Convergence information

Good afternoon,

I am using the IDA solver and wanted to know if there was a way to get more convergence information from the solver in between time steps. So during the non-linear newton iterations is it possible to get local truncation error info or any other convergence info like L2 norm or the like? I mainly need this for debugging purposes. For certain applications I notice the time steps shrink drastically when there is  not much going on in the particular equation set I am solving.

 

Any help with this would be greatly appreciated.
