Conditions along a line

Conditions along a line, under Output Specification → Conditions along a Line, track head or extraction along a line during both a steady and a transient simulation. Tracking extraction along a line is useful for checking the accuracy of the governing equation approximation. Tracking head along a line shows how head profiles evolve during a transient simulation.

• Label is a text label that helps you keep track of multiple lines.
• Level is the model level of the line.
• Coordinates are the coordinates of the end points of the line. Click the edit icon in this cell to open the coordinate editor, and enter one vertex per line, with x and y separated by a comma. To digitise the line on the map, click the draw icon and then click each vertex; double-click to finish.
• Points on Line is the number of points on the line where head and extraction are computed. More points yield smoother, more accurate profiles at the cost of more computation.

After solving, graph the line with the plot results icon on the row, or right-click the line on the map and choose Plot. You can also extract conditions along a new line after solving, using the line probe on the map toolbar. The line probe will extract and graph model results along the line at all levels and timesteps for all available model variables.
