SETTING UP A HOBBIES SOLUTION AND RUNNING A SIMULATION

6.0 SUMMARY

Once the geometry modeling is completed, the user can define a Higher Order Basis Based Integral Equation Solver (HOBBIES) project, create a mesh, and run simulations. The HOBBIES solution settings include specifying the operation mode, units, frequency, and so on. The operation mode determines whether HOBBIES solves either the radiation from an antenna or the scattering from an object excited by a plane wave. The unit option will define the units of frequency, coordinate, radius, voltage, and field. It also provides functions to convert the unit or the value of a variable into different units.

Assigning domains is an essential step in a HOBBIES project. In this chapter, the user will learn how to define domains and how to assign a domain to wires and quadrilateral surfaces. For complicated models involving multilayer structures, the user can make use of Layers to ease the job.

HOBBIES is capable of modeling both concentrated and distributed loading. The concentrated loading can model lumped elements such as resistors, inductors, capacitors, or their combinations. The latter is useful for modeling loading over a wire or a quadrilateral surface to simulate a coated structure, for example. Both types of loading are explained in detail later.

Two additional settings that may be involved in a HOBBIES solution are symmetry and edging. Symmetry properties can be used to speed up the analysis only if both the geometry ...
