z_phys_nd(i,j,k)=0.5*(z_w(i,j,k)+z_w(i+1,j,k));
This formula isn't right -- we want to average all four z_w values (i,j), (i+1,j), (i,j+1), (i+1,j+1) onto the node

This is a test configuration thing. I just pushed something to development that should fix this -- we were unconditionally trying to deploy the docs to the website, even on pull requests.
