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
