Learning a new type of modeling software can be an intimidating task, especially for someone who has not done a lot of previous modeling.
ALL DYNSYSTEM codes use a common library of simple commands. Because of DYNSYSTEM's familiar user interface amongst all of the code components, it is easy to use any of these components once you learn how to use one.
Below is an example of a DYNFLOW code used to complete a steady-state flow simulation run. Notice the simple, intuitive commands used.
!Sample.cfi - Simulation fixed heads
!Restore starting save file containing grid and material properties
!Set elevations for all levels
ELEVATION READ topo.elv LEVEL ALL
!Set boundary conditions
HEAD READ sample.hds
