(continued...) An improved solver is used in the 2003 version and user enhancements include the opportunity to interrupt a lengthy kinematic solution.
Definition of 3D contact between multiple parts has been improved with contact containers and simulation of vibration isolating mounts and non rigid joints is possible with isotropic bushings that have both spring and damping characteristics.
Visualisation is improved with springs rendered in wireframe or shaded and result vectors with size proportional to their value.
As always, Motion allows plots of all parameters to be dynamically graphed as the mechanism simulation runs.
The final element in the analysis arsenal is computational flow dynamics.
Traditionally a highly complex exercise exclusively on UNIX and undertaken by specialists, Nika pioneered the opportunity for CFD to be integrated into the mainstream design process.
FloWorks was incorporated into the SRAC product line to replace their own Cosmos/Flow product and hence now appears in the SolidWorks line-up as CosmosFloWorks.
Whilst maintaining the focus on ease of use, significant new functionality has been added in 2003.
Non-newtonian liquids can be modelled based on predefined viscosity models enabling real liquids such as tooth paste or blood to be simulated.
Heat transfer by radiation from and / or between solids can be considered and automatic convergence control aims to ensure stable solver convergence.
Visibility of goals also aids understanding of convergence behaviour.
The Cosmos suite of analysis tools makes significant testing of virtual prototypes possible.
This can greatly increase the value of 3D CAD models by reducing the number of time consuming iterations of physical prototypes and enabling the exploration of a wider number of design alternatives.
As always care must be taken in analysing results in this virtual world, particularly as increasing ease of use make it possible for any designer or engineer to generate a credible looking study.
With careful consideration of the problem and judicious use of confirmatory calculations or empirical testing, analysis tools will enable design issues to be highlighted and solutions optimised much earlier and more cost effectively.
