Welcome to the Quokka 2 settings file generator

Welcome to the settings file generator for Quokka 2.

PLEASE NOTE: This page is still in Beta mode and is currently being developed. Please report any problems/suggestions to us.

This page can be used to create the settings.m files that are used by Quokka 2 to define a simulation. It currently only supports structures with front and rear contacts.

Fixed incompatibility problems with European numbers

Import Quokka File

The page will attempt to import a Quokka 2 settings file. Any inputs that are recognised will be added to the GUI. Those that cannot be interpreted will be displayed as an error message and you will either need to manually enter them or fix your settings file accordingly.

Please select your (*.m) file using the control below.
