[TRNSYS-users] Increasing the maximum allowed number of equations

   In order to increase the maximum allowable number of equations you 
need to recompile the TRNDll having modified the appropriate line in the 
file TrnsysConstants.f90:

Integer, Parameter :: nMaxEquations       =     500  ! Maximum number of 
equations                                  500

   If you do not have access to a Fortran compiler, please let me know 
how many equations you need and I can recompile one for you.
Kind regards,
