[esp-r] New CFC in combination with timestep controller 4 ... ?

[Pueltz, Gunter]

Dear ESP-r developers,

has the new and more accurate Complex Fenestration Construction
ever been tested in combination with timestep controller 4
(several iterations at the same timestep), which is usefull
for modelling the air exchange between several zones within a 
building and the ambient air (natural ventilation by openable windows) ?

I tried the new CFC and succeeded in a standard simulation; but
I ran into problems by using timestep controller 4 (6 timesteps
per hour and even 6 iterations per timestep, Underrelaxing by
RELAX = 0.25) ....

What might be the reason ... ?

Regards,
Gunter
