  • Re: feflow - cluster usage

    Can Feflow 6.2 (corporate license structure) run on a cluster now?
  • in-/active elements

    Just installed 6.2 and I'm not seeing the in-/active elements parameter in the Data panel.
  • Re: mass transport: vertical dispersion

    Thanks Peter,

    I assume you meant "less" vertical flow in the last sentence. Would a high contrast (1 order of magnitude or greater) in dispersivity values between layers/elements create numerical problems?

  • mass transport: vertical dispersion

    Greetings,

    I am running a large model that was constructed by Dwaine Edington - he has posted on here several times so you may be somewhat familiar with the model.

    I have set up the transient mass transport component for the model and I am simulating the release of a constituent via mass concentration BC's at selected nodes on the top slice. Currently I am disturbed by the concentrations diving deep into the bottom layers (6 through 9) of the model. I am trying to figure out what is driving the concentrations in the z-direction. I have calibrated the transient groundwater flow model and I am pleased with the results, so I am trying to avoid adjusting the material properties of the flow components. I am curious about the transverse dispersion term - from what I can tell, it is dispersion orthogonal to the direction of flow. I need dispersion in the lateral direction, but not vertical. Are there ways to focus on reducing dispersion only in the vertical direction? I understand you probably do not have enough information to answer my question, let me know what you need and I will provide as much as I can.

    Thanks!
    Humphrey
