timplt

The timplt utility is now obsolete and no longer being maintained.

timplt may be used to extract information stored in a time history (.cth) file, and create a GENPLOT file for post-processing. Time history files are created during a Wind-US run by using the HISTORY keyword This is useful in tracking the values of certain specified parameters over time in an unsteady flow.

The timplt utility is used with .cth files created using Wind versions prior to alpha 5.52. It will not work with .cth files created using newer versions of Wind; for those, use the new thplt utility.

Example

Suppose the HISTORY keyword has been used in the form

   History variable pressure frequency 5
      History 1 17 17  1  1 1 1
      History 2 17 17 11 11 5 5
      History 3  9  9 11 11 7 7
