• how to correct Delauney criterion violations in n automatic fashion?

    i have a very large mesh with lots of Delauney criterion violations and editing them manually is an highly time-consuming task. So, I would like to know if there is a way to automatically correct Delauney violations and if so, how it is done.

    And after the Delauney violation corrections, how to automatically perform the equilateralization of the triangles?
  • time steps in a multi-species transport problem

    I am trying to define a transient multi-species transport problem but in the simulation-time control panel, if the problem is multi-species, I just get the available option Automatic time.step control. Does this means that, for a transient multi-sepcies transport problem FEFLOW does not simulate for Constant time stes neither for variable time steps?
  • options on time steps in a multi-species transport problem

    Good morning: I am trying to set up a multispecies transport problem in transient regime but in the simulation time control pannel I just get the option Automatic time-step control active. How do I do if I want to use Constant time-steps or Varying time-steps?
  • how to define period budgets

    I want to simulate a transient problem (simple flow) and need to define period budgets but I don't understand how this is done. Can someone help me? Are these period budgets defined in the Problem Settings panel in Prescribes Aditional simulation time steps option? But if I am using the option Varying time steps, how do I do it, once such Prescribes Aditional simulation time steps is not available for such option?
  • editing properties with selections... again

    concerning my former posts on this issue:

    I never used multiple assignment. What I did was:
    1st - selected specific storage in panel Data
    2nd - defined a selection
    2nd - stored the selection
    3rd - selected conductivity in panel Data
    4th - activated the stored selection
    5th - edited the conductivity values in the area of that selection

    FEFLOW edited the values... but reshaped completely the distribution of ALL other properties. So now I have my conductivity OK but all my other properties have just 2 areas with 2 values in the whole domain of the model.

    How can I change conductivity WITHOUTH changing the other properties?
  • Re: selections to edit properties

    No, I didn't use multiple assignment and the error is consistent in the way that if I do the procedure one day and the error occurs. If do Undo eand the following day I do the same procedure, the problem still remains.
  • editing properties using selections 2

    I want to edit the conductivity in an area where the specific storage is =0.01.

    I select that area - while the specific storage acvtivated - and store it in the panel Selections. Then I activate the conductivity, click the selection stored in panel Selection and do the edition.

    In the end I get the area edited with the values I wish for conductivity BUT... all the other model properties and variables are also edited, which is something I didn't asked for.

    In fact, if I had 4 values for specific storage along the model I now have only 2 areas with values 0 and 1. The same goes for the other properties.

    How can I edit the conductivity using this selection WITHOUT changing the other properties? Or is this behaviour clearly a bug?
  • intersections between nodes and elements selections

    I am trying to use selections to edit properties. I want to use a nodal selection intersection with a element selection but altough FEFLOW seems to do this, it also does somethign that I don't want. It changes not only the propriety I am working it but all properties in the model are completely changed and zonal distributions of the parametes are lost. Just the intersected area and the rest of the model are set with values, usually 0 and 1.
    How can I overcome this?
  • selections to edit properties

    I want to edit the conductivity in an area where the specific storage is =0.01. So I selcet that area - with specific storage acvtivated - and store it in the panel Selections. Then I activate the conductivity, click in the selection stored in panel Selection and do the edition.

    In the end I get the area edited with the values I wish foir conductivity BUT FEFLOW also used that selection to change all values and spatial disptributions of all model properties. Meaning that if I had 4 values for specific storage along the model I now have only 2 areas with values 0 and 1. The same goes for the other properties.

    How can I edit the conductivity using this selection WITHOUT changing the other properties?
  • how to import a model into feflow

    I have a very simple model and wanted to import another model to add to this small model. Is this possible? And if so, how?
