Ewen,
It's very likely a tolerance issue. The humidity ratio is changing by such a small amount that it's not flagging the connected units to be called again. Tighten up your tolerances, or take a different unit of humidity ratio as input (grains for example) to your type. Also make sure your model is being called at least once every timestep.

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 ?
