Hi,

I have a problem TRNSYS 17 (version 17.00.0025)-Contam (version 3.0.1.1) coupled simulation to modelling multi-air nodes of monozone building (i.e 12 vertical stacked air nodes). A message is displayed on simulation log (for type 97) : ‘the multizone air flow model did not converge in the maximum number iterations’

However, if I use the previous version of TRNSYS-17 (17.00.0019), the simulation is running properly. I have tried to check on source code file of Type-97; the latest version (TRNSYS-17.00.0025) uses ‘Type97.f90’ while other uses (Type97.for). What is different?

What should I do to make this simulation running properly on version 17.00.0025 of TRNSYS 17?

I am very happy if some one would like to share the information

Thank you

Remon
