      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
