Return the element at the given normalised coordinate, nrmCoordOnLine=0.0 at the line start nrmCoordOnLine=1.0 at the line end nrmCoordOnElement=0.0 at the element start nrmCoordOnElement=1.0 at the element end
| nrmCoordOnLine | double | normalised coord w.r.t the line |
| nrmCoordOnElement | double | returned normalised coord w.r.t the element |
| Return value | IFElement | returning element |
