Leave the interactive graphics mode immediately and switch to a batch graphics mode. You may decide, if the visualization should be executed or not in future calls to the graphics subroutines. The program repeats up to two different draws (e.g. [Filled] for one component and [IsoLin] for another one) each time. When multiple virtual windows ( [Window] ) are active each of them repeats its current view. The batch mode can be finished by pressing <RETURN> or any other key while the graphics window has the focus (move the mouse into the window or click on the top bar of the window). Then the next call to gebgraf or firegraf enables the interaction menu again. This mode is useful if the program runs in a loop where you want to see the differences in subsequent steps (time-dependency or adaptive meshes). Together with the xxgrab-utility you may produce a series of image files (in GIF format) in order to generate animations.
