Hi Amogh,
Convergence testing can be done manually or using the sweeo utility. But you are correct, it is going to be time consuming. Would you be able to add an index monitor, something that would capture the bend in the plane it is in. The index monitor has a result called "index preview" for which you don't have to run the simulation. If you compare the two index previews (from FDTD and varFDTD), do you notice any differences?
