ANSYS has many product specific interfaces that can individually be customized by the user. Two of which, are the Mechanical APDL and Workbench Mechanical interfaces. Customization possibilities within the Mechanical APDL interface has long been around; however the need to customize the Workbench interface is growing among customers as the demand for the use of this GUI increases. A large amount of customer interest has been focused around customizing the Workbench Mechanical interface. While many customization options are available, a focus on interacting with existing Mechanical features through scripting will be made. This presentation will provide examples of various types of customization that are possible within both the Mechanical APDL and Workbench Mechanical GUIs.
The presentation includes a benchmark study of different optimization methods that take advantage of an ultra-fast finite element analysis method based on space-time transformations. The novel algorithm accurately predicts the magnetic field, output torque including cogging and ripple, and core loss of a candidate machine design at any load conditions based on only a few magnetostatic calculations. When implemented with the powerful Maxwell 2-D scripting in combination with VBscripts and Matlab, a very large number of candidate designs can be studied in record time.
By combining the finite element method (FEM) and the integral equation (IE) solution within a single solver, engineers can realize a more efficient solution to large-scale electromagnetic problems.

Moving-bed biofilm processes, which sometimes incorporate high-surface-area plastic media within an aerated tank, have emerged as promising wastewater treatment technology capable of high-rate biological nutrient removal. For these processes, the aeration system plays two pivotal roles: supplying oxygen to bacteria and mixing the plastic media. This presentation discusses the optimization of mixing requirements within a clean water rectangular tank filled with moving-bed biofilm media by exploring the effects of various aeration grid configurations and airflow rates using CFD simulations.
The application of advanced composites to aerospace, automotive, wind turbine, marine and jet engine components presents some very unique challenges.

This session hosts a live demonstration of the latest domain decomposition features in HFSS. HFSS with HPC accelerates simulation and increases the capacity and fidelity of the most challenging simulations.
Proper thermal management of PCBs is important for achieving low failure rates and high power density. Excessive PCB temperatures can cause stress-related mechanical failures, electrical problems in active components, and excessive resistive losses in printed metal wiring. There are a number of challenges to rigorous thermal simulation: the complex pattern of metal traces can cause the effective thermal conductivity of a PCB layer to be anisotropic and difficult-to-predict; heat is generated in active components as well as through resistive losses of high-power nets; and the amount of resistive loss is dependent on temperature due its effect on copper conductivity. This study presents a methodology that addresses these challenges.
To modify impellers within solution preparation vessels, engineers at Lonza used design of experiments (DOE) for mapping current- and future-state mixing conditions. A CFD simulation model was developed and validated with mixing results. CFD and mixing models ensure replication of mixing conditions for retrospective and prospective process analysis, and they also can reduce process validation requirements.
Designing for durability can avoid costly repairs, legal liabilities and maintain product integrity. ANSYS nCode DesignLife enables product virtual testing before the initial prototype is built. The technology predicts time to failure for products that undergo repeated loadings. Learn how ANSYS nCode DesignLife can optimize your products for durability, resulting in significant cost reduction for design, manufacturing and maintenance.

Design examples of flex circuits, SiP, touch screens, and system level compliance will be among the designs highlighted.
The product purification process consists of a number of distinct steps. Most steps require temperatures to be colder than the ambient temperature. Currently, the temperature requirement is satisfied by conducting the entire operation under a cold room environment. The goal of this study is to examine the feasibility of operating purification columns under ambient environments without exceeding the specified temperature limits. CFD modeling is to simulate the heat transfer processes in the column.

Come see how SpaceClaim simplifies and prepares geometry for both structural and fluid analysis in a matter of minutes.
The proliferation of active medical implants has led to a shift in safety concerns related to MRI scans. Traditionally, MRI equipment manufacturers used electromagnetic-based design tools to properly tune and design new scanners. But today, implant manufacturers must submit proof that their implants will not cause improper heating of human tissue under MRI scanning conditions. This presentation demonstrates a simulation flow that makes it easy for non-electromagnetic experts to complete compliance simulations.
This session hosts a live demonstration of distributed solve (DSO). Learn how DSO accelerates design space exploration to enable innovative designs.
As building codes continue to raise standard, buildings with predominantly glazed facades require more efficient and innovative HVAC design. Due to the prevalence of floor-to-ceiling windows and skylights in these spaces, maintaining comfort in the occupied zone becomes challenging. The confluence of efficiency and occupant comfort necessitates an HVAC system that utilizes new or untested technologies. This presentation shows how a CFD simulation analyzed an active chilled-beam system that has supply inlets at a large distance from the conditioned space.
Poly-L-lactic acid (PLLA) is a bioabsorbable thermoplastic material increasingly used in biomedical applications, such as for local drug delivery, orthopedics and tissue engineering projects. In in-vivo conditions, PLLA exhibits a nonlinear viscoplastic response characterized by time-dependent effects, such as strain-rate sensitivity, creep and stress relaxation. This presentation shows how an advanced user-material model can be used in ANSYS to accurately capture these important behaviors.
