The format and variable names for some of the data in common flow (.cfl) and boundary data (.tda) files written by Wind-US changed between the release of Wind-US 1.0 and Wind-US 2.0. As a result, .cfl and .tda files written by Wind-US 2.0 cannot be read by Wind-US 1.0.
Should it be necessary to restart a calculation with Wind-US 1.0 that was previously run with Wind-US 2.0, the cfrevert utility may be used to convert the current .cfl file to one that may be read with Wind-US 1.0. The .tda file written by Wind-US 2.0 should be deleted, and will automatically be recreated when the calculation is restarted.
To use cfrevert, simply type "cfrevert" and you'll be prompted for the existing .cfl file name, which should include the .cfl extension. The converted file will overwrite the original, so if you need to retain the original file, copy it to a different name before using cfrevert.
It should be noted that Wind-US 2.0 can read .cfl and .tda files written by Wind-US 1.0, so no conversion is necessary when using older files to restart a calculation with Wind-US 2.0.
A terminal session illustrating the use of cfrevert is shown below, for a common flow file named case3.cfl. Lines in a slanted font are typed by the user.
