Is it possible to interpolate material properties in FEFLOW? It works fine for any nodal property, but I cannot get an interpolation to work for an elemental property. I have an interpolated K distribution resulting from a pilot point PEST approach, but I would like to make a couple of manual adjustments whilst maintaining a smoothed interpolated K distribution. How can I do this? I had tried to do this with external software and then re-import the new interpolated data, but FEFLOW does not seem to want to import XYZ data for Kriging of elemental values.

You can export the K distribution from the fem-file assuming you already saved the fem-file with the optimized K-values returned by PEST. To export the values go to the Data panel and right-click on the K values. Choose [b]Export Data => All Elements => As Center[/b] from the context menu. Manipulate the export file with the external software of interest. Load the manipulated file in FEFLOW and make a Parameter Link as usual.
