转子热应力有限元前后处理方法

Pre and Post-Processing in Finite Element Analysis of Turbine Rotor Thermal-Stress

结合汽轮机转子热应力有限元分析问题，提出了适用于汽轮机转子有限元热应力分析的前后处理可视化的实现方法。前处理主要包括原始几何模型的输入、有限元网格的自动生成，后处理包括二维温度场应力场等值线、云图、结果时间趋势图的绘制方法等。

Based on the advanced computer visualization technique the pre and post -processing of finite element analysis of turbine rotor thermal-stress are conducted. The pre-processing includes data input and automatic mesh creation on two dimension region. The post-processing includes computer drawings of isothermal and stress fields, color contour image and trend curves.
