end-of-file during read error message

Thu, 09/20/2007 - 9:05am — nadiasalem24
Hi all, I am running w2_cvf.exe on Windows XP and when i double click on it i get an error message saying forrtl: (24) end-of-file during read, unit 60, file ... and then lists several unknown routines. I appreciate any help. Nadia

Make sure you run the preprocessor first before running the model. This sounds like the model is looking for data in one of your input files and the model can not find it. You need to make sure all of your input files have data which covers the time period from TMSTRT to TMEND.

I ran the preporcessor and it runs through the bathymetry file and get the bathymerty file checks and the last line showing is water surface elevations. No error messages and it just stops. Thanks. Nadia

It sounds like if the preprocessor stopped on the water surface elevation then you have a error in your bathymetry file (at the top). Check the pre.err and pre.wrn files for information that might tell you where to look. Make sure all of your input files are space "delimited" with no tabs in them. Also make sure everything is spaced correctly in the bathymetry file. This is critical to make sure the file is read correctly.

Rob, Thanks for all your help so far. I have one error left but repeated several times. The errors have to do with cell width and i have copied them below. Since this was the last error, i thought i would copy cell widths from one segment into all other segments (except boundary segments). This took care of the problem but it is an unreasonable solution. Finally, since i got zero errors when i made that change, i thought i would run the main program but unfortunately, i got an error on that even though the preprocessor gave no errors. The error i got reads "forrtl: severe (24): end-of-file during read, unit 94, file ..." I was not sure what it means when the preprocessor runs with no errors but then you get an error running the main program. Any advice would be greatly appreciated. Thanks.

Nadia, The information you provided seem more like they came from the pre.wrn (warnings) than errors. If so they do not necessarily need to be corrected. You solution to correct them though is inappropriate. These warning come up whenever the bathymetry widths between two adjacent cells (vertically or longitudinally) changes by more than 7x because this can potentially result in model instabilities. The preprocessor check most for files for many things but it's improssible to check for everything. So the model error indicate syou still have a problem with one of your input files.
