1D linear interpolation along lines

Hello,

I'm trying to define BC 1st king along the limits of the model by using the data regionalization with the 1D linear interpolation along lines.
The problem is that I have not the possibility to select this option (I have the version 5.4x). Does anybody can help me about this problem?

Can I define these BC like this:

1. Join the "limits of the model.lin"
2. Assign database - import the file.trp (corresponding at some heads on the limits of the model) by the "1D linear interpolation" -  select "Head"- Interactive selection of regionalization points and click on the line ?

Thank you for advace,

Aurélie.

Aurélie,
please see http://www.feflow.info/317.html for a little animation about the usage of the 1D linear interpolation.
