TUFLOW Message 2236
WARNING 2236 - ZPT XF file is an old version or wrong format. XF file not being used.
WARNING 2236 - TIN XF file is an old version or wrong format. XF file not being used.
As of the 2010-10 release TUFLOW automatically creates a binary dump of selected input files. This allows TUFLOW to vastly speed up the start-up process next time a simulation is carried out. If the original input data does not have a save date later than its corresponding XF file, the XF file is used in preference to the original data. For more details on XF files see Section 4.13.2 of the 2010 TUFLOW Manual.
This message is occuring as TUFLOW ecountered a XF file in an old or incorrect format. Original zpt layer or tin read instead. TUFLOW will attempt to read the original dataset and ignore the .xf file.
XF file may have been created by a previous (beta) version of TUFLOW, deleting this file will cause TUFLOW to recreate it, next time the simulation is started. The creation of XF files can be globally turned off using the .tcf command XF Files == OFF, this can also be turned off for individual files such as Read GIS Z Shape XF OFF.
