HiPhi计算任意三维系统中的静电场。该程序可以生成电介质或导电溶液。在电介质溶液中，溶液空间的区域可以代表电极、电介质和空间电荷密度。在导电溶液中，这些区域对应于电极或电阻性介质。你可以在一个解决方案中包括多达250种材料类型。HiPhi有几个功能：

• 使用有限元技术对共形六边形网格进行高精度计算

• 通过结构化网格实现不凡的计算速度，对具有FORTRAN95编码的多核Windows PC进行了优化

• 大网格容量的动态内存分配（标准PC上20-5000万个元素）

• 根据数学表达式将电位、介电常数、电导率和/或空间电荷密度的连续空间变化分配给区域的技术

HiPhi软件包包括两个程序：

• hiphi.exe—在窗口中以交互式方式或在批处理文件控制下自动生成静电解决方案

• phiview.exe—符合要求的后处理器从HiPhi解决方案文件生成绘图并计算场量

MetaMesh是AMaze通用共形网格生成器，用于准确输入几何文件。

【英文介绍】

HiPhi offers unparalleled computational power, speed and accuracy for 3D electrostatics at a moderate price. The program handles user-specified geometries that may contain regions of electrodes, dielectrics, space-charge and resistive materials. The self-contained package includes Geometer (interactive environment for building 3D geometries), MetaMesh (automatic conformal mesh generator) and PhiView (postprocessor for plots and interactive analyses). The program features high computational speed — a 200,000-node calculation takes less than 1 minute on a typical personal computer. HiPhi has application to areas such as high-voltage engineering, circuit component design, electro-optical and vacuum microelectronic devices, electroplating and electrostatic equipment.

Features

• Specify continuous spatial variations material properties from mathematical functions.

• Advanced solution techniques to resolve microscopic details in large structures.

• Extensive array of 2D and 3D plotting options.

• Interactive point-and-click analysis of solutions.

• Option to run HiPhi and PhiView in batch mode for extended calculations。

• Automatic surface integrals of normal fields to calculate mutual capacitances and electrode currents.

•  Interactive line scans and plots with digital oscilloscope features.

HiPhi calculates electrostatic fields in arbitrary three-dimensional systems. The program gen-erates either dielectric or conductive solutions. In dielectric solutions, regions in the solution-space may represent electrodes, dielectrics and space-charge density. In conductive solutions, the regions correspond to electrodes or resistive media. You may include up to 250 materialtypes in a solution. HiPhihas several advanced capabilities:

• High accuracy calculations using finite-element techniqueson conformal hexahedron meshes.

• Unmatched computation speed through unique structured meshes, optimized for multi-core Windows PCs with full FORTRAN95 coding.

• Dynamic memory allocation for large mesh capacity (20-50 million elements on a standard PC).

• Advanced techniques to assign continuous spatial variations of potential, dielectric con-stant, conductivity and/or space-charge density to regions from mathematical expressions.
