Running FlexPDE Without A Graphical Interface
Starting in version 6.30, there is a FlexPDE executable that does not use any graphical interface. This is necessary for users to run FlexPDE on systems that do not provide interactive graphics. The executable is suffixed with 'n' (for "no graphics") to distinguish it from the graphical version.
The graphics-less FlexPDE must be run from a command line. For example, the command line
will load and run the script file "problem.pde".
The run can be interrupted by typing 'Q'. The user is then prompted whether to interrupt or not. Type 'Y' to complete the interrupt.
