Hi dear Roozbeh,
I found some issues in data file (hdf) format.
When you open a 'hdf' file, "Assigned Soil Material" don't show in left pane, while if you open a script file (hjs) it will show.
When you solve a 'hdf' model, only Bishop method will show on tool bar, while if you solve a 'hjs' file, all selected solve methods will show.
I send two screenshot to clarify the issues (tutorial8).
Thank you very much.
