Description

This is the case when generating a model based on iMOD5 PRJ-file. If the 'irrigation layer' grid contains Nan's in the inactive area, an unclear index error occur when rendering the output file. This is due to the internal conversion to integers.

1- We should have a better input check on this, and raise a clear error message
2- We could use a fill value before the integer conversion. But this needs to be a valid layer number since it is also used as an index, when finding the active cell's.

Research direction

Start at the MetaSWAP Sprinkling class when it renders the output file for models generated from an iMOD5 PRJ-file, focusing on the irrigation layer grid and its internal integer conversion. Determine how NaN values in inactive areas are handled, then verify that the resulting input check or fill-value behavior produces a clear error or valid output.
