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