Set the number of simulation years to 10 (Parameter 28).  You are hitting the mesh boundary limit by setting it to one year and then running a 10-year simulation.<br>

Hello TRNSYS user,<br>
<br>
I am using type 557b (Vertical Borehole Heat Exchanger) for my TRNSYS<br>
simulation. I have encountered unspecified error between simulation, for<br>
which the cause is unknown. Can someone help me in these regards? I have<br>
seen that many people encountered this problem, but I couldn't find the<br>
solution in the user forum. I also attached simple Simulation model with<br>
constant heat extraction (10kW) from the soil. In this model, the error<br>
occurs at 83426.164 hours. In case of more heat extraction, it occurs<br>
earlier. For example (at 13225.5 hour 100kW heat extraction).<br>
The error message is shown below.<br>
<br>
*** Fatal Error at time : 83426.166667<br>
Generated by Unit : 40<br>
Generated by Type : 557<br>
TRNSYS Message 103 : The TRNSYS TYPE checking routine has found an<br>
inconsistency in the specified component between the input file and the<br>
information expected by the Type<br>
Reported information: The component model has reported an unspecified<br>
error. Please check the input file for possible sources of error.<br>
<br>
Can anyone explain to me why it happens or what is the solution? Thanks<br>
in advance.<br>
<br>
Regards<br>
Prasanth<br>
