Designing high quality, reliable products is always a prime motivation for a wide variety of Industries from home appliances to land vehicles. While it is possible to use physical testing to verify durability, it is most efficiently done by applying simulation methods integral to the development process.

Abstract
As focus on the world climate rises, so does the demand for ever more environmentally friendly technologies. The response from the automotive industry includes vehicles whose primary propulsion systems are not based upon fossil fuels, namely Full Electrical Vehicles (FEV). There is an opportunity to design and engineer new innovative FEV architectures, whilst minimising their mass in order to further reduce carbon emissions. This paper proposes an engineering process for optimising new FEV lightweight vehicle architecture based on a technique entitled topology optimisation, which extracts the idealised load paths for a given set of load cases. Subsequently shape and size optimisations are conducted in order to obtain detailed information of localised vehicle geometry such as individual BIW cross-sections. The research discusses each individual step of the overall process including successes, limitations and further engineering challenges and complications which will need to be resolved in order to automate the vehicle architecture design to include e.g. durability and (dynamic) crashworthiness performance.

HyperWorks Solvers
HW-10.1-SA1-206-HWsolvers and HW-10.0-SA1-206-HWsolvers were re-released last week to fix an incorrect label shown in the RADIOSS output header section, ALPHA-14516, when running a RADIOSS job after installing the above SA updates. This mislabel incidence does not impact the application functionality, you can continue using the software as it is. This issue has been fixed and you can download the new package and re-install it on top of the current installation if you wish.

The University of Stuttgart Formula Student Team, “GreenTeam”, Optimizes and
Develops Winning Electrical Formula Student Car with HyperWorks
„We use HyperWorks throughout the
entire development process of our car,
for concept design and optimization, from
meshing to solving and post-processing
and it has helped us to significantly reduce
the weight of our car, to make it better
and faster. In addition to the benefits we
gain from using HyperWorks as a software
tool it is also a great pleasure to work with
the Altair Engineering team. The support
they provide us with is outstanding
and from everything they do with us –
software, training, events, or support –
you can always tell that they are just as
enthusiastic about the Formula Student
projects as we are.”

“Did You Know” that AcuSolve requires a single topology and parent volume for each Simple BC, Element BC, Surface Output, etc. command? This becomes very important when using mixed-element meshes. For example, if you have an inlet surface that has trias and quads, this will get written as two separate Simple BC commands – one for the trias and one for the quads. So if you use a mass_flux, flow_rate, or average_velocity inflow type, you’ll get the defined value for the inlet set of trias and that same value for the inlet set of quads – effectively yielding a higher inflow than desired. You’ll also get a strange inlet profile – the computed profile for the trias and the computed profile for the quads.
There my be other Surfaces where this topological separation creates undesired effects as well.
There are two suggestions to handle this.
1. Split the mesh to all tets – so no more mixed-element boundaries. You can do this in HyperMesh or in AcuConsole (Edit > Mesh 2 Tets.)
2. If you really want to use a mixed-element mesh, then it’s better to use a velocity inflow type and define the constant velocity components, or use User Function to define the desired profile.

Coupling simulations from different domains is becoming increasingly important, considering the evolution of CAE toward multi-physics problems. As an example, utilizing residual stress/strain as well as thinning information from metal-forming simulation is gaining rapid acceptance in the structural CAE community. Most of the time, components of full-car crash models are defined independently from any residual stresses and strains, and thicknesses are considered as nominal, whereas a lot of these ones have been manufactured thru stamping or bending processes.
