Operating Systems

Windows

Simunto Via runs on Windows 7 (SP 1) or newer, including Windows 8 and Windows 10.

macOS

Via runs on OS X 10.11 (El Capitan), macOS 10.12 (Sierra) or later.

Linux

Via should run on most modern x64 Linux distributions. It can be run on other distributions as well if OpenJDK / Java 11 is provided.

Memory

To run Via, make sure you have enough RAM. Small scenarios can usually be visualized with less than 1 GB of RAM. Car-only scenarios with around 0.5 million agents can be run with around 3 GB of RAM, while multi-modal scenarios with around 1 million agents require about 6 GB of RAM.

Change the RAM limit

Java applications need to have a limit set, how much memory they can use (using the -Xmx argument). To change this limit (e.g. to load bigger scenarios), proceed as follows:

  • On Windows: open the file via64.ini in a text editor and change the corresponding values.
  • On macOS: right-click on the Via application, and choose Show Package Contents. A new window should open. Open the file Contents/Info.plist by double-clicking on it. Change the VMOptions in the Java-section to reflect other memory settings.
  • On Linux: open the via shell script in your favorite text editor. Search for the line that starts with JOPTS=, and change the settings to your requirements.
