为什么改变环境温度却不改变计算结果？
我觉得环境温度变化了，热膨胀位移和作用力、应力都会改变。所以结果应该按照改变后的环境温度而不是70度来计算。


Why is not results being changed when using menu "Tools-Configure/setup-Computational Control-Default Ambient" to change the ambient temperature into 100F?
I think the ambient temperature change to not 70F, the thermal expansion displacement,the force and stress will change. so result should be calculated according to the changed ambient temperature but not 70F.
