Shuai,<br>
The *** syntax is a special code recognized by the TRNSYS input
file processor to mean "append the name of the input file onto the
specified extension"<br>
<br>
before modification of the input file, you should find files called
combisys.ou1, combiSys.ou2, etc.<br>
<br>
By deleting one of the three asterisks the processor now thinks
that the output file names should be:<br>
<br>
**.ou1, **.ou2. It will no longer append the name of the input file
onto the specified extension. <br>

<div bgcolor="#FFFFFF" text="#000000">
Richard,<br>
It is important to clarify that the data file for Type927 required
at least two <i>values </i>of source and load flow rates in order
for the TRNSYS kernel routine that reads the data file to
interpolate correctly. A modification has been made to TRNSYS 17.1
that allows users to specify only one value for any of the
"independent variables" if they so choose.<br>
<br>
The easiest thing to do in Trnsys17.0.x and earlier is simply to
copy the data for the flow rates that you do have and paste it for
another (arbitrary) flow rate. Essentially this just indicates in
the data file that there is no performance dependence on a changing
flow rate. Probably not a great assumption but at least the
simulation would run. <br>
<br>
Kind regards,<br>
David<br>
