Hi,
There are various types of files you can export which contain the spatial distribution of your input data in text format, e.g x,y,z or as a shapefile. For example when looking at material properties, if you choose the tool "special" (under mesh inspector) a window pops up which gives you the option of saving the property data to a file.
Also if you save your .fem problem in ascii interchange format and open it in a text editor, then all of the input data is in there. There is a guide to the file format in the file_formats .pdf on the Feflow cd.
Hope that helps.
