[TRNSYS-users] TrnsysFunctions when using Powell's method

Hi everyone,
I have developed a TYPE that requires use of functions from the
"TrnsysFunctions.mod" module, including "getConnectedUnitNumber" and
"getConnectedTypeNumber". The calls to these functions work properly when
using the solution method "Successive substitution", but not "Powell's

Specifically, when using Powell's method:
- getConnectedUnitNumber always returns a value of zero.
- getConnectedTypeNumber produces a "range check error."

Can anyone help me?

Thanks and regards,
