As you found out, Type 557 only allows once instance of this type in a TRNSYS simulation. With several large projects requiring multiple borehole fields, we took quite a bit of time and re-worked Type 557 to allow multiple instances as well as add a few features; namely the ability to direct flow into and out of distinct radial regions in the field. This becomes important when you use the model with radial stratification and wish to explore creative charging and discharging options with the field. This new model will be featured in the new TESS GHP library when we release it for Version 18 in a few months - but we could make it available earlier if people are interested. Please e-mail us off the mailing list if you are interested in learning more.

Dear TRNSYS users,
Currently I am using type 557 in TRNSYS simulation studio. I got the error (the maximum number of instances (1) allowed for type 557 is already reached) when I added the second type 557 to have two separate borehole fields. How can I solve this problem?
Best regards
