Hello everyone,

I am using an Eulerian domain to simulate the propagation of air in a city environment. I would like to refine the mesh only in specific regions of the Eulerian domain. Is there a way to use transition elements in Abaqus? I have tried partitioning the domain and using the Sweep technique but I am either getting distorted elements and/or Abaqus is forcing me to refine a much bigger part of the domain. 

Thank you

Nancy
