You can quickly grips, and others that rely on contact determine how your design operates between two or more parts to and determine if it meets your design operate. Contact forces and friction objectives or if modifications are forces that occur at the time of necessary. All on the computer, all contact are calculated and available without costly and time-consuming for plotting, query or use by SimWise physical prototypes. FEA.

Powerful Formula Language Programmability and Function Builder SimWise contains a very rich automation interface which allows it to be SimWise contains a powerful formula language that allows simulation entity both interfaced with and controlled by other applications. Programming properties, instantaneous simulation values, and mathematical expressions languages such as C++, C#, Visual Basic, Java, and even vbScript can be to be combined into an expression that is evaluated during the simulation used to customize SimWise. You can automate the integration of SimWise and which can be used to define physical values in the simulation. into your proprietary processes and your proprietary calculations can be Formulas can also be used to generate values for display on meters. For used from within the SimWise environment. example the formula:

0.5*Body[49].mass*mag(Body[49].v)*mag(Body[49].v) When added to a meter 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 The function builder allows complex functions to be defined graphically displayed and updated.

Photorealistic rendering and animation Annotation and Mark-up SimWise uses high quality, high performance rendering technology from Annotations in the form of text, call-outs, and distance and radial dimensions Lightworks. Multiple light types and sources, texture mapping, shadowing can be added to the simulation model. The distance dimensions are active in and other effects are available. Combined with the SimWise animation that they update if the model is moved or animated. SimWise also provides capabilities it can produce very realistic “movies” of a design as it operates. a distance dimension that shows the points of closest approach and the Stress contour results can also be incorporated in the animations. You minimum distance between two bodies. This dimension also updates as the can watch your design operate and see how the stresses induced by the bodies move. operation effect individual parts. The rendered animations and images can be exported to formats that allow placement on web sites, in documents, and presentations. Cameras that move in space or which can be attached to parts are supported. This allows you to produce “fly-through” type animations or view the design operating from a “birds-eye” view as if you were sitting on one of the parts. SimWise also 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 script a corporate logo flying through the air, or a parts-exploding automobile engine to show how it is assembled. 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. Texture mapping, reflections, and shadows can all be used in animations SimWise Plant model integrates with Simulink SimWise FEA Mechanical Stress Analysis
