TriD

TriD is the integrated solver for the smart analysis of electromagnetic response of  complicated structures placed in free space or above a ground plane. Metallic structures consisting of arbitrary shape wires and surfaces (both open and closed) are handled in TriD. The program allows finite conductivity of wire segments by specifying their resistance, inductance and capacitance. Any linear time invariant passive circuit can be incorporated into the calculation with a unique SPICE link. Different types of excitation sources are available in TriD including incident plane wave, voltage source over a wire segment, current sources, impressed currents, electric and magnetic dipoles as well as any arbitrary combination of sources.

The core of TriD is based on the Method of Moments (MoM) to numerically solve the Electric Field Integral Equations (EFIE) for the induced electric currents on wires and surfaces. Triangular basis functions for the surface and segment currents and special basis functions for the junction currents have been developed into TriD to calculate the induced electric currents on the whole structure. Different extremely fast solvers developed at EMCoS (out-of-core version, parallel cluster version), are used in TriD for solving the resulting systems of linear equations to obtain the coefficients of the current expansion. The out-of-core and parallel solvers allow the calculation of very large problems. With a well equipped modern PC solution of problems with 40.000 unknowns and more can be done TriD chooses automatically the best solver without user interaction. With the inverted equation system both the current and charge distributions on the whole structure are available, and the desired characteristics of the structure are calculated both in near and far field. Special calculation features aiding antenna calculations are implemented.

A number of user-orientated original visualization tools such as the TriD Task Editor and a surface/charges 3D viewer have been specially developed for TriD. TriD is fully compatible to the EMC Studio product line and can be very easy used within this environment. A number of additional tools for mesh generation like ReMesh and result processing like Graph Studio can be used to allow to solve even extremely complicated calculation problems.
