Is there a pre-existing way to export a 2D model to VTK format?

Or, if anyone has done this before, how did you achieve it?

I am trying to export the mass concentration and mesh into VTK for further work. Apparently v7.1 does export VTK, but I can not see anything in the 2D menu.

You have to export a selection to VTU. Go to the [b]Selection Panel[/b] and right-click on a selection of interest. Choose [b]Export[/b] from the context menu. Please note that the current implementation exports geometrical items of the mesh only. Scalar or vector quantities are not supported yet. As a workaround, you may export the mesh as an ASCII based file and modify the file with scalar quantities (e.g. mass concentrations) you previously exported into another file your you previously retrieved via the FEFLOW API (C/C++/Python).

Thanks Bjorn.

Are scalar/vector export options being worked on for a future release?

Yes, that's in discussion. A decision has not been done yet. Anyway, the creation of the mesh is a good step in this direction and adding manually or automatically scalar or vecor quanitities to an existing mesh is easier than creating the mesh.

We'd like to use Paraview more to plot Feflow model properties and results. We have tried with one model and we can see advantages in doing so. Has there been any update to whether scalar or vector data from Feflow can be written to *.vtu or *.vtk format?

Also, for model results like water levels, is the only way to export them from Feflow to Paraview is to export it as ascii (xyz) data?

There are no updates related with the VTK/VTU-writer. Accordingly, I suggest to write a FEFLOW plugin in C/C++ or to write a Python script. The file format description is quite complete:

If you want to visualize water levels I suggest to write the pressure in the vtk-file. You may retrieve the pressure from the FEFLOW API. Here is an example in Python which shows you how to retrieve the pressure.
for node in range(0, doc.getNumberOfNodes()):
print doc.getResultsFlowPressureValue(node)
In Paraview, apply the contour filter ( with a value of 0 kPa on the pressure array.
