    Thanks Milos.  The benchmarking thing is a good idea...if we ever get round to it!
  • Re: ask for setting a drain node constraint?

    Hi Mingo88,

    To set up a seepage face boundary, you need to get into the "Flow Boundaries" menu.  You need to change the option below the mesh inspector to "options" instead of "assign".  If you then click on the "Head (1st kind)" button in the top left then you can choose the option "seepage face".  You'll need to switch back to "assign" again, before you can start adding the seepage face nodes to the model.

    Hope that helps.  If it doesn't make sense then let me know and I can send a screenshot to explain it.

    Actually think I have worked out how to do it from the line sections option in the results viewer... :)

  • Re: ask for setting a drain node constraint?

    Hi,
    As far as I know, if you're using 1st kind boundaries (head), then they can only be constrained by flux, so putting the min and max elevations in the constraint won't make sense.  To set up the 1st kind boundary as a drain (outflow only) then set the head value at the drain elevation and set up the constraints so that the qmax = 0.  This should ensure the boundary allows water only to flow out of the model, not in.  If the calculated head at this node becomes lower than the head you have specified for the drain, then it will become inactive.

    A quicker way to do this is to input the boundary as a seepage face type - that does the same thing.  You need to change first kind BCs to seepage face via the boundary condition options.

    Hope that helps,

    Peter,

    Thanks for that information.  It will be very useful in trying to work out which machines will be fastest for running FEFLOW.

    Peter,

    Thanks for that!  I'm also wondering if there are any general rules of thumb on how the various properties of my computer such as memory, RAM, processor etc. will affect the speed of a model run.  Does that depend too much on the particular FEFLOW model?  I'm just trying to figure out which of our company PCs will be the fastest for running regional, 3D variably-saturated FEFLOW models.

    Cheers,

  • Parallelization of FEFLOW?

    Hi,

    Just wondering if anyone can explain how the parallelization of FEFLOW works?  Does this mean that even if I am just running one model, it will be quicker to run it on a multi-core machine?  If so, then would a quad core be more efficient than a dual core, or are there only ever 2 processes running simultaneously?  Thanks!

  • Re: How to get a cross section of a 3D model domain?

    Just wondering - is there anyway to export the data from the cross-sectional view of the model results in a format that would allow me to easily plot up the contoured heads or pressures on any 2D section cut through the 3D model?
  • Re: Export and import of hydraulic properties

    Thanks Michael.  Sounds good.  Do you know if there's anyway to import a polygon of uniform properties, rather than Feflow contouring them at all?

    Cheers,
