>Dear Trnsys users,
>I have been simulating the solar hot water system with a variable flow 
>rate which mainly consists of type 534 solar collector(TESS), type 60 
>storage tank with one internal heat exchanger and four pipes of type 31. 
>Generally, in type 534, if I set the 'pump control consumption' to 1,it 
>will means that we could keep the collector outlet at the specified 
>condition (eg, the outlet temperature of the collector is 55°C) by varying 
>the flow rate. Unfortunately, I tried running many times but it always 
>indicates these error messages that the UAHx of storage could not converge 
>during one time step and the following time step it will use the value of 
>the last iteration. I have attached fiche tpf .
>I would like to know what the problem is about this system.
>I would appreciate any help
>Thanks in advance
