Hello,
As I press run calculation in Fluent...I have an error

Error: dual_cell_source_term:grid connectivity information not available
Error Object : #f

Can someone help me?

A very late reply, but may be useful for others with this problem....

I had a dual cell error which would prevent the calculation from running- I worked out that this was due to the use of the dual cell model in the heat exchanger model setup. I have been turning this on in order to edit the thermal properties of my inlets and boundaries but have found that once this has been done, the heat exchanger should be switched back off else the model will not run. The thermal data will still be editable and saved even when you turn it back off.

So the fix is to make sure the heat exchanger model is off (or set up correctly I guess!)

P.S. I am also a fluent and CFD beginner, so doubt this is best practice, but this is what I have learnt and made use of whilst playing around with a computational assignment and it works for me!
