Convergence problem

Please login with a confirmed email address before reporting spam

Hi,

I am running a natural convection model and I put the material properties as a function of temperature (interpolation) and piecewise functions. I got results with constant number for the properties which I tetsed for making sure my model is working propely. But when I am using the functions, the simulation enters in a no-end loop. What is the best solution to solve this problem?

Thanks, Reza

Hello,

Not entirely sure what you are trying to do here, but are you sure that your functions are smooth and do not vary too drastically? This could have an affect on the convergence.

Cheers,

Alex
