This contribution to heuristic geometry proves the efficiency of the new generation of interactive tools for drawing in plane geometry in processes of theorem‐finding. The background of such processes should be seen in the general skills and abilities to be acquired by the pupils. The paper ...

As a simple example, consider an infinite array of radiating rectangular apertures in a ground plane. The figure below depicts a simple HFSS model for the unit cell of the infinite array. The model consists of two boxes. The lower box represents the feeding waveguide and the upper box is th...
This tutorial steps through the process of solving a 2D flow for the Lid Driven Cavity (LDC) example using physics-informed neural networks (PINNs) from NVIDIA’s Modulus Sym. In this tutorial, you will learn how to: generate a 2D geometry using Modulus Sym’ geometry module; set up the ...
Let's start by adding a plane:Go to the back view. Place the 3D Cursor near the middle of the headrest. Bring up the Add menu and choose Mesh | Plane. Open the Adjust Last Operation panel. Set Size to 0.22 m. Set Align to View. Set Location X to 0. Rename the new object Rear...

A circle is, a set of points equal distrance (radius) from a fixed point (center point) on a plane. Now that we have a set definition for a circle, let's quickly define the variables involved in the formulas of a circle. Area of a Circle (variable: A) is the area within the ci...
To represent flat surfaces, Unity includes the Plane and Quad primitive GameObjects that you can instantiate in your Scenes. However, it is useful to understand how to use a script to construct a quadrilateral mesh yourself. This is essential for procedu
A simple coil geometry is the Archimedean spiral. Its windings are in one plane, and they all have the same distance. We define the geometry of the coil by storing its properties in a struct. We call it arch, for Archimedean spiral. ...
A combinatorial class is defined by writing a grammar specification that describes it. In this way, an extensive collection of different classes may be defined. For example, the system applies to all regular and context-free grammars, grammars to define binary trees, plane general trees, necklaces...
