ANSYS多圈管2D冻结温度场分析，根据对称性，选择第一象限进行模拟。 命令流中有详细说明！ ZTIME=540           !冻结时间 Ld=10000            !如果某荷载步的温度等于Ld，则表示该荷载步不加载，直到下一荷载步 KBCVALUE=1          !KBCVALUE=0为坡道加载,KBCVALUE=1为阶跃加载 THETA=90            !所计算扇形区的圆心角,单位为度。一般取为第一圈孔的主面与界面的夹角（保证井内温度场基本不受影响）                     !该范围内每圈孔至少有3个管，否则可能在捕捉图时有点小问题, GA=THETA*1/1        !应确保GA的范围内每圈冻结管至少有2个.

说明：  4. Analysis of ICC color management technology principle
