Geomagic Design

Powerful, Complete Motion Simulation

Dynamics for Geomagic Design is rigid body kinematics and dynamics simulation tool that lets you build and test functional virtual prototypes of your designs on the computer and simulate the full-motion behavior of those designs. It imports geometry, mass properties, and constraints from Geomagic Design and allows you to add motion specific entities to the model resulting in a functional operating prototype of your design. It simulates that prototype using advanced physics and mathematical techniques and presents the results of the simulation in various graphic and numeric formats. You can quickly determine how your design operates and determine if it meets your design objectives or if modifications are necessary.

Robust Simulation Modeling

Dynamics for Geomagic Design has a rich set of functional objects that are added to your CAD model to build a functional operating prototype. These objects include:


3D Collision

Collisions between parts are handled easily allowing the simulation of mechanisms like ratchets, clamps, grips, and others that rely on contact between two or more parts to operate. Contact forces and friction forces that occur at the time of contact are calculated and available for plotting.



Function Builder

Motors, actuators and forces can be driven by the Dynamics for Geomagic Design formula language, tabular data, or values in an Excel spreadsheet. This allows phenomena like motor start up and spin-down characteristics, variable speed actuators, and electro-mechanical controllers to be incorporated in the simulation model.



Dynamics for Geomagic Design contains a powerful formula language that allows simulation entity properties, instantaneous simulation values, and mathematical expressions to be combined into an expression that is evaluated during the simulation and which can be used to define physical values in the simulation. Formulas can also be used to generate values for display on probes. For example the formula:

0.5*Body[49].mass*mag(Body[49].v)*mag(Body[49].v)


when added to a probe will display a graph of the kinetic energy of Body[49]. The formula language can also be accessed using a function builder that allows equations to be assembled interactively. The function builder contain an integrated graphing capability so as a function is defined, its graph is displayed and updated.

Reporting

The Dynamics for Geomagic Design simulation engine calculates the displacement, velocity, and acceleration of each body in the motion model and reactions forces that act on each body as a result of its dynamic motion. This includes the motion and forces that result from any collisions between parts. Each of these quantities can be displayed on meters either in graph or digital format. The values can be accessed with the formula language or tabulated on an HTML report. Graphical vectors can be created that visually show the quantities calculated during the simulation. The vectors can change size and direction as the quantities they display change. Motors and actuators can report their force or power requirements to help you determine the proper sizing of these elements, and parasitic losses due to friction can be determined.

Animation and Keyframing

Sometimes you need to do an animation instead of a simulation. Dynamics for Geomagic Design provides an animation technique known as keyframing. With keyframing you can specify motions in ways that are not based on physics. For example, you can keyframe an assembly turning into an exploded view in 3D. Even cameras can be keyframed to create “movie-like” scenes that pan, zoom, and highlight product features. You can also combine physics-based, simulated movement with keyframed animation to create complex motion sequences.

Rendering

Dynamics for Geomagic Design includes a built-in rendering component. Multiple light types and sources, texture mapping, shadowing and other effects are available. Combined with the animation capabilities it can produce very realistic “movies” of a design as it operates. You can watch your design operate and see how the stresses induced by the operation effect individual parts. The rendered animations and images can be exported to formats that allow placement on web sites, in documents, and presentations.
