I've just completed a ductwork system for a Travelodge hotel. I managed to run the calculation successfully but then I've gone back to fix some ductwork sizes on the top floor and added some dampers. Since I've done this I constantly get a runtime error 6 overflow error and then it crashes. Can anyone help please??
This error is usually due to extreme numbers within the calculation. I would suspect that this is because of the specifics of the sizes fixed or the dampers entered.
Could you please back up the project and try unfixing by going to Ducts>Group>Group unfix, and selecting the entire floor in question?
Should the error persist it is likely to be the dampers. If the error persists after deleting these could you please let me know and I can inspect the model for you.

I've backed up the project, removed all the dampers I'd added and group unfixed all the ductwork. Unfortunately I'm still getting the same error.
Hi Pete, ok thanks for testing that, please upload project folder to:
Hi Shane, I've sent the files through for the ductwork netsys. Hope that's all you need but if you need anything else please let me know.
What system marker is giving you this error? I have tried all in the project and all are calculating fine for me.
I noticed that you are on a very old version of the software (v25) which likely explains this. To resolve I would firstly advise installing the latest version, which can be downloaded as detailed here.
