iMesh is a Java applet, that is a computer program that runs within a web browser, without requiring an installation. It is rather fast and efficient, and is meant to be used rapidly as part of teaching and exercise activities.
The purpose of the iMesh program is to model two-dimensional bodies and to create a Finite Element Mesh suitable for input a Finite Element program. The companion applet iConc is the primary target, but iMesh can also produce input files for other format (currently ANSYS). The models that iMesh can create are plane and, in the current version, loaded by point loads acting in the plane of the element. Figure 1 shows a typical example of the type of structures that can be worked on with iMesh: it has a rather complex geometry, with supports at two different levels, a non-rectangular opening and two applied loads. With iMesh, as you will soon discover, it is rather simple to create a model of that structure that can be then calculated using the iConc applet.
