Let's say I have a target of removing 90% of the TSS, could I define a calculated variable as the removal percentage, and then use this variable as the input to a PI controller?

Thanks!

Similarly:

If I remove a certain controller that works properly, then place it again, I get an "interface link undefined" between the node and the controller, despite the arrangement being identical and the method used to link them being the same.

Hello!

I am currently working on a model that runs without problem, I have loopbreakers where I need them, and everything is fine.

However, when I place a PI controller on a centrifuge, I immediately get the error message warning me of an algebraic loop and that inserting a loopbreaker is necessary. Is there a way to work around this?

Also, I would just like to confirm that the data output of the centrifuge is the variable "DS". Is this correct? Thanks again!

Hello!

I'm having an issue customising the plots (fastline or otherwise). If I right click on the plot, all of the menu items with the word "properties" do nothing when I click on them. I'm simply trying to display the units of the x and y axes but it's not allowing me to do so. Have you encountered this issue before? Is there a default unit used for concentration on these axes?

Thanks for the help.

Very good, thanks again.
I tried rebuilding my model block by block and found that my SBR is what is causing issues, so I think I need to look closer at the parameters I am using!

edit to add:

If I load up one of the prebuilt models and load my influent file, everything seems to work correctly, which would indicate that the error is in the assembly of my model, correct?

Hello, I'm having some trouble with a model, I get the error "System Error: Error while executing simulation experiment, reading input file, or evaluating upper and lower boundaries".

This is a bit general, is there .txt file somewhere in the West folder that would allow me to trace the error to a specific block or parameter that isn't working properly? The error does appear while the control center says "building executable model", does this help narrow down the error?

I've also encountered a situation where I specify a certain flowrate in my influent .txt file, and this correct rate is visible in the "Generate and Review" section of the Influent block, but the first block that receives this influent shows a much smaller flowrate coming from the influent. Is this related to the above error?

Thanks again for the help

Thanks for the reply, I was using the combiner to combine the out_1 and out_3 because I hadn't understood what they were. Thanks for the help!

Hello! I'm currently working on a project where the SBR's only have 2 outputs, one effluent water, the other recirculating the solids back to another reactor.
The SBR model in West (2016) however has out_1 and out_3 for water. What would be the best way to model my SBR?

Can I simply leave one of the terminals with no connections (if so, which one should I use?)
Or should I used a 2-combiner to connect the outputs?

Thanks for the help!

Correct, I am using the 2016 version. Thanks for the help!
