I have a fairly large model of approximately 3819 network links. When I run a simulation over several days its creating a huge HYDQUA.OUT file. About 80GB!
Is this normal? The model run finishes but disk space is very low causing issues with graphs and other programs.

My system:
Processor - Intel(R) Core(TM)i7-4790 CPU@3.6GHz
Installed memory (RAM) - 32GB
Operating System - 64-bit
Disk Drive - SAMSUNG SSD 2.5 SCSI Disk Drive

I'm looking for some suggestions. Also can the HYDQUA.OUT files be deleted to free up space?
