Hi all,


I have set up a model that has an ESTRY culvert directly joining an ISIS river.  The ESTRY channel is connected to ISIS by snapping the downstream node of the ESTRY channel to the ISIS 1d node, and the Conn_2d attribute is assigned 'X1DH'.

Both ESTRY and ISIS have 1 second timesteps.

However, I am getting the following messages in the TUFLOW output window:


External 1D level interpolation outside times ************  0.00000000


I notice that a similar post by John Heald (Jul 06 2013) also raises this query, and the source of the problem was using a mix of single and double precision for the ISIS/ESTRY models. 

I have checked that this is not the case, and have checked the 'Current Version (v3.5)' option for the ISIS Flow Engine Version under the Miscellany tab.  I am using TUFLOW moel build 2012-05-AE-iSP-w32.


Is there anything that I am missing?  Any pointers would be very much appreciated...
