[TRNSYS-users] star matrix error



Dear all,

 

I have a project TRNSYS model of a ground source heat pump for building cooling. I used a type56 multi-zone building to model a building, when I start simulation a TRNSYS is brake and show report on list file

 

“the star matrix is singular and cannot be solve

reported information: Star matrix is singular”

 

Did somebody experience this situation and how did you solve it? I would appreciate any help. 
 
 
Thank you for all your assistance

 

Regards,
