    我需要给定进口总温总压,进口气流速度角度,以及出口静压请问,这么给是否有问题,总是挂。1_1490324845490_U 0_1490324845490_p

    你要很小心设置压力进出口边界条件,从理论来讲这并不是最稳定的边界条件,当然是可以算的并且可以算正确。你用的哪个求解器?网格类型是什么?网格质量如何?把边界条件贴一下?

    @cfd-china 您好,我算的马赫数大约0.6,是一个平面的压气机叶栅,目前用的是simpleFoam,网格用pointwise画的,检查质量ok,但总是挂掉,K,Omega总是超级大。0_1490340380917_1FBQNZ_3CW{X(HG@529NXYB.png

    @cfd-china 用的不可压,只是想尝试算个结果,曾经在fluent中算过,用的komega-sst,湍流模型,看曲线k和omega特别大,达到了10e35量级,2_1490340702077_omega 1_1490340702077_k 0_1490340702077_epsilon 错误信息0_1490340438293_PyFoamRunner.simpleFoam.logfile

    1. 你这个网格哪里调用了交界面边界?抱歉看到了。
    2. 结果从第一步就没有保证连续性
    3. 将网格贴图(而非显示面)
    4. 贴chechMesh结果
    5. 贴fvSolution
    6. 贴fvScheme

    注意是贴哦不是上传附近如:

    我注意到你的log 文件里面从第二个时间步长开始, specific dissipation rate (omega)就已经发散了(10^9)。

    omega 文件里

    FoamFile
    {
        version     2.0;
        format      ascii;
        class       volScalarField;
        object      omega;
    }
    
    你的 internalField uniform $omegaInlet = 630 这个神奇的数字是怎么算的?
    从你的log file 看出,你是从2000 s 开始算的,贴出2000s的初始条件或许能帮助解决问题?
    
    对于你的的进,出口边界条件不是特别理解。用进口速度边界条件,出口用压力边界条件不能满足你的需求吗?气动问题大家通常都是用这个方法。

    @random_ran 我开始没有开湍流模型,想算个初场,2000部之前都是没有湍流模型的,omega用这个公式算的
    omega = k^0.5/(C^0.25 * l) c=0.09
    我的是进口条件是进口已知总压,和气流方向出口知道静压,算出来速度大约是0.67Ma
