Those technologies are:
Moving reference frame
Simplifies the otherwise transient problem of the relative motion of objects into an efficient steady state approximation, reducing run times by orders of magnitude in doing so. When used appropriately the results closely approximate those of far more computationally expensive calculations.
Rigid body motion (sliding mesh):
Allows parts to rotate and/or translate and with respect to each other, yielding time accurate flow data that includes the effects of transient interactions between components.
Allows for more complicated arbitrary relative motion by morphing the nodes of the mesh. Mesh morphing can be used to model scenarios where components deform and change shape, and is the basis for Fluid Structure Interaction (FSI) simulations.
Overset (Chimera) meshing allows bodies to move freely throughout the computational domain without being artificially constrained by the mesh. Separate overlapping meshes are used, a background mesh, and a body fitted mesh around the geometry of interest. The body and fitted mesh are then able to move freely without the need to remesh, and data is interpolated between the two meshes.
Dynamic fluid body interaction (DFBI)
Allows the modelling of motion of a body resulting from the forces and moments on it (both from the fluid and other external forces). It includes at its core a Six Degree of Freedom (6DOF) solver which is used in conjunction with other motion methods such as the mesh morphing and overset methods to allow bodies to move in response to the forces on them. The DFBI model also includes the ability to model external forces from connections such as springs or catenaries, or forces due to contact to prevent DFBI objects passing through adjacent boundaries. There are also a number of option for modeling reduced degrees of freedom for marine tow tank tests such as Four-DOF Maneuvering Motion, General Planar Motion, Planar Motion Mechanism, and Rotating Arm tests.
These models gives the users of STAR-CCM+ the power to model unlimited scenarios involving motion with ease.
