Dimensional Constraint Manager (DCM) components for variational modeling is an application of the 3D DCM in direct 3D variational control of the shape of CAD models. Until now, the 3D DCM has focused on assembly positioning and mechanism simulation applications, in which each part is treated as a rigid object. Direct variational part modeling is a topical new area of functionality, enabling CAD systems to reduce their reliance on older, less powerful, history-based techniques.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
