Overland flow module - Pre-processing Error

I have included only the Overland flow module for my work and all the necessary input have been given. I ran the pre-processoe before running the simulation and it ended with the error message "Abnormal Termination". I don't know what could've caused this error. I have included the error report snapshot here. Kindly help.

Hi Ajai,
what version of the software are you using?
The log message is saying that the convoluted boundary polygon is creating some boundary cells that are surrounded by internal cells. This can happen when the boundary shape file has tight loops.
I think this was updated in the latest Service Pack for Release 2017.
If you are not using this, then you may have to edit your polygon to remove small tight loops.

I'm using 2017 release only. I changed the catchment size and orientation parameters in Model domain definition, then it was resolved. The pre-processing ran successfully.
