    半新手,看其他论坛上可以实现这样的操作,即把一个复杂的几何体分成多部分分别划分网格之后再进行拟合,但是我自己试了下建块merge后导入到fluent中出错,请问该如何操作呢?不胜感激

    @Yung 这个 CAD 可以导出的格式有点少呀,0b3894d9-c7b1-4e5a-b38a-a1907754d22a-image.png ,输出-其他格式里面我这个版本只有这几个,你可以试一下 *.stl,*.igs不过我都没用过,不确定到底可不可以。

    业内基本是公认的单通道多通道对CFD影响很大

    不过我还没自己实测过,所以不敢说100%,只敢说98%

    I want to keep my bike close by, so I can fix it

    I want to take off (remove) the bike wheel

    Allen key

    It doesn't fit

    Move over, scoot over, can I get passed, please

    She likes more and more like me everyday

    I rarely (don't often) watch TV

    Why did you set the temperature to 20 degrees

    Dont rush me

    I want to get rid of the extra oil

    I can take some, I will finish what's left

    She has a loose tooth, and its goin to fall out

    She is not fully awake, she is a bit groggy

    She is the one who loves me the most, she loves me the most

    Put on the striped onesie

    Move forwards and backwards

    Her ton nail is broken

    This is her first time seeing it

    This drink is non-alcoholic, you can have a sip

    Take a big step forward

    A loose thread

    Lift my leg and put it down

    Stick out your tongue

    She is lying on her side

    I did it all in one go

    Do you mind if I add her to our chat?

    Please comment on the sentences above

    Look at the lines on your arm. You leaned against something, that left lines on your arm.

    Pull the handle to open the wardrobe

    She just wants to be held up one your shoulder, she just wants to be held close to your chest

    I am afraid of the dark

    When she is sleeping, how does she know who is beside her

    She does not care about anything, she is not easily bothered by things, she has high tolerance. I have a high pain tolerance.

    If someone's ideas can be easily influenced by others,

    She does not want to lean back

    Give yourself a round of applause

    Candy wrapper

    I am meshing the pataya???

    Are u scared of mosquitoes biting you?

    Do you hear me calling you?

    Another spoonful

    How about I weigh you?

    @liujuncfd 这恐怕不行吧,比冲是推力除以单位时间消耗燃料的质量(或重量)。

    请问在Starccm中设置物体的亲水还是疏水材料时是定义表面张力还是接触角呢,我在定义气水两相时,定义了表面张力数值,但是固体边界处有个接触角,默认是0弧度,请问要修改这个数值吗

    近壁面网格长宽比本来就很大,如果用RANS计算,有的模型对近壁面y+要求很小,比如SST k-omega要求y+≈1,但是对x+或者z+基本没有明确的限制,为了减少网格数量,一般流向和展向的网格无量纲参数可以在百千量级,这样的话近壁面网格长宽比就会很大,也是可以正常计算的。
