ERROR 10217 - error opening structural log file, <structure_logging_file>

Description

Raised when the structure logging file (.slf) cannot be opened for writing. Structure logging is enabled via Structure Logging == 1. The file name is reported in the message.

Suggestions

Check that the log directory exists and is writable. Verify that no other process has the file open and that the path does not contain invalid characters. Ensure the user running the simulation has write permission to the log directory. If Log Dir == has been specified, verify the path is correct.
