“原生访问”这个说法怎么样呢?
真正的native access应该指前处理软件不仅能读取cad模型,并且能完整地保留其特征和参数。除此之外,cae仿真对于模型验证、优化的结果也能反映到cad文件中。
我觉得目前abaqus cae的associative interfaces做的还是不错的,毕竟它和catia、solidworks都是达索的产品了。
The associative interfaces are optional add-on products that simplify the process of transferring model data between third-party CAD systems and Abaqus/CAE. The associative interfaces use the CAD Connection toolset to create a connection between Abaqus/CAE and a CAD system running an associative interface plug-in. Associative interface plug-ins are available for the following CAD systems:
- CATIA V5
- NX (Unigraphics)
- SolidWorks
- Pro/ENGINEER
The associative interfaces allow for associative import of models from a CAD system to Abaqus/CAE. You can export an entire assembly from the CAD system into Abaqus/CAE with a single mouse click, and you can modify your model in the CAD system and use the connection to quickly update the model in Abaqus/CAE. Features that you created in Abaqus/CAE—such as loads, boundary conditions, sets, and surfaces—are updated when you import the modified model. In addition to modified parts, any changes that you make to the position of instances in the assembly will also be exported to Abaqus/CAE.
记得abaqus板块有关于proe、solidworks对abaqus接口的讨论,楼主不妨搜一搜。 其他的前处理,patran可以读取catia等cad文件,但貌似都是转换成parasolid导进去的;ansa也可以读取主流cad文件,但也是通过转换成ansa格式导入的;hypermesh倒是不清楚了。 总而言之,目前cae前处理软件对主流的cad格式catia、ug、proe、solidworks都能读取,但肯定是不如abaqus/cae的associative interfaces更加native了。
大家仁者见仁,智者见智。我就算抛砖引玉了。
