Hi!
I'm trying to create a time series as a result from a Do loop script.
I want to record the result of each step of the script in the first, second, third and so on day of a new time series, (the days correspond to the time simulation period) .
I couldn't get a solution.
Hope you can help me.
Hi Mruizs,
Thanks for posting in the GoldSim Community Forum! Let me see if I understand your question. You have an array of values that you want transposed into a time series? One way to do this is simply by using the elapsed day as the index. Here is a very simple example:
I have an array that is defined in a Data Vector:
In the case shown above, I have 100 rows in this Data vector. Next, I will write an expression that puts each row's value into successive time values to create a time history for each value as each day passes in the simulation:
As each day passes, we grab the value from the next row down.
Would something like this work for you?
Hi Jason!
Thanks for your prompt answer.
I just realized that in my script It was not necessary to write lines in order to give the order to create a time series as a result.
I just have to select the option "Time History" in Save Results, and work with "DateTime" to call the item from another time series.
I hope you understand my answer.
Hi everyone,
I have a script in Goldsim which requires time series to be fed into it. But, I need to do some pre-analyses on the raw time series and as a results, I have expressions and not time series and it lead to an error when applying the scrip (please see the attched file for what I am looking for). Is there any way to convert back an expression to time series format?
Thanks
Saeed,
You have a couple of options. You can simply run the model, right click on the Precip_Expression and select Time History and view the table of results and copy-paste them.
If that is not what you want, then you can record the output to a time series (i.e. into your Precip_TS_out): Using a Time Series Element to Record and Play Back a History
Please keep in mind that the first option I mentioned is by far the most common and easy to do. The recording option is typically used to pass the entire Time Series definition into a Submodel for further processing inside GoldSim.
Does this help?
Jason,
Many thanks for your response. The point is that I need this conversion (The expression output to Time Series) to be done straight on the ‘Precip_TS_Out’ as it is the input to another Script element which only accepts time series element (e.g. in that script there is a loop which calls ‘Precip_TS_Out(~Ts)’ where Ts is an incremental time step). For that reason, I am not calling the original 'Precip_TS_In’ but need to use the output from the 'Precip_Expression' and this should be in Time series format.
I hope there is an appropriate solution for my case.
Thanks in advance,
Saeed
Hi Jason,
I used the recording function of the time series and used it as the input to the script and now have this error, would you please help me how I can handle it? I also attached the script where the recorded time series is called (red rectangle). Again, when I use the original Precip_TS, the script runs without any error.
Thanks
Saeed
Saeed,
My guess is that you are trying to refer to the time series recording before it had a chance to finish recording. It is important that you wait until the time series has finished recording before using it. To enable this, please try changing your IF statement found on line 9 of your script to be:
IF (ETime >= ~SimDuration) THEN....
Does that work?

Hi Jason,
the solution to change the script, i.e
IF (ETime >= ~SimDuration) THEN....
doesn't work and I had the same issue, but you were right about this point that the model was calling the time series before the recording finishes, and I resolved this by putting it in a sub-model and then called it in the main model and it works fine now.
Thanks for your help Jason.
Regards,
Saeed
