Problem with air as a fluid ;-)

Dear sir,
While solving my model, I am getting an error that the "Last time step is not converged" if the air is taken as a fluid whereas it is showing the results when air is taken as a solid.
What should I do to get the solution with air as a fluid??

Hi
you need to explain a bit more what you are doing, which dimension , which physics, something about the model
A fluid and a solid are quite different in their properties and the way to approach simulations, even if COMSOL is doing a lot to unify everything.
fluids needs ideally the CFD modules or with the MEMS, but certain simplification to the model can be done fully in "solid" too

Good luck
