This section lists most of the error messages that may be produced by 1D Water Quality Solver. Three types of message may occur:
- fatal error messages resulting in the termination of the run (SE1001 - SE1999);
- warning messages that do not result in run termination but should be checked by the user (SW2001 -S W2999);
- notes which assist in the interpretation of the model results (SN3001 - SN3999).
These messages are listed below in numerical order; possible causes are given as well as, where appropriate, the remedial action that should be taken to attempt to cure the error.
If you require further technical support, please contact the support team (support@floodmodeller.com).

Report this error.
SE1401 Error in [zznfile]. Check the 1D Solver files.
Could mean you have not set the system dependent record length.
Either a data error or the record length needs adjusting for you particular system (in readi.f).
SE1402 End of record encountered in the label file.
Check to see if the label file is empty. Try rerunning 1D Solver.
SE1403 Error opening the 1D Solver file zzlfile
Check to see if file exists. Otherwise you may not have read access or it could be a 1D Solver error.
SE1404 Error opening the 1D Solver file zznfile
Check to see if file exists. Otherwise you may not have read access or it may be a 1D Solver error.
SE1405 Error opening the 1D Water Quality Solver output file zzcfile
Check to see if file exists. You may not have write access.
