Exports hydraulic heads and optionally concentrations to TECPLOT *.plt format (TECPLOT release 10), so that TECPLOT can be used to postprocess and visualize the results. 2-D and 3-D models with triangular and quadrangular discretization are supported.

Root water uptake from the complete Feddes model. The parameters required for Feddes model implementation such as the number of sink elements considered, the value of pressure head of each sink element and the stress function as well as the width and the area of the root zone, were computed during the simulation period and summarized in ASCII file (*.out1). 8)

This plug-in calculates density effects due to pressure and temperature changes in Discrete Feature Elements (DFE) and finite elements. Density is calculated using the same equations as the BetaGamma IFM plug-in, incorporating pressure and temperature effects (T = 0 ... 350° C and p = 0 … 10Mpa).

The plug-in regards the fluid density related to temperature, pressure and concentration and sets the fluid density after each time step for all matrix and discrete feature elements. The following reference values for concentration C_0 = 0 g/l, C_S = 350000 mg/l, pressure p_0 = 100 kPa, p = 10MPa and temperature T_0 = 0C, T = 350C were set. The density equation of state was adjusted by means of sodium chloride concentration.

This board is for sharing developed plug-ins and Python code between FEFLOW users.

Please follow these guidelines:
[list]
[li]Use a clear subject that describes the purpose of your plug-in or script.[/li]
[li]Make sure to describe the application and application limits in the text.[/li]
[li]Do not attach compiled code to the post, but include a contact email address instead so that interested FEFLOW users can get in touch with you.  [/li]
[li]Python scripts maybe directly included as text or in an attached text file.[/li]

Some often used free plug-ins are available for download from https://www.mikepoweredbydhi.com/download/mike-by-dhi-tools.

The map view in FePEST is currently similar to the Slice View in FEFLOW itself. In case of a tetrahedral mesh, there are no slices and thus nothing is shown. You'd need to use the 3D view in FEFLOW to look at your data.

Hard to tell from the description, but in case the river in reality has a significant clogging layer (and is infiltrating), a switch to a Fluid-transfer BC for the river might be a good idea.

Please try to select Edges rather than Join Edges. With this, it should work.

Hi.

I think it can be done with an IFM plug-in. The ID/labels for observation points are known before the simulation and can be stored in a TXT file. Then, the TXT file can be read by the plug-in, and store the list on a C++ vector. Then, use this IFM command to get the head value at the desired observation points: http://www.feflow.info/html/help/HTMLDocuments/ifm/ifm_api/IfmGetFlowValueOfObsIdAtCurrentTime.htm

Finally, export the output to a TXT file and merge later with X,Y,Z, reference head values. 

Hi.

Indeed, there was a bug. I updated from FEFLOW 7.3 to 7.4 last Tuesday. The right click on plug-in and "edit" did nothing. I decided to uninstall FEFLOW 7.4 and reinstall 7.3.

By going back to 7.3 I recovered the plug-in functionalities but it was a bit complicate. Somehow, Windows 7 removed my user account write access to TEMP folder. So, I couldn't  install or uninstall anything on Windows. The solution to this issue is explained in Windows support: https://support.microsoft.com/en-us/kb/2000547

Is it worth to install the update 4 or stay with the stable version (update 3)?

Thanks in advance.
