convergence problem on radiation
 
Hello;
i am neophyte on fluent,i want to simulate radiation flux between two storage tank that ones is on fire with assumption T=1240K and second ones tempreture is 300 k,distance between them is 5 meter,i start calculation with int tempreture=770k and 100 iteration but i recieve this error:
maximum iterations exceeded in radiation calculations.

Error: divergence detected in AMG solver: temperature
Error Object: ()
when i increase iterations numbers error is:

Error: Floating point error: invalid number
Error Object: ()
please help me how can i fix them?:(
