Lines checker

The Lines checker tool enables checking lines properties by displaying them as curves. These properties are those that are directly used by the solver, such as for example the outside diameter (OD), the buoyancy diameter (diamB) or the axial stiffness (EA). For each line of name LineName, the values of properties are read from the file LineName.txt created by the solver. Lines positions are those before static calculation.

To open the Lines checker, click on the icon from the toolbar.

Defining curves

To define curves, the user has to fill the curves table which is framed in red in the panel capture below.

A curve is defined by:

  • the line concerned,

  • the X-axis variable of the curve (curvilinear abscissa or Z coordinate),

  • the property name as the Y-axis variable of the curve.

There are three ways to fill the curves table:

  • manually,

  • from an Excel sheet,

  • by using the trees on the left of the panel.

Manually, for each curve, enter the three data (line, X and Y variables names) or use the dropdown lists (as shown in the panel capture for the X-axis variable of the last curve).

From an Excel sheet, a copy/paste can be done to fill multiple curves data in the table.

Note

If the table is empty, you can copy/paste from Excel without opening rows in table. If not, you have to open as many rows as necessary with the Rows number edit box.

If the model has many lines, it can be tedious to select lines with the dropdown list. In this case it is more convenient to use the lines tree on the left since:

  • the tree shows the lines groups which can be expanded or collapsed,

  • only one click on the parent node of the tree can (un)select all the children nodes.

To fill the table with curves using the trees, proceed in two steps:

  • select line(s) in the tree of lines and the X and Y-axis variables in their corresponding trees,

  • apply your selection with one of the two buttons image alt V and : the data are passed into the curves table. If the table is empty clicking either button has the same effect, otherwise, the button Replace remove all previous data in the table.

Displaying curves

A curve is ready to be displayed when it has been built before. To build curves, the user can:

  • build only one curve with the **Build** button in the last column of the curve row,

  • select multi-rows of the table and click on the **Build** button above the table,

  • click on the **Build** button placed on the right of the curves table: in that case, all the curves are built at once.

Once a curve has been built, it can be displayed by clicking the **Display** button.

The curves can be outputted in several formats (text file, Excel file, ...) by clicking on the buttons placed on the right of the graph area.

The button can be used to switch X and Y axes on the graph.
