WA physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics, soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film (CGI). Their main uses are in video games, in which case the simulations are in real-time. The term is sometimes used more generally to describe any software system for simulating physical phenomena, such as high-performance scientific simulation.

WCUDA is a parallel computing platform and application programming interface (API) that allows software to use certain types of graphics processing unit (GPU) for general purpose processing – an approach called general-purpose computing on GPUs (GPGPU). CUDA is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels.
WDigital Molecular Matter, better known as simply DMM, is a proprietary middleware physics engine developed by Pixelux for generating realistic destruction and deformation effects. The offline version can support high-resolution simulations for use in movie special effects. The real-time version is designed for computer, video games, and other simulation needs by attempting to simulate physical real-world systems. Unlike traditional realtime simulation engines, which tend to be based on rigid body kinematics, the use of finite element analysis (FEA) allows DMM to simulate a large set of physical properties. Developers can assign physical properties to a given object or portion of an object, which allow the object to behave as it would in the real world. In addition, the properties of objects or parts of objects can be changed at runtime, allowing for additional interesting effects.
WHavok is a middleware software suite developed by the Irish company Havok. Havok provides a physics engine component and related functions to video games.

WOE-Cake, OE-CAKE! or OE Cake is a 2D fluid physics sandbox which was used to demonstrate the Octave Engine fluid physics simulator created by Prometech Software Inc.. It was one of the first engines with the ability to realistically process water and other materials in real-time. In the program, which acts as a physics-based paint program, users can insert objects and see them interact under the laws of physics. It has advanced fluid simulation, and support for gases, rigid objects, elastic reactions, friction, weight, pressure, textured particles, copy-and-paste, transparency, foreground and background images, and easy file sharing.

WA particle system is a technique in game physics, motion graphics, and computer graphics that uses many minute sprites, 3D models, or other graphic objects to simulate certain kinds of "fuzzy" phenomena, which are otherwise very hard to reproduce with conventional rendering techniques – usually highly chaotic systems, natural phenomena, or processes caused by chemical reactions.

WPhyz is a public domain, 2.5D physics engine with built-in editor and DirectX graphics and sound. In contrast to most other real-time physics engines, it is vertex based and stochastic. Its integrator is based on a SIMD-enabled assembly version of the Mersenne Twister random number generator, instead of traditional LCP or iterative methods, allowing simulation of large numbers of micro objects with Brownian motion and macro effects such as object resonance and deformation.

This stand-alone application can be used in conjunction with other 3D programs to simulate fluids, water surfaces, fluid-solid interactions, rigid bodies, soft bodies and meshes. In 2008, Next Limit Technologies was awarded a Technical Achievement Award by the Academy of Motion Picture Arts and Sciences for their development of the RealFlow software and its contribution to the production of motion pictures. In 2015, Next Limit Technologies announced the release of RealFlow Core for Cinema 4D.

Like its predecessor, rFactor, it is designed to be modified and is used by professional racing teams for driver training and race car development. Much of its source code is derived from rFactor Pro which is also used by professional racers and most of the Formula One teams and NASCAR manufacturers.
WSimulation Open Framework Architecture (SOFA) is an open source framework primarily targeted at real-time physical simulation, with an emphasis on medical simulation. It is mostly intended for the research community to help develop newer algorithms, but can also be used as an efficient prototyping tool or as a physics engine.
WSoft-body dynamics is a field of computer graphics that focuses on visually realistic physical simulations of the motion and properties of deformable objects. The applications are mostly in video games and films. Unlike in simulation of rigid bodies, the shape of soft bodies can change, meaning that the relative distance of two points on the object is not fixed. While the relative distances of points are not fixed, the body is expected to retain its shape to some degree. The scope of soft body dynamics is quite broad, including simulation of soft organic materials such as muscle, fat, hair and vegetation, as well as other deformable materials such as clothing and fabric. Generally, these methods only provide visually plausible emulations rather than accurate scientific/engineering simulations, though there is some crossover with scientific methods, particularly in the case of finite element simulations. Several physics engines currently provide software for soft-body simulation.
