(previous) simula- tion run. A menu appears after a *.dac file has been loaded. When invoked, the Postprocessor inspects all saved time steps. After the loading phase, it halts at the last time-step. The Post- processor displays the same diagram windows as the Simulator (see Section 6.1). For transient problems only the values of the saved time steps appear in the diagrams. If only selected time stages have been saved in the postprocessor file, curves may appear ’step-like’. The Postprocessor offers numerous menu items which are described in detail below. TKO cáäÉ fåÑçêã~íáçå This window summarizes all important data of the selected Postprocessor file, e.g. File name , Problem title , Date of file data , Problem dimension , type of Projection , etc. You should select this option to check problem data.

The cur- rently selected time step is highlighted in red color. Initially, the last step of the simulation is selected. By using the browser, you can select different time levels for the Postprocessor evaluation. If you wish to change the current time level, select the corresponding list entry and press the Apply button. The Cancel button keeps the Postpro- cessor at the previous time level. TKQ sáÉï oÉëìäíë ~í `ìêêÉåí qáãÉ iÉîÉä Various postprocessor options are available to view and export the computational results at the selected time level. The Results viewer window corresponds with the Halt and view results window of the Simula- tor (Section 6.4). To end viewing, select the Exit button in the submenu. For more detailed information, see the identical Halt and view results option of the Simulator menu (Section 6.4) or the FEFLOW online Help . TKR _ìÇÖÉí This item is identical to the Budget menu of the Simulator menu (Section 6.5), except that in the Post- processor the budget can also be analyzed over time periods, displaying the flux quantities as diagrams for a simulated time period. The time histories of the fluxes ( Q [m3/d], Q c [g/d], Q t [J/d]) and the fluid masses M [m³], contaminant masses [g] or energy [J] accumu- lated during the selected time period are computed.

    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.
