Yes I took into account the snap distance. I did the snap distance = 0 as you can see in the document attached which shows the whole workflow I did to input the wells. Nevertheless, and in spite of we checking the wells shapefile to guaranty that only one well per element and per node rule was obeyed [b]BEFORE[/b] trying to input this shapefile into the model, I get an error message during the input process (as you can see in the workflow attached) and in spite that [b]BEFORE[/b] input the file we also checked to guaranty no well would be located into a BC, FEFLOW ignored almost all the wells in the files and displaced the ones it considered to the nearest BC (which so happens to be H = cte). So it clearly is not a snap distance problem. What then is going wrong!!?!!?????? >:(
