Re: [TRNSYS-users] TRNSYS Message 25



Héctor,
In the loop that you pasted, try opening up all the links that go into the equation. One of the equation "inputs" will probably be blue instead of black, indicating that it does not have a connection. If that is not the case, I would recommend sending your *.tpf to your distributor to get their help in finding the cause of the problem.
Best,
David

In my project there are a lot of "copy-paste" objects because I try to simulate a solar field with many loops. The problem appears in one of the "copy-paste" loops but in the loop before there isn't any error, then I think is because to other mistake. I've modified transysconstant.for to make bigger the parameters and I've kept an eye to the neweqn.for but I don't know where is my error.
Thank you very much Jeff.
