ANSYS software system interfaces with knownCAD-systems, Unigraphics, CATIA, Pro / ENGINEER, SolidEdge, SolidWorks,Autodesk Inventor, and others.

About Ansys HFSS

HFSS(Three-dimensional modeling of electromagnetic fields) - a powerfulsoftware solution that calculates the multi-mode S-parameters andelectromagnetic fields in three-dimensional passive structures ofarbitrary shape. The transition from the program, who intend tostructure the methods of microwave circuit theory (to which the methodOliner, having in some cases, high enough for practical problems ofcalculation accuracy) to a program that performs a full calculation ofthree-dimensional electromagnetic fields, due primarily to the fact thatmany of the real device can not be decomposed into elements that are inthe library of models. This can be attributed even to the simplest caseanalysis of the smooth rotation of a multilayer microstrip line whenyou can not divide, where the microstrip line, and where the line issuspended from the substrate.
HFSS is used to solve the equations ofelectrodynamics, the finite element method (Finite Element Method, FEM),which includes adaptive generation and division of cells. Solutions forthe electromagnetic field, found from Maxwells equations to accuratelydetermine all the characteristics of a microwave device, with theemergence and transformation of some types of waves in the other lossesin the materials and the radiation, etc.
HFSS provides simulationcapabilities of antennas, power dividers, the circuits of switching,waveguide components, filters, microwave and three-dimensionalinhomogeneities, whose description is to create a drawing of thestructure (Fig. B-1), the exact specification of the material,identification of ports and the required characteristics. As a result ofthe calculation are the fields inside and outside the structures, aswell as multimode S-parametry.Rasschitannye S-parameters can be usedlater in the programs of analysis of linear and nonlinear schemes, inparticular, the program MicrowaveOffice, AnsoftDesigner or ADS.
