ERROR 10225 - error writing to file unit<file_id>

Description

Raised when writing to an output file fails during the simulation. The file unit number is reported in the message.

Suggestions

Check that sufficient disk space is available in the output directory and that the directory remains writable during the simulation.

The file name associated with the file unit number should be reported close to the file_id in the log file. Check that the file is not open in another application capable of locking the file and that the filesize is reasonable.
