  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.
