It's straightforward to get FEFLOW to output hydraulic head over time at a single observation point (I can get this as a graph and export a time series of the data points). However, I would like to get an output of hydraulic head along a cross-section.

As a very simple example, if I run a 2D vertical model (steady-state) with a length of 1 km, transmissivity of 250 m2/d, a Fluid Flux BC of -0.5E-3 m/d across the top of the model, and a hydraulic head BC of 50 m at one end of the cross section, I would like to show that the hydraulic head at every point along the 1 km cross-section matches up with what I would predict from solving the problem analytically.

Specifically, I would like to plot hydraulic head values from my analytical solution at several points along the 1 km cross-section, and compare them with the values of hydraulic head along the cross section as computed by FEFLOW. To do this, I would like to be able to export the hydraulic head values along the entire cross-section, but I am not sure how to do that (aside from using the inspector tool to look at the value at each point and then typing that value manually into a spreadsheet). Any help you can provide would be appreciated.

There are two alternatives:

1) Create Observation Points at specific locations and connect them to the reference values. Then go to View - Chart - Hydraulic Head History and you will have the simulated and "reference" heads. Scatter plot is also available. You can find a lot of information how to add Observation Points in the Help System.

2) Export the FEFLOW simulated hydraulic heads. Simply a right-click on Hydraulic Head and the Export Data. You can export values from either all nodes or nodal selection.

Thank you, Carlos. The second option you suggest, for exporting the data associated with selected nodes, is exactly what I was looking for.
