求一个类似于装有液体的圆管温度场模拟算例



  • 想参考后模拟钢包温度场,跪求

    Hi,

    我不是很理解钢包。对于装有液体的圆管温度场模拟,如果圆管厚度不考虑,可以用buoyantSimpleFoam求解,算例参考这个求解器下面的hotRoom,只不过把空气换为液体。如果考虑厚度,需要用chtRegionSimpleFoam,名字可能不太对,大概是这样。

    均在heatTransfer求解器下面。

    Hi,
    在模拟chtMultiRegionSimpleFoam求解器下的multiRegionHeaterRadiation算例时,在执行allrun之后运行chtMultiRegionSimpleFoam求解器,就出现了如下错误0_1461135438468_upload-071a5923-96bb-4b9f-9294-fb7273dde5de ,不知道该怎么解决。

    把你的fvSchemes字典贴上来看看。:boy_tone2:

  • 之前那个问题解决后又出现0_1461572346439_upload-5c98c499-d439-44d1-96ce-31e1b96bbd8a 这个错误,求教submap是什么文件
