雙折射材料的溫度修正 Birefringent Material Temperature Modification SyI#Q[f'_ B4%W,F:@ 目前,FRED尚不支持“global”溫度設(shè)置,溫度敏感性評估一般用腳本編程來完成,該文檔演示雙折射材料的折射率隨溫度變化的問題。附件案例文件包括兩個(gè)雙折射材料模,“KDP”和 “KDP Baseline”, KDP Baseline材料存儲(chǔ)在已知溫度下的折射率,KDP材料用于儲(chǔ)存在“current”溫度下的折射率值,定義為與baseline material之間的溫度差。一個(gè)嵌入的腳本名為“modifyBirefringentMaterialIndex” ,包含在FRED文件中,另外也單獨(dú)附加。其實(shí)現(xiàn)過程如下: ~O!v?2it8q [1Rs~T" 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline tG'c79D\ 2]|+.9B 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 5^qI6
