Nvidia has opened the source code Physx and Flow

Since the release of Physx SDK 4.0 in December 2018, NVIDIA Physx has been available with an open source for BSD-3 license-with one key exception: the source code of the GPU modeling nucleus was not turned on.

recently NVIDIA reported that the latest Physx SDK update now includes the entire source of GPU, completely Licensed by BSD-3. With more than 500 CUDA nuclei, providing functions such as solid dynamics, fluid modeling and deformable objects, GPU Physx is one of the most advanced method of using the modeling in real time of CUDA and programming GPU.

In addition, the company also opened the source code of the computing shader GPU Flow Flow SDK, Libraries of fluid modeling in real time based on a sparse grid.

The source code of Physx and Flow can be found on Github.
