TUFLOW Message 1431
TUFLOW Message 
WARNING 1431 - csv XF file precision conflict.  Re-reading csv file.
TUFLOW exe Precision = SINGLE
Alternate Message 
ERROR 1431 - no arch properties found.
Description 
The data in the binary (xf) version is not the same precision as the simulation.  For example the .xf file has been generated using a single precision version of TUFLOW and the current simulation is running as double precision.
Suggestions 
The simulation is reverting to the raw .csv file.
To prevent a simulation from accidentally being started with the wrong version of TUFLOW, the precision of a TUFLOW can be locked using the .tcf command:
Model Precision  ==
E.g.
Model Precision  == SINGLE 
or
Model Precision  == DOUBLE
