求助，为什么底部和中间最靠外物体的温度都是一样的？

andylau436

这是我的钢包（储存钢水的容器）的命令流，问题是，圆柱体最外一层和中间耳轴（图中蓝色部分）材料都是钢，底部支撑也是钢，一样的材料，都设定了对流系数，但是结果是，这2个部分（温度分布图中蓝色的两个部分）都是30度，说明圆柱外壳的温度没有传到蓝色部分区域，这是为什么呢？希望高手可以给我指点一下，命令流和温度分布图如下，小弟再次先谢了！

tonnyw

我认为模型可以简化，只取四分之一即可，当然前提条件是边界条件也是对称的。你是否可以解一下动力分析问题，只求四五个固有频率，然后看一下振型，看看有没有单元飞出去，以检查单元划分有无问题。

andylau436

tonnyw，你好，我的模型大体上是可以简化成1/4模型，但是底部有点不对称，因为下面还有几个不同结构，他们是不对称的，所以我没有简化，另外你说的通过动力分析求振型，以验证单元划分有无问题？如何来做，我没有做过，我只是做热分析，结构分析两个模块，你可以帮我验证一下吗？我想加你的qq，请问你号码的是？我的是404792373

tonnyw

很抱歉，我很忙。你也可以使用不同的方法，来测试你的模型，比如说壳体的一半绝热，一半设置对流边界条件，你就知道热量肯定向对流边界流动。蓝色的部分没有温度变化，是否导热系数太小所致？你也可以使用正交各向异性材料，将一个方向的导热系数设得很小，使热量朝你所指定的方向流动。虽然你的底部不对称，你不妨先取上部的一半做对称分析，看看到底是什么地方出了问题？

andylau436

好的，谢谢你得提醒，我自己去试一试！
