数值鼠标技术在凝固模拟中的应用

在凝固模拟技术中，后处理的任务通常是将数值数据可视化，构建出各种直观的三维图形，帮助用户理解数值计算的结果。这个环节在凝固模拟的应用中发挥着重要作用。但是，由于视觉识别对色彩和长度等图形要素定量分辨的精度非常有限，因此，直接从图形上很难准确地解读出所表现的物理函数的精确值。本文采取扩展鼠标光标的形式。将图形上鼠标所指热点单元的函数值，用数值数字直接显示在鼠标光标的扩展序列中，实现了图形函数数值的精确解读，取得了非常好的应用效果，受到用户的好评。

Application of Numerical Mouse in Solidification Simulation

The duty of the post-process in solidification simulation is visualization of the data of calculations. With multiple kinds of pictures, it helps users to understand the simulation results. But because of the limit of distinguishing ability of?human's?eye, it is difficult to get accurate understanding of values of functions by reading from colors of the pictures directly. This paper provides a method to show function values digitally, that is, using expanding space of mouse cursor, display the numerical value of functions dynamically and synchronously along with mouse moving. Application prove, that the method is very effective and is well praised by users.
