• Avoid turbulent behavior of liquid metal during filling.
• Retain impurities, foam and slag from the metal.
• To avoid sudden impact of metal in the cavity due to head height.

Altair OptiStruct – Viscoelastic Material
The behavior of Viscoelastic materials is intermediate between the idealized behavior of elastic solids and viscous liquids. The time domain Viscoelastic material in OptiStruct is represented by the generalized Maxwell model and is defined by a Prony series expansion.

Altair OptiStruct – Creep Material
Creep is the permanent time dependent deformation occurring in structures, can be defined using MATVP bulk card entry. It is based on power-law model and can be used in its ‘time hardening’ form or in the corresponding ‘strain hardening’ form.

Altair OptiStruct – Manufacturing Constraints Support for Multiple-Material Topology Optimization
All manufacturing constraints are supported for Multiple Materials Topology optimization (MMAT) from v2019.1.Different manufacturing constraints could be applied to different candidate materials in the same design domain. The original material defined by property will not be taken as candidate material by default. OptiStruct will error out if there is only one candidate material defined for the same design domain in MMAT.The element density result is available for all candidate materials in v2019.1.

Introducing Altair EDEM
Altair's acquisition of DEM Solutions allows customers to design and develop power machinery while simultaneously optimizing how this equipment processes and handles bulk materials. EDEM's Discrete Element Method tool interfaces with Altair's leading physics applications to extend companies ability to simulate complex products as systems-of-systems.

With EDEM, users will be able to simulate the interaction between materials such as pellets, tablets, powders, coal, soil, and rocks with machinery. Combining DEM with Altair's applications for model-based development, structural analysis, computational fluid dynamics, and multi-body dynamics gives users unparalleled insight into the performance of their complex products in use.

Altair Inspire Print3D Datasheet
Altair Inspire Print3D is an additive manufacturing (AM) product development and process simulation solution that enables teams to enhance part quality and minimize lead time and AM costs by reducing material usage, print time and post-processing. It provides a fast and accurate toolset for the design and process simulation of selective laser melting (SLM) parts.

Development of A new vehicle front sub-frame using Altair Inspire topology optimization
Presentation by Edan Lazerson, CAE Engineer, Plasan.


The Stormrider is a new vehicle which was designed from scratch and developed by Plasan. Altair Inspire was used for Topology optimization In order to find the ""best"" design for the vehicle front sub frame. The available volume (design space), 5 different load cases and target mass were specified and the optimization software calculated geometry to maximize stiffness. The optimization results were complex to manufacture with traditional technologies; the simulation and design teams collaborated on designing a manufacturable front sub frame assembly. The new design was simulated to ensure it will withstand all the required loads. The front sub frame was implemented and tested on the prototype vehicle. The optimized front sub frame proved mechanically sound, while satisfying the mass and geometrical requirements. The early stage optimization reduced the development time, by creating a valid geometry however, the topology to manufacturable design process is not trivial. In this presentation, we will present the mentioned development stages and compare the test results to the simulation predictions.
