[TRNSYS-users] Simulation stops with a run time error M6201 when run with large time step

[Joynal Abedin <J.Abedin@lboro.ac.uk>]

Dear TRNSYS users,

My model stops with MATH error half way through when I run it with a time step greater than 2 minutes but runs fine with 2min or less. I have tried varying the time base in TYPE56. I am simulation an multi-zone building with TYPE56 and HVAC systems using TYPE1231, TYPE114 pump, TYPE650 heat exchanger, TYPE24 integrators etc. etc.

What could I be doing wrong.

Thanks for your help.

 

Kind regards,

Joynal Abedin.
