zero in element during solution step

      I created a model in Ansys Apdl (tip and substrate) with range of length between 1E-8 or 10 nm

      I tried to scale it down for 1E-9 or 1 nm from the original model (changing tip radius)

      but after I get through to /solve there are error messages saying  

      for example

      *** ERROR ***                           CP =       9.078   TIME= 14:03:54
       Zero volume in element 14804.                                 

      for many elements

      What is the limitation for the minimal feature size? 

      How do I fix this? Or

      Hi,

       

      Are any nodes made coincident? Did you issue node merge command? Please check the element 14804 and if possible share the details.
