Units System

NovoFORMULA supports both Metric and US Customary unit systems

Toolbar & Menu

Most of the commonly used commands in NovoFORMULA are placed in the top toolbar. For other commands use menu bar. 

Main Page

In order to start a new analysis, press New button from the top toolbar or choose File⏵New menu. The main steps of correlation analysis are described below:

1. Choose the target soil parameter

What soil parameter you are looking for? NovoFORMULA provides you with a list of soil properties which can be estimated based on other parameters (see #1 in the screenshot above).

2. Enter soil parameters

Depending on the chosen target parameter, the table at the bottom-left portion of the page will be populated with the list of the required soil parameters. If the value of all these parameters are entered, then all available correlation for the target soil parameter will be provided to you. However, in most cases we just have some of these soil properties; this will cause part of the correlations be presented. As you enter soil parameters (see #2 in the screenshot), the list of formulas (#3) is updated with more equations.

3. Review the results

Once you are done with data entry, review the list of correlations (see #3 on screenshot). By clicking on each row, additional comments and the actual equation are presented below the table. Based on these comments you may want to remove some of the results from the list by un-checking the box to the left of each row (for example the equation might have been derived for another soil type or geographical location, etc). Once you remove an equation from the list, the average of correlated values will be updated.

 By clicking on "Distribution Chart" button, will show a chart containing all correlated values in a chart.

Enter Known Soil Properties

In order to obtain the results, value of soil parameters should be entered in the table as shown below:

Most of the times, part of the input parameters are enough to provide at least one result; however in order to have the results for all the available equations, all the listed soil parameters should be given tot he program. As parameters are entered, results will be updated.

Adding a Correlation

More than 140 equations are implemented in this version of NovoFORMULA. However, its database is expandable and can grow by adding new equations. User can add new formula by clicking on Tools⏵Add New Formula menu. This will show the screenshot on the left below:

In order to add an equation, NovoFORMULA's standard parameters should be used. For example the equation γw=γd(1+w) defines the relation between bulk and dry density using moisture content. This equation is stored as gwet=gdry*(1+w/100) in NovoFORMULA's database. A list of soil parameters defined in NovoFORMULA can be accessed via View⏵List of Soil Parameters menu, also listed below:

List of Correlated Values

Once you are done with data entry, review the list of correlations (see screenshot below). By clicking on each row, additional comments and the actual equation are presented below the table. Based on these comments you may want to remove some of the results from the list by un-checking the box to the left of each row (for example the equation might have been derived for another soil type or geographical location, etc).

Once you remove an equation from the list, the "Average value" of the correlations will be updated. 

How to export the table into Microsoft Excel

Click on the File⏵Export menu. Then choose the file name and path in the dialog and the table/chart will be saved as an Excel file.

Visualization of correlated values

To better visualize the results of correlations, click on Distribution Chart button. A new page will show a scatter chart for the results which helps user comparing the correlated values and picking the most reasonable range for the soil parameter. In order to view additional information, move the mouse over each point on the graph.

Distribution Chart

A distribution chart, summarizes all correlated values obtained from several available equations on the same chart. This allows user to get a reasonable understanding of distribution of results. For example, as it can be seen on this screenshot, the Cc values generally vary between 0.1 for 0.2 for the specific input data provided to the program.

In order to get the source (name of geoscientist) of each point, simply move the mouse over the point.

Equation Viewer

By clicking on each row on the correlated parameters, its equation will be presented at the bottom-right portion of the page. If you click on this equation, another page (see below) will appear with more feature such as saving and printing the equation.

Reporting

By pressing Print button all correlated results will be summarized in a report. The print preview page allows user change the page setup, print the report, save the report as PDF, and set the zoom level.
