Grid Scale
 
Hi everyone.

I have little knowledge about fluent.
The fluent solve perfectly my model without scaling the grid.
When I scale the grid to change the units from [mm] to [m], fluent can't converge the results, using the same boundary conditions.
Do you have any idea why this happened?

I want to know how can I model a heat transfer by radiation between two surfaces? I've tried that radiation s2s, but when fluent try to read the s2s.gz, it shows me an error.

Best Regards.
