TUFLOW Message 0623

TUFLOW Message
CHECK 0623 - No write permission for: <filepath and filename>. Skipping.

Alternate Message
NA

Message Type
CHECK

Description
TUFLOW has been not been able to open a file with write permission. This can only occur for some output files, with the most common file being the "_ All TUFLOW Simulations.log".
There could be a number of reasons that TUFLOW is unable access the file in write mode including:

• User does not have write permissions for that location or file.
  
• Another TUFLOW simulation (or another process) currently has the file open.
  

This check message can not occur for files such as the .tlf which are unique for each simulation and must be written, for example the .tlf file. As TUFLOW has been unable to open the file, no entry will be written for the simulation, but the simulation will still run.

Suggestions
Check the user has write permissions in the location.
If the user has the correct permissions, the most likely reason is that numerous simulations are started at the exact same time causing conflicts. To prevent this, avoid batch files that start multiple simulations at the same time (in a batch file the command timeout <number of seconds>, e.g. to create a 10 second delay use "timeout 10").
If the simulations log file is not required this can be turned off with the .tcf command "Simulations Log Folder == Do not use". Refer to TCF Appendix of the TUFLOW Manual for more details.
