For each point group you have to select a different ID from the Group identifier list first. Their mass and flow balances will be drawn in a special window during the simulation run. Return to the main menu of the Reference Data Editor. For many analyzing techniques of FEFLOW the definition of fences or sections is useful. In the Fences (sections) menu draw one line along the northern boundary, another from the North to the South dividing the model in two equal parts and finally north of the well gallery a line from west to east. These points and lines become part of the finite-ele- ment problem file and can be selected in many menus via their IDs (displayed as numbers at the ends of the segments). All required data have now been assigned now. Before starting the simulation run save your finite element problem , because the distribution of hydrau- lic head will - necessarily - change during the simula- Figure 10.7 Fences (sections).

You can save the file via the Quick access menu or via the shell menu File (default file extension is *.fem ). Saving is possible either in a binary file format, which is faster in writing and reading, or in ASCII file format, which can be read and even edited using any text editor.

As a first test, we only want to see whether our mesh is designed well and if our input data for the hydraulic parameters give realistic results.

Try the different items available in the Options submenu. Check the veloc- ity field. If the pathlines suggest that there are imper- meable sections in the model you likely made a mistake in designing the superelements. Activate one of the line segments you have cre- ated in Line sections & segments and display dia- grams for the hydraulic head distribution. Leave the Halt & view results menu and select the Budget menu. Calcu- late a flow balance for the whole area. Check whether the values are realistic. The total imbalance should be approximately zero for this steady-state simulation.

If the simulation run shows that our flow-only model works well we can now extend it to a flow-and- mass-transport problem. First, we redefine the problem class accordingly.

    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.
