  sir
  
  I re- created axisymmetric model in DESIGN MODELLING and successfully created parameters.
  
  I calculated solution for NUCLEATE FLOW BOILING in Fluent.
  
  Solution is not converged.
  
  Error statements:
  
  # Divergence detected in AMG for pressure coupled: protective actions enabled!
  
  # Divergence detected in AMG for pressure coupled, temporarily solve with BCGSTAB!
  
  Experiencing convergence difficulties - temporarily relaxing and trying again...
  
  Divergence detected in AMG solver: pressure coupled temperature
  
  Error at host: floating point exception
  
  Error at Node 0: floating point exception
  case check:
  Review flow specifications at inlet boundaries. Default values detected.(boundary conditions)
  Please anyone help me how to rectify above errors..
  
  I attached my SETUP file & ANSYS TUTORIAL file in google drive link: https://drive.google.com/file/d/1CBPO3m2ksYqkCVg8TXgLn5jQQ03iedIO/view?usp=sharing
  
  Thanks
