Hi! If you have FLAC 3D programme, you should choose Help and then Manual in main menu bar. Firstly you should read two chapters: Getting Started and Problem Solving with FLAC. There are examples how to assign material models and associated properties to all zones in the model. This is done by using two commands: MODEL and PROPERTY. Boundary conditions are normally specified with the APPLY and FIX/FREE commands.
