Ansys has announced the release of HFSS 12.0 software for 3D full-wave electromagnetic field simulation.

The product, part of the Ansoft suite, helps engineers design, simulate and validate the behaviour of complex, high-performance radio frequency (RF), microwave and millimeter-wave devices in wireless communication and defence systems.

A high-performance computing (HPC) enhancement, domain decomposition, allows engineers to simulate and design at a scale and speed never before possible, according to the company.

The software includes key updates in mesh generation, solver technologies and enhancements to the user interface and the modeller.

A faster, more robust meshing algorithm generates higher-quality, more efficient tetrahedral meshes.

Enhancements include mixed-element orders, curvilinear elements, adjoint derivative computation and additional modeller capabilities such as sheet wrapping and imprinting.

These advances in HFSS 12.0 enable electrical engineers to expand their solution capability, exploit HPC hardware and fully integrate electromagnetics analysis into their Simulation Driven Product Development processes.

The domain decomposition technology allows efficient and highly-scalable parallelised simulations across multiple computer cores, including networked cores.

Curvilinear elements and mixed element orders allow for higher accuracy and more efficient distribution of computational resources.

Curvilinear elements model the fields exactly on curved surfaces and provide higher accuracy, even with a coarser mesh discretisation.

Mixed element orders allows for an automated and judicious localised application of element order.

Smaller features are solved more efficiently by lower-order elements, while large, homogenous regions benefit from higher-order elements, all element orders being automatically and appropriately mixed in one mesh.

Molex was among the organisations that participated in beta testing the release.

Adjoint derivative computation provides an efficient and accurate procedure to evaluate the derivatives of S-parameters with respect to geometric and material-model parameter variations.

This technique provides sensitivity information for use in device tuning, tolerance evaluation and optimisation.

These derivatives are employed to speed up the sequential nonlinear programming (SNLP) optimiser included with the Optimetrics add-on programme.
