Yes, this is technically possible. You can create an elemental distribution and link this to a specific parameter, e.g. In/out-flow on top/bottom. There are two manners to do this task: 1) using FEFLOW Expression Editor and/or 2) Python function.

Dear Emilia,

The 3D mesh smooth option is mainy intented for 3D unstructured meshes. If you are having a mesh with prisms, I would recommend you to use "2D Mesh Smooth (with X-Y inheritance in 3D".

Hi Jimmy,

You have several options depending on the type of domain (2D / 3D) and mesh (quad, triangular, prism, tetrahedra, etc.). All these are available through the Data panel under the section "Auxiliary parameters".

Cheers

Hi swhit

The answer really depends on the application case. In the case of M21 - FEFLOW coupling, you provide a framework for fully-hydrodynamical coupling. MIKE 21 FM is responsible to solve the 2D hydraulic and send this feedback to FEFLOW. A typical application would be the assessment of flooding events and their interaction with groundwater. Coupling supports mass and heat transport also.
In the case of MSHE - FEFLOW, MSHE looks the problem at the catchment hydrology and supports information not available in FEFLOW, e.g. role of land-use and vegetation in the net recharge estimation, etc. A common application is to estimate groundwater recharge through MSHE and this includes all hydrological cycle. Subsequently such information can be used in a detailed groundwater model in FEFLOW.
We have applied several coupling mechanisms in multiple projects. Let me know if you need more details.

Hi Jimmy,
Unfortunately, the error message is not very clear. Maybe you are trying to assign a parameter type unsupported by PEST. I would recommend you to get in touch with the technical support (mike.de@dhigroup.com). They can investigate the problem deeply and give you a solution.

Hi,

You can use the following script to understand the syntaxis with MLW.

    ## Define Boundary Conditions for Flow
    # NoBC = 0
    # Dirichlet (1st kind) =1
    # Neumann (2nd kind) = 2
    # Cauchy (3rd kind) = 3
    # Single well (4th kind) = 4
    # Gradient-type (only for unsaturated problems) = 5
    BcFlowType = 4

    #Load documents
    doc=ifm.loadDocument(FEM_FILE)

    #Print all Multilayer Well attributes
    for nNode in range(0,doc.getNumberOfNodes()):

        if doc.getBcFlowType(nNode) == BcFlowType:
            if doc.queryMultiLayerWellInfo(nNode) == None:
                print(Normal Well BC found")
            else:
                MLWInfo=doc.queryMultiLayerWellInfo(nNode)
                # Print MLW ID, Name, Top Elevation, Bottom Elevation, Top Node, Bottom Node
                print(MLWInfo.getId(), MLWInfo.getName(), MLWInfo.getTopElevation(),
                    MLWInfo.getBottomElevation(), MLWInfo.getTopNode(), MLWInfo.getBottomNode())

Hi Jimmy,

The FEFLOW IFM package (both C++ and Python) comes together with the FEFLOW installation. Also FEFLOW should create environmental variables, which makes easy to load the IFM module in your Python script.
You should simply need to write "import ifm" in your script to load the FEFLOW Python package.

Hi Christian,

Unfortunately, the workflow is unsupported. The workaround is to copy the X,Y,Z information (typically starting after the second row from the file) to a *.dat file.

The latest FEFLOW 7.4 includes a nodal parameter (Auxiliary data) named "Nodal depth". Such as parameter uses as reference the elevation of Slice 1 to compute the depth. You can easily use the information in any expression as commented above.

Hi,

IfmLake plug-in uses a nodal distribution named "IfmTransfer" with units [1e-4 1/d] to define the transfer coefficients for the lakes. If you can read more details about this implementation in the user manual (page 2).
