Input of fans (OMEdit) [closed]

edit

I created a model to heat the air of a room. I'm using a fan to transport the air to the room, for now, the input of the fan is a RealInput, and it works nice. However I'm interested in vectors.

I tried to change the block RealInput for RealVectorInput but I have 1 more equation than variables. What am I missing? Moreover if the input of the fan is a vector, I suppose the output, the temperature of the room in my case, will be a vector too, but there isn't any block called RealVectorOutput.

So is it possible to give an input to a fan will change over time?

I'm using the blocks RealInput & Output because I'm interesting to get the results into Matlab.

Thanks in advance.
