There's a detailed description of the batch mode in the FEFLOW help system: Open help, go to 'Top' level, and hit the 'Batch mode' button. From FEFLOW 5.4 on, there is a completely graphic-less executable. Using this graphic-less mode can save time, especially compared to a simulation where results of all the time steps are rendered. The advantages compared to a simulation including graphics, but without updating for all time steps are less significant when looking at one single model only. However, the startup time of the graphic-less executable is shorter, so this option has advantages when running large numbers of small and fast-running models, e.g., in parameter estimation or optimization.

You can disable the velocity plot by turning velocity vectors off in the legend editor. Refreshing of heads can be limited to certain timesteps using the settings in 'Control output'. In models where the calcultation is fast, but the drawing slow (many elements, relatively simple conditions) this can save a considerable amount of time. In FEFLOW 5.4, a completely graphic-less batch mode is available, too (executable feflow54c.exe).

I'd put the seepage face both to the bottom and slopes. The flows can be calculated using the budget analyzer or an observation point group. The fluid flux analyzer is not suitable here.

Talking about other parameters, you have to make sure that the density ratio and reference concentrations are put correctly. I would try to not use upwinding techniques and keep the dispersivity in a reasonable range.

No, this is currently not possible with the BHE module in FEFLOW.

FEFLOW is limited to dissolved species. It does not do multi-phase simulations.

You'll need a flash player to see the animation.

The new link is http://www.feflow.info/320.html. However, this will not work in FEFLOW 5.1.

Solution: there are a module named "simpleOpenLoop" in Service & Support » Solutions & Extensions » Existing IFM Modules.

Sometime the injection flux changes the temperature of water production well by time variation. Can I simulate this new conditions? (the temperature of production flux might be dependent by well injection temperature and the new temperature of well injection will depend by the new temperature of well production :o).
