About the warning in the .dia file from output regarding grid file. https://dlt-acc.firelay.cloud/c/message_boards/find_thread?p_l_id=3228466&threadId=5078420 2026-05-12T12:31:48Z 2026-05-12T12:31:48Z Victor Chavarrias https://dlt-acc.firelay.cloud/c/message_boards/find_message?p_l_id=3228466&messageId=5079873 2022-05-20T16:24:57Z 2022-05-20T16:24:57Z

Hi, <br /><br />I am copy-pasting the answer from Arthur van Dam, expert in these matters. <br /><br />&#34;Could not read net cells from NetCDF file &#39;gridfile.nc&#39; (is not critical).”<br /><br />Some of our older grid files only contained the grid points and edges, and not the grid cell-to-vertex administration, so dflowfm then automatically determines all of the grid cells. This is why it not critical at all.<br /><br />If the grid cell administration IS in the file, it is simply read in directly.<br /><br />“setbedlevelfromextfile: Using bedlevel as specified in net-file.” <br /><br />This is not really a useful message: IF the _net.nc file contains bed levels, they will be used. If the _net.nc file does not contain bed levels, these may also come from the inifield file, or old ext file, but still the same message is printed.

I was going through the diagnostics file of my model output and saw this Warning saying &#34;Could not read net cells from NetCDF file &#39;gridfile.nc&#39; (is not critical). Then later I saw another INFO: saying &#39;setbeadlevelfromextfile:Using bedlevel as specified in net file&#39;. I was curious to know what this means. Is it a thing to consider or just one of the processing steps which can be ignored. I created the grid file and merged that with the bedlevel in GUI to get a combined grid file. The model is working fine but just wanted to be clear on these diagnostic messages. Thank you
