Installation

To install AstroGrav, double-click on AstroGrav.dmg to open the disk image, and then drag the AstroGrav folder onto the Applications folder alias.

Startup

To start up AstroGrav, just follow these instructions.

  1. To open your Applications folder, open a new Finder window, and click on Applications in the sidebar. Alternatively, double click on the Applications folder alias.
  2. Double-click on the AstroGrav folder to view its contents. It contains the AstroGrav application and four other items.
  3. To open AstroGrav, right click or control+click on the AstroGrav application and then select Open from the popup menu. [Double click probably won't work first time, but should work on subsequent occasions.]
  4. [Optional] Drag the AstroGrav application to the dock, so that it's easily accessible in future.

Note

If you have particularly demanding requirements together with a fast computer with more than 2GB RAM, you will probably benefit from reconfiguring AstroGrav to use more memory than it uses by default. This will enable you to do things that require large amounts of memory, such as the following.

  • Using several simulations at the same time.
  • Having a large number of windows open at the same time.
  • Having a large number of objects in a simulation.
  • Importing large numbers of asteroids into solar system simulations.

Increasing the amount of memory that AstroGrav uses does not significantly effect the speed at which simulations evolve. The information in the FAQs provides several useful techniques for speeding up simulations.

Increasing the amount of memory that AstroGrav uses is quite straightforward, and if you send an email request to Technical Support and Assistance, you will be sent the necessary instructions.
