高压SF6断路器气流场求解的问题
请教各位大侠，SF6断路器中的气流场是变粘性，变密度，跨音速，具有湍流，激波的流体，我现在想求解触头在不同开距下的速度，密度等的等值线图，请大家帮忙看看我设置流体特性的命令流哪里错了fldata12,prop,ufrq,10 !设置特性更新频率的标志fldata12,prop,ivis,10
fldata13,vary,dens,t !设置气体特性变化标志
fldata13,vary,visc,t

!限制速度峰值

现在一求解就出现温度负值，郁闷啊！

你的程序流不全呀可以把前边的也贴出来
我看看,怎么办呀

求解控制flda,meth,pres,1 !三对角矩阵求解压力
flda,meth,temp,1
flda,meth,enke,1
flda,meth,ends,1
是不是应该是fldata18呀,而且除了pres的求借器外其他都是默认的
!提高收敛性和稳定性的工具，惯性松弛的设置
fldata26,stab,turb,1
fldata26,stab,pres,0.2 !压力松弛因子
fldata26,stab,mome,0.2 !动量松弛因子
松弛因子好象比默认只大好几个数量机呀,
这个数值怎么确定呀,很大的
t是不是在前边定义的参数呀
可以多多交流呀

希望大家给点建议，我的程序流文件现在结果不正确，我不知道错在那里，温升过高，发散！不过我认为模型的建立和剖分很不错哦！我希望我们能共同进步！同时谢谢斑竹的加分鼓励。
