Soft bodies are deformable and elastic objects, for example cloth, rubber or jelly. This solver provides a wide variety of features, great stability and accurate results. Users of previous versions will quickly discover that there are absolutely new parameters available. Another new feature is that soft bodies can now keep the deformation they experience (“Plasticity”). With this approach it is possible to simulate bending metal, as can be observed after car crashes, for example. These sophisticated possibilities open up a whole new world of soft body dynamics and, of course, the new solver can interact with particles, rigid bodies and waves.
Density
A dynamic object always needs a certain amount of mass to become influenced by forces. In RealFlow, mass is always given in kilograms and the initial value is calculated automatically. Actually, the “Density” parameter from the “Soft body” panel has exactly the same mode of operation and functionality as its counterpart in “Rigid body”. Density is defined as mass per volume unit [kg/m3].
