I would like to share my PINN-libtorch code for cavity flow. It can be compiled in the environment of OpenFOAM-8,9,10,11, etc. Please see the following: Code: #include <torch/torch.h> using namespace std; //创建神经网络 struct NN : torch::nn::Cloneable<NN> { torch::nn::Se...
为了加速气固两相流的模拟计算,使用卷积长短时记忆网络对物理量进行预测,并基于LibTorch实现深度学习模型预测与OpenFOAM的耦合。通过与单纯OpenFOAM模拟结果对比,发现深度学习模型预测存在颗粒体积分数不守恒、极小数值预测不准确的问题,先后通过体积分数校正和网格数据过滤消除了前述影响。选取不同的三个物理量组合进行深度...

Since version 1.3 of PyTorch, there is a version of libtorch compiled with ABI enabled ([read more](https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html)). However, it is still necessary to build the OpenFOAM sources because the compiler version in the default centOS-based...
Dockerfile.no_abi: OpenFOAM is compiled from scratch with modified compiler flags to be compatible with libtorch versions prior to version 1.3By default, the OpenFOAM library will be compiled running two jobs in parallel. If you prefer to use more jobs, set the NP build argument, e.g.:doc...
