和友好的用户界面势在必行.本文在介绍CAE软件平台OmtDesk的基础上,采用C++语言和面向对象软件开发技术,建立了高效CAE平台,解决了CAD模型与计算力学平台接口、网格生成、大型数据存储、快速求解算法等关键问题;同时基于Qt+OpenGL技术,开发了跨系统的友好图形用户界面;最后,以固体力学数值模拟为例,基于该平台和用户界面,开发了计算固体力学专用软件.由此可见,本文提出的软件设计理念是有效的,实现的CAE平台已经拥有了强大的功能. 

New Development of CAE Platform and Computational Mechanics Software

Numerical modeling is a powerful tool to solve complex engineering problems. One of significant requirements in the design of a scientific computing program is the ability to store, retrieve, and process data that maybe complex and varied. To the users, it is important not only to have a powerful solver, but also to work in a convivial graphical interface environment. It is so important to develop a general and open CAE platform with friendly graphical user interfaces. This paper presents the new progress of our research team in developing the CAE software platform OmtDesk. Using Qt+OpenGL and C++ Object-Oriented Programming (OOP) techniques, this platform includes a friendly User Graphical Interface (GUI) and it could be run on multi-systems. As an example, a solid mechanics computational software is developed based on the platform and user interface. It shows that the software design concepts proposed in this paper are valuable and the CAE platform has already powerful features.
