what should i do? warning is "Reference distribution BHE-dT and BHE-dp not defi

I use FEFLOW 6.1 with BHE.
I set up the BHE model. and run with standalone. and then appear following message.

"Reference distribution BHE-dT and BHE-dp not defined - BHE module deactivated!"

but it's running.
Do i ignore that warning? or What should i do?

Thank you.

This message shows if the nodal distributions that the plug-in BHELoop expects are not defined. If you work with FEFLOW 6.1, this plug-in is actually not necessary as FEFLOW itself provides the plug-in's functionality. In older FEFLOW versions this plug-in was required if you wanted to prescribe a temperature difference between BHE inlet and outlet but in the current version you simply use the BHE boundary condition and the options "Temperature difference" and "Power difference".

It is my mistake. I use FEFLOW 6.0.
your reply is very useful.

but we defined nodal distributions and so on.
and we received same warning message.
when we ignore message and going on.
then we have got results as expected.

Also when we excluded BHE loop in the BHE modules(BHE Integrator and BHE Loop),
we did not receive above warning message.

[size=12pt][i][b]do we should ignore that warning message? or excluding BHE loop, is it OK?[/b][/i][/size]

When can we use BHE loop?

Thank you very much.
