Dear all,

I would like to know if it is possible to separate the observation points in different groups in order to analyze Hydraulic Head Scatter Plot separately, for each group.

Thanks in advance for the answers and comments.

At the moment, the FEFLOW GUI does not provide such an option. Accordingly, you have to export the data manually and use an external software (e.g. Excel) to make the scatter plots based on different groups. Alternatively, you could use the FEFLOW API by writing a Python Script, which retrieves the heads calculated at observation points. You can use the API function [font=courier][color=blue]  doc.getFlowValueOfObsIdAtCurrentTime(obsID)[/color][/font] to retrieve heads from FEFLOW. If required, other API functions addressing available History Charts stored within a dac-file are also available. After you received the heads, you can generate an arbitrary number of group combinations. Plot corresponding graphs and save them as graphic files using external libraries (e.g. matplotlib).

in an unconfined aquifer, observation wells for the hydraulic head should be at top of aquifer or bottom? while checking simulation I notice that first slice have high head value and when I go down it decreases

You should try to have the observation wells in the saturated part of the aquifer (in case of using the phreatic or unsaturated option). I'd typically put the observation wells either at the real screen elevation (bottom or center, depending on the case) or on bottom of the aquifer (if it is shallow). Using the top is usually not a good idea.
