Description

In large scale linite element (FE) analyses of over ten millions degrees of freedom (DOFs), it is very difficult not only to calculate but also to visualize them. This difficulty in visualization is mainly caused due to the following two reasons. Firstly, verification for large-scale analysis requires highly Interactive user interface. Secondary, it can not be handled on a conventional single processor machine any more. This paper describes a prototype of the visualization system for large scale FE solutions with millions of DOFs using a virtual reality environment named CABIN for the former issue and a PC-based cluster consisting of 24 PEs (DEC Alpha 533 MHz) for the latter issue. CABIN provides a large scale and realistic space in immersive multiscreen display. This makes it easy to understand the results, but requires excessively computer resources. Thus we employ the PC-based cluster, which supplies the processed data to the front-ended CABIN system. Practical performances of the present system are demonstrated for both three-dimensional elastic and fluid flow analyses.
