R&D teams must accurately predict how complex products will behave in a real-world environment. Only the ANSYS suite comprehensively captures the interaction of multiple physics — structural, fluid dynamics, electromechanics and systems interactions — with deep physics and from within a single simulation system.
A new ANSYS Fluent® cosimulation link with ANSYS Simplorer® allows engineers to analyze battery systems in Simplorer without neglecting nonlinear behavior of the fluid system. The cosimulation delivers high-accuracy results of multidomain system simulation using a fully integrated set of tools.
ANSYS 14.0 also introduces two-way electromagnetic coupling with stress analysis and the ability to re-simulate the electromagnetic field distribution on the deformed geometry. Applications include electrical machine, magnetic actuator and electric transformer designs in the automotive, aerospace, and power industries, for which accuracy of localized part deformations is important.
The successful design of many industrial processes depends on accurately predicting the dynamics of, and interaction between, different phases (gas, liquid, solid particles). Because of continuous progress in the area of multiphase modeling, ANSYS fluid dynamics capabilities at 14.0 widen the range of multiphase applications that can be simulated accurately, efficiently and robustly.
Applications that must consider complex nonlinear phenomena — such as biomedical devices, hot rolled steel, acoustics and brake squeal — can benefit from the suite’s advanced models. For example, biomedical application developers access enhanced material formulations such as the Holzapfel model to capture behavior of fiber-reinforced tissue or shape-memory alloys for stent modeling. Moisture diffusion has been implemented in thermal, structural and coupled simulations for electronic components.
For enhanced insight, ANSYS 14.0 features a comprehensive suite of solver and HPC advancements across the entire range of physics. Smart solver management enhancements — including architecture-aware partitioning — evenly size and efficiently distribute jobs to available compute processors. “Petrobras relies on ANSYS software for its superior parallel scalability, together with advanced multiphase models and dynamic meshing,” said Carlos Alberto Capela Moraes, technical consultant at CENPES (Petrobras Research and Development Center). “New enhancements such as architecture-aware partitioning and improved scalability will allow us to consider even more detailed, accurate and complete simulations than ever before — yielding the kind of understanding that is essential to reproducing critical scenarios and complex operations of upstream processing systems in the oil industry.”
GPU advancements are being leveraged to produce increased hardware performance. With ANSYS Mechanical 14.0, users can take advantage of the latest generation of GPU boards as well as minimize the amount of I/O required for post-processing operations. ANSYS is committed to staying synchronized with the latest computing technologies.
In a compressor or turbine, accurately capturing the transient interaction between rotating and stationary blades is complicated by the different blade count (or pitch) between different stage rows. This pitch change often means that a time-accurate simulation requires modeling the full wheel, a full 360 degrees of geometry — a transient simulation that is sometimes computationally prohibitive. Users can dramatically reduce computation requirements, in terms of time and memory, with the new advanced transient blade row methods in ANSYS CFD™ 14.0. Only a few blade passages are required for simulation, yet results are highly accurate predictions of transient interactions.
In the antenna design field, an important research topic is analysis of finite-sized antenna arrays, which can provide beam-steering capability. Due to the structures’ large size, rigorous analysis with full-wave 3-D simulators has been a challenge. An accepted method is to solve a single element of the array with a linked boundary condition, extracting performance of this single element effectively embedded in an infinite array. Because the method neglects edge effects from the true, finite size of an array, the results are approximations of far-field patterns and element-to-element coupling factors. The new finite array capability in ANSYS HFSS 14.0™, built upon the proven ANSYS domain decomposition and adaptive meshing technologies, models the finite array explicitly. The time- and memory-efficient HPC technique properly predicts the array’s behavior including finite-size edge effects.
