　　美國 ANSYS 推出了三維電磁仿真軟件 HFSS 的最新版本 HFSS 12。新版本在網格生成丶求解丶建模等方面的功能及性能有所改善。

　　例如，在網格生成方面，改進了四面體的網格生成。在求解方面，新版本配備了將處理高效分配給多核（包含網絡中分布的處理器）的區域分散功能。如果內核數量為8，則處理速度為單內核的8.8倍，需要的內存容量可以減少33％。

　　在建模方面，發布資料介紹了三點改進：即 mixed element order（不同次數的元素同時存在）丶curvilinear element（曲線元素）丶adjoint derivative computation（伴隨導函數運算）。其中，mixed element order能夠使不同次數的元素存在於同一網格中，以提高處理效率。一般來說，小區域使用低次元素求解較佳，較大且均勻的區域適合使用高次元素。而此次的mixed element order能夠對一個網格的多個元素，分別分配最佳次數的元素。

　　curvilinear element面向的是曲面建模，能夠提高網格粗生成的精度。而adjoint derivative computation能夠提供在場所及材料參數發生變化時高效評估S參數導函數的步驟。借助以上改進，可見元器件外邊緣，以提高優化處理的效率。

3D Full-wave Electromagnetic Field Simulation
HFSS is the industry-standard simulation tool for 3D full-wave electromagnetic field simulation. HFSS provides E- and H-fields, currents, S-parameters and near and far radiated field results. Intrinsic to the success of HFSS as an engineering design tool is its automated solution process where users are only required to specify geometry, material properties and the desired output. From here HFSS will automatically generate an appropriate, efficient and accurate mesh for solving the problem using the proven finite element method. With HFSS the physics defines the mesh, not the mesh defining the physics. Engineers rely on the accuracy, capacity, and performance of HFSS to design high-speed components including on-chip embedded passives, IC packages, PCB interconnects, and high-frequency components such as antennas, RF/microwave components, and biomedical devices.

The power of HFSS comes from many Ansoft pioneered research and development innovations. These breakthroughs have made HFSS the most widely used software for solving 3D full-wave electromagnetic field simulations.

Tangential vector basis functions enabled the highly accurate finite element method for electromagnetic field solution
Transfinite element method for fast and accurate multi-mode S-parameter extractions
Automatic mesh generation and adaptive refinement for reliable, repeatable and efficient results

New features in HFSS 12.0 software include:

New, robust TAU meshing technology
Domain decomposition solver technology
Curvilinear elements
Mixed element orders
Adjoint derivative computation
Update to ACIS R19.2
Improved link with ANSYS DesignXplorer software
