@李东岳上面的步骤是在编译MomentumTransportModels文件夹时候的。同时，我在simpleNNFoam中修改了我的需要连接的linearViscousStrees中的divDevTau(U, S, R)，S跟R都已经在 createFields.H中创建了。

    // Momentum predictor

    MRF.correctBoundaryVelocity(U);

    tmp<fvVectorMatrix> tUEqn
    (
        fvm::div(phi, U)
      + MRF.DDt(U)
      + turbulence->divDevTau(U, S, R) // Data driven R-S + viscous component
     ==
      fvModels.source(U)
    );
    fvVectorMatrix& UEqn = tUEqn.ref();

    UEqn.relax();

    fvConstraints.constrain(UEqn);

    if (simple.momentumPredictor())
    {
        solve(UEqn == -fvc::grad(p));

        fvConstraints.constrain(U);
    }

但是我在wmake我的simpleNNFoam中出现了，数据类型不对的问题。

我查看了 Foam::data::data(const objectRegistry& obr)，要的是objectRegistry类，但是在我的reynoldsNet库中已经将libtorch输出的torch::Tensor转换成std::vector<float>然后带入输出，没有将是torch的数据直接带入OF中。这是有数据没按要求来转换吗？
