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.
