The Problem editor also allows the definition of the simulation type and the editing of the simulation-control parameters. The following main menus are available: mêçÄäÉã Åä~ëë Serves for editing the title, general type of problem (saturated or unsaturated media), problem class (steady or transient flow or transport simulation), projection, and the handling of free surfaces. qÉãéçê~ä C Åçåíêçä Ç~í~ Sets parameters which control the simulation run and offers input tools for time-varying data. PaJpäáÅÉ ÉäÉî~íáçå Configures the vertical extent of the layer and the geometric relations for a 3D aquifer system. cäçï Ç~í~ Provides submenus for the setting of all parameters defining a subsurface flow problem (Section 5.5).

    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.
