Simulation not converging
I am simulating a static structural simulation in which i have imported the temperature data from fluent model. But during simulation i am constantly getting an error "The solver engine was unable to converge on a solution of a nonlinear problem". I have two material in this simulation. First is structural steel (constant properties) and another one is IN718 whose properties are temp. dependent. Can anyone explain me the issues and suggest any solution for this
In the figure top material is IN718 and bottom material is Structural steel.
