[TRNSYS-users] CANT FIND TRANSFER FUNCTION COEFFICIENTS (JUAN FRANCISCO BELMONTE TOLEDO)

[Ivan Flores Abascal]

Dear Juan Francisco:

The problem may be due to a very small thermal diffusivity of the wall  
(low transmittance and high inertia). When I have carried out  
parametric studies varying the capacitance of the wall, I have  
encountered similar problems. I have solved them in trnbuild  
increasing the timebase for the calculation of transfer functions.  
Trnbuild -->Project --> Outputs --> Timebase

Best Regards
