What is iMesh ?

iMesh is a Java applet, that is a computer program that runs within a web browser, without necessitating an installation. It is rather fast and efficient and is meant to be used rapidly as part the 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 formats.

IMPORTANT

There is a bug in the current version of iMesh: if one of the coordinates of your data points exceeds the range from -8000 to +8000, the triangulation will fail. This can be avoided by using appropriate units, for example working in meters instead of millimeters.

Available help

The following resources are available for help:

• A short explanation of the buttons of the iMesh user interface

• A hand-on tutorial for the iMesh applet STRONGLY RECOMMENDED!

• A detailed description of the iMesh input file format (if you want to create manually your input to iMesh

• An explanation on the use of consistent units in iMesh, and the preferred units:
  meter [m], MegaNewton [MN] and MegaPascal [MPa]

• A description of the iMesh neutral output format, that can be used to generate finite Element input files for programs not directly supported by iMesh (in development).
