CREATING A GEOMETRY MODEL IN HOBBIES

4.0 SUMMARY

A Higher Order Basis Based Integral Equation Solver (HOBBIES) project consists of a geometry model, the electrical properties of the electromagnetic materials associated with that model, and the parametric settings of the solution. As is well known, the geometry modeling is very important since it describes the object that is essential in an electromagnetic simulation.

In general, HOBBIES provides two ways to create a model of the electromagnetic structure:

• Using the HOBBIESStructure menu to create a simple shaped model
• Using the Geometry menu to create an arbitrarily shaped model

Users can draw arbitrary one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D) objects using either of the procedures, as discussed in detail in this chapter. HOBBIES can also import geometric models of structures from other software, such as AutoCAD, Rhinoceros, and Pro/E, as described in Section 3.5.2 of Chapter 3.

To draw a model efficiently, one can perform various operations and manipulations with previously created objects (points, wires, surfaces, etc.). The operations include moving a point, dividing lines/surfaces, collapsing, Boolean operations, and so on. The manipulations include translation, rotation, mirroring, scale, offset, sweep, and align. These operations and manipulations of the model are discussed at the end of this ...
