[TRNSYS-users] user type, pb of input value due to number of iterations

[ewen raballand]

Dear users,

I've written a type using as input the humidity ratio of a type 33.
Normally, my type should give me as output the incomming humidity ratio but
it's not always happening... sometimes there is a gap of 1 time step.
I've traced my type (206) and the type 33 and it seems that if the type 33
do 2 iterations at one time step, than my type 206 is using the humidity
ratio of the last time step and not the current one !

You can see here what happens at time 8 :

hum_rat_output_33
hum_rat_input_206
hum_rat_output_206

How can I correct this problem to always have the right humidity ratio as
output of my type at the end of the time step ?

Best regards,
