Validation Rules tab

The main aim for this tab is to control the valid ranges of output values, since some correlations produce invalid values like sand relative density more than 100 percent or friction angle more than 45 degrees. As it is shown on right, if the checkbox for "0 < Phi < 45" -for instance- is removed, no checking will be carried out on calculated Φ value. We highly recommend to keep all options selected. You can also specify the relative density calculation method used in Duncan (2004) formulae.


 

User Interface tab

Use this tab to choose the input / output units system. By selecting Show help button on top-right corner of all forms, a question mark (?) button will appear on top-right corner of forms, by clicking on it, help page for that page will pops up.
