刚学ansys才一个月,见笑了,上面的命令流,有个问题,就是在二冷区的时候,是接着上面刚加完热流密度的边上,在加上对流这个边界载荷,我使用了表面效应单元(不知道,用的对不对),但总是报错,不知道为何?
请各位大侠帮看看啊,谢谢 你要解决的问题是什么？想得到什么结果？
你的程序在我的机器上运行时，ansys直接关闭，在检查一下你的程序。
另：对于连铸这么一个复杂的过程，你简化得也太狠了。

我想模拟出温度场,但不太会,我的确简化了不少条件,我刚接触这方面,不太会!我初步是这样考虑的,在结晶器中(不知道用ansys如何来处理气隙)只加热流密度,在二冷加对流,然后就是辐射.
你对这方面了解吗?可以和你交流一下吗?QQ122189123
