[edit] How to install VisIt

[edit] Installing on UNIX and Mac

  • visit-install syntax
  • picking a network configuration
  • picking a default bank

Using the installation wizard is pretty straightforward, just follow the instructions on each screen until done.

Here are a couple of screenshots of the Components page, showing how to remove some of the database readers to possibly improve startup performance.
