Additive manufacturing makes designing a lattice structure for a bracket possible. However, does it have a chance of success? Simulation can tell you.
Traditional prototype techniques take weeks and cost a considerable amount of a product development budget.
It’s true that additive manufacturing has reduced the time and cost to build prototypes. However, the near-instant simulation capabilities of ANSYS Discovery Live can speed up prototyping labs even more.
“Traditional simulation tools are hard to use, take a long time to produce results and are too expensive to be used on a regular basis,” says Tejas Rao, manager of ANSYS’ Discovery Live Technical Team.
“Discovery Live, however, offers instantaneous real-time simulation in an extremely easy-to-use multiphysics interface,” Rao adds. “It also includes integrated geometry manipulation. This means you can do simulation on your own in seconds.”
HUD informs drivers of their speed, the speed limit, next turn and more — without forcing them to move their eyes off the road.
Any fan of Iron Man knows the power of an effective head-up display (HUD). But you don’t need to be fighting Thanos to benefit from a HUD.
In fact, HUDs can become a significant enabler of advanced driver assistance systems (ADAS) in the automotive industry.
An effective HUD can inform a driver without forcing them to move their eyes off the road. It can show:
The road’s speed limit.
The next turn.
For engineers, the challenge is to design a display that doesn’t force the driver to change focus. As a result, the information must remain legible under all road conditions. Simulation can help engineers design HUDs for any condition. Continue reading →
Parameter studies in Discovery Live automates design point creation. The geometry and simulations are then automatically generated in real-time.
Real-time design analysis in ANSYS Discovery Live is now more automated. Previously, you needed to manually change each parameter to see a new simulation result.
When you had multiple parameters to adjust or were curious about all possible permutations, the process of manually iterating through the parameters could be time-prohibitive.
This is where Discovery Live’s parameter study feature comes into play. It allows you to rapidly explore numerous design possibilities by automatically cycling though geometric or simulation parameters. Continue reading →
Engineers are under pressure to optimize designs during ever-shrinking development cycles. In response, computer-aided engineering (CAE) tools — like the latest enhancements in the ANSYS 19.2 release — now facilitate faster and easier-to-use workflows.
New ANSYS Fluent Task-based Workflow with Mosaic-enabled Meshing
A Mosaic mesh of an F1 wing connects hexahedral elements in the bulk and isotropic elements in the boundary, using polyhedral elements.
Engineers using ANSYS Fluent can now create more accurate computational fluid dynamics (CFD) simulations.
Fluent’s single-window, task-based workflow for watertight geometries dramatically reduces the time to set up and run CFD simulations.
This new workflow incorporates best practices to help prevent engineers from second-guessing themselves as they set up complex CFD models. Continue reading →
Simulation shows how the additive manufacturing process distorted a bike stem after it was removed from its supports.
Engineers put a lot of time into designing parts to a specific tolerance. Unfortunately, metal additive manufacturing (AM) causes thermal stresses that can significantly deform these parts.
If the part warps — even a little — it could affect performance and how it fits into an assembly.
To predict and compensate for part deformations, engineers can use ANSYS Additive Print. The tool uses these predictions to ensures the print deforms into the part the engineer intended. Continue reading →
Traditionally, CFD experts and novices won’t be happy working with a hard-to-mesh geometry like this. However, Mosaic technology makes building this mesh much easier. (Courtesy of Centre for Sports Engineering Research, Sheffield Hallam University)
Mesh creation is one of the biggest reasons engineers have a hard time setting up a computational fluid dynamics (CFD) simulation.
Even CFD experts can have a hard time building a fast and accurate mesh from complex geometries and flow regimes.
The trick is that engineers need accuracy near the thin boundary layers, which requires a very tight mesh.
However, this tight mesh slows down the processing of the fluid’s bulk without adding any accuracy.
The solution is to have multiple meshes — with different densities and element types — at different regions of the geometry. This would give you meshes that are accurate at the boundary and fast in the bulk. Continue reading →
Engineers designing ADAS and autonomous cars can consolidate functional and safety management software by interfacing medini analyze to Jama.
Market demands are directing the automotive industry toward advanced driver-assistance systems (ADAS) and autonomous cars. Naturally, ADAS and autonomous systems add complexity to automotive products. This complexity breeds vulnerabilities that could plague safety management engineers.
These engineers must ensure the functional safety of their products to reduce liability and the risk to customers. Let’s face it, one class-action lawsuit could lead to bankruptcy.
Industry standards state that in order to ensure functional safety you must trace safety requirements to specific product properties. Unfortunately, tracing these links can be complex when your safety requirement software doesn’t talk to your requirements management software.
