Internally, we have attempted to write the underlying algorithm so that the code runs as fast as possible for the configuration chosen by the user --- from simple two-dimensional setups to complex three-dimensional simulations --- and so that as much code as possible is shared between the different architectures, models, and grids. Note: The latest version of Oceananigans requires at least Julia v1.6 to run. Installing Oceananigans with an older version of Julia will install an older version of Oceananigans (the latest version compatible with your version of Julia).

unity unity3d gpu shader compute fluid-dynamicsThis project is based on the excellent article Interactive Terrain Modeling Using Hydraulic Erosion. The Authors were also kind enough to publish the code in ShaderX7 which is what a lot of this Unity project is based on. I have made some changes and left some things out. The idea behind this project is to erode a height map through a series of natural processes to help create a more realistic height map. Three processes are applied to the height map each frame and can be classed as force-based erosion, dissolution-based erosion and material slippage. All of these processes are carried out on the GPU. The height map can be represented by a series of layers (4, one for each RGBA channel) and each can have different erosion settings applied to it. The lower layer represents the base rock layer and the top layer represents soft soil/sand were any sediment is deposited.

There the grid can also be non-uniform (e.g. fine at the boundary and coarser in the center). CaNS now allows for choosing an implicit temporal discretization of the diffusion term of the N-S equations. This results in solving a Helmholtz equation for each velocity component. Since FFT-based solvers are also used, the same options described above for pressure boundary conditions apply to the velocity, in case implicit diffusion is used.

The code is open-source and developed by a team of researchers studying astrophysical and geophysical fluid dynamics. Dedalus is written primarily in Python and features an easy-to-use interface with symbolic equation entry. Our numerical algorithm produces sparse systems for a wide variety of equations and spectrally-discretized domains. These systems are efficiently solved using compiled libraries and are automatically parallelized using MPI.

fluid-dynamics computational-fluid-dynamics aerodynamics aeronautics linear-theory potential-flowFluids is open-source software for engineers and technicians working in the fields of chemical, mechanical, or civil engineering. It includes modules for piping, fittings, pumps, tanks, compressible flow, open-channel flow, atmospheric properties, solar properties, particle size distributions, two phase flow, friction factors, control valves, orifice plates and other flow meters, ejectors, relief valves, and more. The fluids library is designed to be a low-overhead, lightweight repository of engineering knowledge and utilities that relate to fluid dynamics.

NeqSim Python is a Python interface to the NeqSim Java library for estimation of fluid behavior and process design for oil and gas production. NeqSim Python toolboxes (eg. thermoTools and processTools) are implemented to streamline use of neqsim in Python. Examples of use are given in jupyter workbooks. See the NeqSim Python Wiki for how to use NeqSim Python via Python or in Jupyter notebooks. Also see examples of use of NeqSim for Gas Processing in Colab. Learn and ask questions in Discussions for use and development of NeqSim.
