MELTS Applet

small logo

The MELTS Applet should display momentarily in its own popup window.

Please be patient. Loading the applet and constructing the GUI may take a while. If you close the applet window and want to run the applet again, just reload this page in your browser.

What does this applet do?

This applet accesses the MELTS CORBA server at OFM Research Inc. It allows the user to perform simulations of crystallization and assimilation in magmatic systems under various evolution scenarios, such as adiabatic decompression melting, fractional crystallization, etc. This applet is an alpha release that lacks certain critical functionality. At present only the Ghiorso and Sack (1995) model is implemented. A complete beta version should be available by early Spring of 2008. This version will include local I/O, assimilation and the model of Ghiorso et al.( 2002).

A fully functional standalone version of MELTS for Linux and Mac OS X systems may be downloaded from the MELTS web site. A deprecated MELTS applet may also be found at that location.

Source code and documentation

Documentation on the use of the applet is not yet completed. However, the interface is designed to emulate the standalone version of MELTS for Linux and Mac OS X systems. Documentation for the standalone version is available at the MELTS web site. Software for this client may be downloaded from the software page.

The applet will not display! What is wrong?

The MELTS applet is written in Java 1.4.2 and utilizes the Swing widget set for its graphical user interface. For the applet to function in a web browser, the browser must have a Java run-time environment (JRE) installed that supports these features.

This applet is known to work on Mac OS X operating systems (vr. 10.4, Tiger) with the Safari (vr. 2.0.3) browser and with the Mozilla FireFox browser (vr. 1.5). It will not function with the Internet Explorer (IE) browser (vr. 1.5.2) or with the Netscape browser (vr. 7.2) under Mac OS X. If you are using Internet Explorer, note that Microsoft recommends switching to Safari as they no longer support IE on the Macintosh platform.

Under Windows and Linux, you will have to update the JRE for Internet Explorer and perhaps for Netscape and Mozilla. There is an excellent web page that provides instructions on how to do this and also a means of testing which version of the JRE is installed in your browser at JavaTester.org.
