I am using FEFLOW 7.5 and want to assign a constant head boundary condition to several lakes on the top of my model. I want to assign data from the shapefile for lake polygons however when I create then link, select all polygons I receive an error 'invalid pointer' I follow a similar procedure for assigning conductivity (except for assigning a slice number) Is it possible to assign BCs automatically like this in FEFLOW? or is something likely wrong with my procedure?
