Hello!
Problem #1: For some reason my model's flow item's "so.subnodes" do not show up. Just the first item that was created shows up. What could be the reason behind this?
Problem #2: Why does the flow item referred here as "product"? Does that create any issue?
Hey so I am sorry I did not explain my issue properly earlier.
At station 2 on the conveyor belt, it is supposed to produce two items (check the circled array) but it only produces 1 item. I believe every station where there are more than one items that need to be created at "Create Object" it only produces one of them I think.
@Jason Lightfoot any idea why this happens? Tagging you since you were a huge help for this model.

The items on the conveyor are nested inside each other. You are only looking at the direct subnodes of the conveyor, which is only item called "Product".
You could write a user command that recursively adds all levels of subnodes to an array. (In the example below, the start node (conveyor) is also part of the array at the first position)
treenode curNode = param(1);
Array allNodes = []; for(int i = 1; i <= curNode.subnodes.length; i++) { allNodes = nestedSubnodesToArray(curNode.subnodes[i]).as(Array); } allNodes.unshift(curNode); return allNodes;
Felix,
Should I write this command in the same user command? or a different one?
Also, are "nestedSubnodesToArray" and "unshift" commands found at Command Reference website of FlexSim? Because I could not find them there.
"Unshift" is a method connected to the array class. It adds an element to the start of an array.
"nestedSubnodesToArray" is the name I chose for the user command. As I said, it works recursively, by calling itself, to find all subnodes under a given starting node.
Attached is an example model. Run the simulation to generate some items in the queue, then try the command in the script console.
So i played with it and it returns the array of all nodes like discussed. Here is what i want to understand since I am a newbie at this.
Q1. How does the script know that i am referring the nodes? Is it through the treenode param? What if i had multiple sources, in that case how will the script know which treenode am I referring to?
Q2. The for loop stops when it reaches to Box. Is it because the box does not have anymore subnode?
Q3. When i changed the quantity to 3 at Source, your script only runs for the 1st token and not for the other two tokens that are created later. Why is that?
Hello @Abhay Bajpai,
In the Parts array the second index contains a string that will be used to select the flow item that will be created. It is not able to because the string does not end up matching anything in the flow item bin because there is a 1 at the end of it
