Output files
The solver outputs global simulation results in binary files with the extension .imp. A header file impetus.imp is created when the simulation begins and each frame that is being output is written to its own file (impetus_0000.imp, impetus_0001.imp etc.). The output interval is specified in the command OUTPUT. The global output is complemented with a set of ASCII files having the extension .out. The data in the .imp and .out-files can be read and visualized by the IMPETUS Afea GUI.
