We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

一个物体是不要设置的太薄,否则这种细长条需要很多细网格;

其次,HEAT 仿真缺省情况是绝热边界条件;当你用室温/对流把热量带走后,可能温度就没法建立起来,如你所说全部散出去了。你可以增加一点热功率试一下,热学仿真是线性现象,所以一般情况设置没有什么物体,最关键的是自己设的边界条件是否合适。

你把对流边界改为绝热看看能否建立起温度。
