TRNSYS array limits

The size of variable fields (arrays) in the source code of TRNSYS are partly dynamic or static. The static arrays are defined in the module „TrnsysConstants“ (see \Trnsys18\SourceCode\Kernel\TrnsysConstants.f90) .
If the default settings there have a restrictive effect, the settings can be adjusted. However, the TRNdllxx.dll must then be recreated with a Fortran compiler. If you cannot create a new TRNdllxx.dll, please contact our hotline.

The multi-zone building model (Type 56) has the following limitations:

  • maximum number of inputs 999
  • maximum number of outputs 999
  • maximum number of surfaces 999
