[TRNSYS-users] TRNSYS-EES. Message 129

[Michele Pressiani]

To whom I may concern,

I´m trying to link together TRNSYS 17 (Version 5.4.0.0) with EES (Version 9.920) using Type66a.


The main script in EES is:


$Import 'CLIPBOARD' T_ambient;G

T_amb=T_ambient+273,15 "[K]"
v_wind=3                                 "[m/s]"
k_sub=420                                  "[W/m/K]"
dz_sub=0,1                                "[m]"
T_1=25+273,15                         "[K]"
h=2,8+3*v_wind                          "[W/m2/K]"
h_cond=k_sub/dz_sub          "[W/m2/K]"

h*(T-T_amb)+h_cond*(T-T_1)+G=0

$Export 'CLIPBOARD' T


I set two inputs and one ouput.

For the inputs:

- I used Type 15-6 in order to get the Dry Bulb Temperature (T_ambient) and the Total Horizontal Radiation (G)

For the output:

-I used the online plotter Type 65c in order to visualize T.


In the control cards I set:

-Simuluation start time 12 hr

-Simulation Stop Time 15 hr

-Simulation time step 10 min


When I run the TRNSYS project then I find error related to MESSAGE 129: "The referenced Unit has tried to set an Output value higher than the number of Outputs that the Type reserved for itself."


Then if I check on EES I find:

T_ambient=2,982E+14

G=3,385E+14

I have two questions:
1- Why this values are so high? Am I missing anything?
2- Do I have to put like output from EES all the variables even if I want to see only one of them?
       $Export 'CLIPBOARD' T;T_amb;v_wind;k_sub;dz_sub;T_1;h;h_cond

Would you mind helping me with this problem?
Thanks you so much!

Regards,
Michele Pressiani
