Dear Victoria,

Please make sure that you have a reasonable convective heat transfer coefficient for your exterior surfaces. When my HTC was set to zero, I received these errors at every timestep. It could also possibly be a number of different issues such as sending to much conditioned air into the space.


Best regards,

Matt Duffy

Subject: [TRNSYS-users] TRNBuild-Warning because of convergence

Hi!!

 

I´m simulating a TRNBuild project and a warning appears each timestep. The warning says: " Convergence of COMIS-TRNSYS iteration not attained within 50 max. number of internal iterations!" . I´ve never seen it before! Does anybody know why this warning happens??

 

Thank you very much!!

 

Best,

 

Victoria
