I still get the same error. I am running sfepy 2014.4 as that is the most recent version in the Enthought Python Distribution.
Given that you are correct that I should probably use the dw_surface_ltr term I'll try that. I am still just playing around with things (which is why the load was too high - the numbers are made up).

I have been trying to understand how to use the interactive version of point loads. As I understand it, the load have as many rows as the number of points you are applying the load to and the columns must be equal to the spatial dimension.
I modified one of the examples for my own problem but get errors when I try to run it: (Program & mesh file attached). If I use simple displacements as a boundary condition, it works just fine. Any help would be appreciated.
