You must install Java before you can use Energy3D. For security reasons, it is strongly recommended that you download the latest version of Java from java.com. Make sure that you UNCHECK any annoying software (such as the Ask.com tool bar or app) bundled with the Java installer to avoid getting unwanted software along with Java.
Energy3D is available for free download in two ways: Web Installer and Zip Installer.
The Web Installer uses the Java Web Start technology to automatically download and install Energy3D to your computer and is the recommended way to install Energy3D. On Windows and Linux, you just need to click the Web Installer link. On Mac OS X, clicking the Web Installer link will download a tiny zip file. Unzip it and then double-click on the energy3d.jnlp file contained in it.
Only when you run into problems with the Web Installer should you use the Zip Installer. After unzipping the downloaded file, you can launch Energy3D by double-clicking the energy3d.jar file. Mac OS X users: When you are using Energy3D in this way and you are using version 10.9 or higher, Mac OS X requires all apps to be signed with an Apple Developer ID. Unfortunately, the energy3d.jar is not signed. To work around "App can't be opened because it is from an unidentified developer" alert message from the Gatekeeper, you should do the following:
- Right-click (or control-click) the energy3d.jar file and choose "Open".
- Click the "Open" button at the next dialog to launch Energy3D.
