Select Relevant area of influence (RAI) in the popped up Pathline-Con- troller . This option starts the computation of path- lines, in backward direction starting from a circle with defined diame- ter around the upper and lower edge of the screen of a well. Select Load in the Control RAI data sec- tion to import the necessary information from a special database named wells.rai . A submenu pops up displaying the database. Select one well and start the pathline computation. You can export the results as 2D projections in different file formats (using the Data Store Manager) or as 3D screen dump (hit <Alt>+<X> on UNIX, <Alt>+ <Print> on PC). Manipulate the setting of the isochrone mark- ers ( Set ) and change the default Options for the Pathline Outfit. After having analyzed the model and stored the results exit the 3D Options menu by clicking on Exiting rotation in the Tricycler window. NMKQKS cáå~ä êÉã~êâë The simulation of the 3D model shows a much more complex situation than the 2D model had indicated. The aquitard leads to different migration paths of the contaminant plumes in the two aquifers. For the model to better reflect the reality, it would seem prudent to take one more step: the temporal variance of the data should be incorporated. The assigning procedure is basically the same as for the transient 2D model. If you have questions, please refer to the context-sensitive online Help which is invoked by hitting <F1> or click- ing on the ’Help’ button. To better understand the theo- retical background of the modeling approach and its implementation in FEFLOW, please consult the Refer- ence Manual. If you have any further questions please contact your local distributor Figure 10.32 3D pathline controller.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
