Hello TRNSYS-Users,
i want to create a Type to describe an adsorbent packed bed, but i
think have a problem with the storage vars. I used it to update two
values of the output (obtained by solving the system of equation for a
time step) to two initial values of the equation's system, to solve
it for the next time step. But really this operation to save a value
of the output and update to an initial value, functions only for one
of these values (t_letto), and only for three time step. After this
time TRNSYS gives me a flat characteristics. Instead for the other
value (wst) TRNSYS calculates it only for the first time step, and
keeps it costant for the rest of simualtion.
I attached the source code for the case anybody would like to look through.
I appreciate every advice to solve this problem.
Thanks in advance.
Vincenzo
PS: t0_letto and w0_letto are the initial values of these two otuput
(t_letto, wst) for the initial timestep, they are inserted like
parameters in the proforma.
