I have meshed a general block volume and I'm trying to use PATH along with ESEL to select elements in the neightbourhood (of radius "R") of a given element "i".
I use *DO to insert the X Y Z coords of a spherical path around " i " into PPATH,
then I issue ESEL,S,path,"MYPATH" to select elements, the expected result is a set of elements containing those around "i".
the problem is that, although the array of coordinates XYZ does not contain the value (0,0,0), the selected set of elements includes a "tail" of elements that goes from the origin to the element "i" as if the path defined by PPATH wasn't only a sphere of points but the sphere plus the origin, and that behavior holds for any element.
