Here are the pictures!

Im sorry didnt know! The picture in line are below
In the model the up and down small parallelogramms are wall concrete, and between the parallelograms and wall(concrete) are the air gaps. Furthemore the else lines are there for the structed grid.

There's nothing obviously wrong with the set up. What is the problem?

[StefanosPur]

The problem is that the residuals for continious equation is about 1e-01 . I'm using residuals (absolute criteria) 1e-03 and it doesnt converge. This cause problem in accuracy of the results, doesnt it?

[Rob]

Put some monitor points into the model, what are they doing? Residuals not dropping, ie doing what you're seeing can mean you have some slight transients in the flow that mean the solver won't converge (numerically) but the solution is stable.
