UKP sáëì~äáòÉ You can visualize the model domain in 3D in differ- ent view modes: • body, • isolines, • fringed isolines, • isosurfaces and • fences. In each of the view modes one of the model param- eters can be chosen: • hydraulic head, • pressure, • mass, • temperature, • velocity, • saturation, • moisture content, • reference distributions and • material parameters (conductivity). Some of the view modes can be combined; for example, you can visualize fringed isolines for the hydraulic head and add isosurfaces for the contaminant mass. Figure 8.2 3D view.

You can define the cut-out by insert- ing screen related Position coordinates in the menu or by moving the 3D handlers on the body of the model by mouse. UKR m~íÜäáåÉë `çåíêçääÉê The Pathlines control- ler pop-up menu lets you choose different modes of starting the pathlines, types of computation, shapes of the pathlines, and the num- ber of pathlines to be visu- alized. It also allows to import starting points from a database (e.g., for com- puting the relevant area of influence around wells) and to export several 2D- projections of the pathlines. pí~êí Äó Pa Åìêëçê To specify the starting point of the pathline drag the control handlers of the 3D cursor to the corresponding location of the model or enter the exact coordinates in the input text fields. pí~êí çå Oa ëäáÅÉ Select between starting a single pathline or a num- ber of pathlines specified in the input field along a line to draw or around a single well. The current slice field determines the slice at which the particles should start. oÉäÉî~åí ~êÉ~ çÑ áåÑäìÉåÅÉ This option allows the starting of multiple pathlines from a circle around a point at different elevations, e.g. at top and bottom of a well. You can either enter the point data manually or load a specific file ( *.rai ). See the online Help for a detailed description. rëÉ áëçÅÜêçåÉ ã~êâÉêë Choose this option to enable the drawing of isoch- rone markers during the pathline computation. The set button opens a pop-up window for detailed isochrone settings (time levels, final time, and porosity/sorption values). cçêï~êÇLÄ~Åâï~êÇ Isolines can be computed forward from the starting point or backward. Use backward, for example, to cre- ate pathlines starting from a well. píÉ~ÇóLråëíÉ~Çó Pathlines can either be calculated based on the velocity field of the current time step (steady) or - in the postprocessor - based on a specific time period (unsteady).

    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.
