Manoj,
 
If you have very thin, low-mass walls this can cause a convergence problem. If you do want to model thin and/or very low-mass walls, just use the RESISTANCE ONLY wall type.

Subject: [TRNSYS-users] need help...

Hello,

 
I am working on multizone building. It is having 6 zones.
 
I am trying to define wall type, window type, door type of building in prebid by giving the U value, Capacity, and density values. after assigning the values of wall I am trying save and generate Type 56 files, it is showing following errors 
 
UNABLE TO FIND A ROOT AFTER INDICATION THAT A ROOT EXISTED
 
 CHECK THE WALL TYPE AFTER THE LAST CALCULATED WALL
 OFTEN THE WALL CAPACITY IS TO SMALL TO CALCULATE A TRANSFER FUNCTION !
 
 CHECK ALSO YOUR TIMEBASE !
 
Can any one help me in this regard. I will be thankful to get quick reply.
 
Sincerely yours,
 
Manoj kumar singh
