OptiStruct - Equivalent Plastic Strain Response for Optimization
Equivalent plastic strain can be used as an internal response when a nonlinear response optimization is run using the equivalent static load method. This is made possible through the use of an approximated correlation between linear strain and plastic strain, which are calculated in the inner and outer loops respectively, of the ESL method.

OptiStruct - Neuber Optimization Response in Nonlinear Subcase
Neuber Stress and Neuber Strain sensitivities are supported for optimization in small displacement NLSTAT. It was already supported for optimization in FASTCONT analysis. It is supported only for small displacement analysis, it is not supported for large displacement. Once Neuber response is defined, the material will be treated as linear and MATS1 props are used only for Neuber correction. It is supported for solids as well as shells. It is supported for all optimization types except topology & freesize optimization.

Predicting Multipacting for RF Design Optimization: Field Strength Measurements in a Coaxial Waveguide
Tech-X presents a highly efficient method of predicting multipacting for RF design optimization with the FDTD PIC code VSim. Multipaction is a commonly encountered problem RF engineers face, that causes significant damage to RF structures, in which there are very often no analytical solutions. Therefore, often the only way to predict multipacting is by using numerical solvers.

Both antennas and leaky feeder cables can be deployed in the 3D environment of the station/tunnel scenario including the train.
Improving Electric Vehicle Range with Advanced Losses Computation Considering PWM Across a Full Duty Cycle
Introducing electric traction in automotive brings new challenges for the design of electric machines. Nowadays designers have to consider increasing constraints like efficiency, temperature, weight, compactness, cost but also stricter regulations, while reducing time to market. Fortunatly, Altair proposes disruptive methodologies to make relevant choices in the early stage of the design, based on numerical simulation and optimization techniques.
Once the machine has been selected and designed in Altair FluxTM this webinar covers how an electric motor design's performance is evaluated and maximized considering its global efficiency along the whole driving cycle.
The next design challenge is to get an accurate estimation of the losses, which becomes more and more strategic in the design process in order to accelerated speed to market with balanced design and confidence. This estimation is also a key issue of thermal design. Therefore, the study of losses (in particular non-conventional losses) is crucial. Two methods are proposed to take the current wave form into account: by using an equivalent circuit model in Altair ActivateTM system modelling software, or by representing the PWM in Flux circuit context.
