you can send your query at SWAT USER Google Group.

have u got any error during writing input files?? if yes then check that file, soil, lulc etc.

i think u need to check your user soil database file in main gdb file.

Dear Vishal,

 I got my error after writing the inputs. I have checked the files you said.

Thank you for your comment.

Dear Farzad,

Please use a larger DEM (larger area even though your watershed is small), then delineate your watershed. Hope this will solve the error.

Dear Farzad, I got same error as you posted above. Could you please share me how did you solve it. Thanks.

Dear Farzad,

I am facing the same error in my SWAT simulation. Could you please posted you solution with me. Thanks. 

Dear Farzard, could you get any solution? I have the same problem

Regards

I am getting the same error, Did you solve your problem?

Dear Avay Risal,

Check it...may be it has the solution of the problem that you mention above.

In my case I rebuilt the project from the beginning and it worked successfully.

Yours,

This is data input error. Check your soil and climate data.

I am having the same issue when trying to run a project in a newer version of SWAT that I created the model in. Having to rebuild at this point will be fairly catastrophic for me so I am hoping someone has some advice? I was able to run it successfully, but after making modifications to Management it is giving me error (63) output conversion error, unit 28

I have the same error. Were you able to solve this error?

I have the same error. Has anyone resolved it already?

I had a similar challenge, but closed the program and started afresh, it did work the second time.

I had the same problem, in my case helped reloading weather data.

You need to carefully check that the input data format complies with the model

Suddenly when I started having this problem, I solved it by choosing "64 bit, release" instead of "32 bit, debug" in Run SWAT window before simulation.
