So strange that it worked at the uni of several computers but not on my laptop at home... Could it be windows vista?

Thanks for the quick reply. But I do not use named range, I use this input:
GET XLS DATA('Inputs.xls','August','A', 'E3')

I use 5.2 DSS by the way (which seems to be an old version, but the only one available on my university...)

Dear all, I was working in my model on another computer and everything worked fine. Now I am working on my laptop en get this error: ERROR: Range (or named range) R3C1:R52C1 in file Inputs.xls (sheet August) incorrect or noncontiguous. ERROR: Unalbe to get data values for "E-demand per hh (J)&q...

thx

Dear all,

I get a warning when I try to use data from an excel file:

WARNING: Simulation starts before first time for exogenous variable - "X"
WARNING: Exogenous variable - "X" - in range at time 1


Can I avoid such warnings?

thx

Dear all, I would like to model different CHP (combined heat and power) installations who in total have to fullfill a certain (provided) energy demand. All generators are initially the same, but store their heat in a heat buffer. CHP's with a full buffer are switched off. This will lead for example ...

Hi everyone, Instead of adding 20layers with a copy of the same model, is it possible to use one layer for 20simulations in one run which differ only on one or two parameters? I have an excel file with 23datasets which I need to run simultaneously. Just adding extra copied layers does not seem the r...

Makes sense what you are saying. I changed the model and The Units are okay at the moment. I only don't completely understand your Pulse function as the event trigger. At the moment I have two outflows of my buffer, one being the heat demand of the household and the other being the tap water demand....

Thanks for the reply, but in my model I have a hot water buffer (in Joule) which is filled at a certain (constant) rate in Joules/Minute. But as the buffer is not emptied at a specific rate but rather at specific moments in time (orininating from a excel sheet) the outflow has to be in Joule. But th...

I added the model here. It is my first Vensim model, so every feedback is welcome!
thanks in advance

He everyone,

I have build a model with some 10 unit errors in it. But since the model seems to work just fine, is this a problem?

Dear Tom, thanks a lot for the help! The system like this works indeed. I am only wondering about one the device starting and stopping. YOu devide there with the time step which makes the unit 1/minute. That means that I have to change the unit into 1/second if I change my timestep to second? And I ...

The problem I encountered with the pulse function is that you have to specify a starting time. I only know that the installation is switched on when x>0... Not at what time this will happen

Hi everyone, I have the following problem: I have a electricity flow which is decribed as: capacity * "CHP on" ~J/S capacity=5000 ~J/S CHP on=IFTHENELSE(value X>0,1,0) so the flow will only be switched on when value X>0 which is good. But at the moment the flow starts it needs to continue ...
