Hello all We are pleased to announce that we are transitioning to a new website (same www.tuflow.com address) over the next day or so which will change the URL to the forum. Whilst old URLs will be redirected, should you have any shortcuts to this forum it is recommended to change from the old link (https://www.tuflow.com/fvforum/) to the new link (https://fvforum.tuflow.com/) to maximise access speeds. The TUFLOW Wikis will not be affected by the changeover. Please note that during the transition the website and the forum will experience outages. Once the transition has completed we will make an announcement on this channel. Apologies for any inconvenience during the transition and we look forward to showing you our brand new website. Should you have any queries or experience any problems after the transition, please don't hesitate to contact support@tuflow.com. Best regards The TUFLOW Team

Hi Xixi, We have not compatibility tested the full toolbox on Matlab 2013b in quite some time. I can confirm that it works on 2017b - onward at this stage with certainty. However, that error makes it appear as though it is to do with the input datatype. It appears that one of the inputs is a cell array which is not expected. Its possible that whatever script is calling this function is treating variables in a different way in 2013b compared to 2019b. Do you require 2013b for a particular reason? or are you able to proceed using 2019b (or later)?

Hi Toby I have errors when using the code 'ts_000_create_profile_file_WQ ' (tutorial provided by tuflow fv) in Matlab 2013b. It says: Undefined function 'fv_create_profiles' for input arguments of type 'cell'. Error in ts_000_create_profile_file_WQ (line 38) fv_create_profiles(tfv_resfile,out_name,output_sites,site_names); When I use it in Matlab 2019b it works. Could this error because of matlab version issue?

Hi Xixi, Can you please try opening your .2dm in your preferred mesh generator, renumbering the mesh and saving it off. In SMS this can be done via the Nodes>>Renumber option. Whist this should only renumber the node order can you please check that your nodestrings remain in the same order just to be safe. It’s possible that previous edits to the mesh may have led to some ‘gaps’ between node numbers (for example skipping from node 10 to 14, rather than 10,11,12 ... etc) that in turn has affected the nodestring processing routines. By renumbering, these ‘gaps’ should be removed and the model should initialise correctly. We have put in a fix to better handle meshes that are not renumbered to avoid these types of issues in future and this will come out in the next release of TUFLOW FV. Thanks very much for sending in your query so we could fix it, we are most appreciative. Kind regards, Mitch.

Hi Toby I have this error when I run my model. I created nodestrings in SMS however I have used shift key. The most strange thing is that this happens when I am trying to add some new nodestrings (e.g. nodestring 7,8,9), and then has the error for nodestring 1,exactly the same as you posted here. Do you have any idea about that? Thanks

I have similar issue. The simulated flowrate is greater than observed flowrate in some peak conditions.
