m~ê~ääÉä `çãéìíáåÖ Parallel computation tasks such as matrix assembly can be executed parallel using FEFLOW in multi-pro- cessor environments. Specify the number of parallel tasks to be used for FEFLOW in the parallel-process- ing dialog (default is the number of logical processors). péÉÅáÑáÅ çéíáçå ëÉííáåÖë KKK opens a submenu for: • Handling of the concentration and temperature effects on fluid viscosity and density. • Processing of multi-layered wells. • Computation of the mass matrices. • Quadrature rules to evaluate element integrals. • Treatment of elements having fallen dry. • Settings for unsaturated flow. • Reverse flow field option. For detailed information see online Help . iÉÖÉåÇ ÉÇáíçê KKK sets the properties for visualization of the modeling results. Besides switching between linear, logarithmic, or custom scales different resolutions are supported. Customized legends can be saved and loaded again. 1) for more see White Papers Vol. III, Chapter 3 Figure 2.5 Iterative solver settings dialog. mêçÅÉëëçêë ïáíÜ ÛeóéÉêíÜêÉ~ÇáåÖÛ íÉÅÜåçäçÖó ~êÉ íêÉ~íÉÇ ~ë íïç äçÖáÅ~ä éêçJ ÅÉëëçêëK ^ë eóéÉêíÜêÉ~ÇáåÖ íÉåÇë íç éêçäçåÖ cbcilt êìåë áåëíÉ~Ç çÑ ëÜçêíÉåáåÖ íÜÉãI áí áë ÜáÖÜäó êÉÅçãJ ãÉåÇÉÇ íç ìëÉ çåäó ã~åó í~ëâë ~ë íÜÉ ëóëíÉã Ü~ë éÜóëáÅ~ä éêçÅÉëëçêëL ÅçêÉë ~î~áä~ÄäÉ>

Data can be exchanged for preprocessing, during the simulation run and for postprocessing. The interface allows to create additional submenus and menu entries in the FEFLOW GUI, too. The IFM pro- vides support in all phases of building and maintaining user modules. An assistant guides the initial creation process while the project management dispenses with the need to edit Makefiles and others. A callback editor generates the source code for each event you intend to handle. Additional tools and editors complete the mod- ule-development environment.

    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.
