Sidharthkp is on a distinguished road
In a transient simulation of mixed convection(rotation of outer cylinder and buoyancy) in an annular gap with a time step size of 0.0001s, i am getting convergence rate value of 1 in first iteration and near zero in second iteration for any given timestep.Attachment 74917

I dont know much about transcient simulation. am i doing it right by this result...
