Based on RPC semantic and agent-oriented software bus, a task-level-paralle
l Distributed-Object-Computing model has been designed to have complicated
numerical analysis and Visualization in Scientific Computing(ViSC) for TWT-
CAD, while making use of object-oriented technology and thread-concurrence
technology. The ViSC software running on a Windows NT LAN(Local Area Networ
k) for beam-wave interaction of TWTs has been developed in Visual C++, of w
hich software architecture and key technologies are given in the paper.
