@李东岳在 OpenFOAM libtorch tutorial step by step 中说：

net.H

#include <torch/torch.h>

class NN
:
    public torch::nn::Module 
{
    torch::nn::Sequential net_;

public:

    NN();

    torch::Tensor forward(torch::Tensor x);
};

net.C

};

torch::Tensor NN::forward(torch::Tensor x) 
{
    return net_->forward(x);
}

这个要编译成库，挂到PINNFoam上面

李老师请问这个如何编译并挂载呢可以详细的指导一下吗

想模拟一个二维数值波浪水池里规则波与液箱的相互作用问题。
求解器用的是waveDyMFoam ,属于interFoam里的二相流求解器。
不知道如何设置边界条件。
刚开始把水箱的外表面设为wall1,内表面为wall2，两者的边界条件如下：
P：fixedFluxPressure;
V：movingWallVelocity;
alpahwater:zeroGradient
pointdDisplacement: calculated;
Dynamicdic设置没有问题。
结果跑不起来。
我又把内边界wall2的边界条件改为：
V：
PointDisplacement：fixedValue

V：fixedValue
其余不变，结果还是跑不起来。
请问有大神知道哪里出了问题吗？感激不尽
