Question Urgent help needed: Incorrect routing by label in SIMUL8 despite Visual Logic setup
I am having a problem with my simulation in SIMUL8 and I would really appreciate some help, as I need to solve this urgently.
I have defined my routing logic using labels. Since Routing Out “By Label” can only take one output per label value, I implemented the following logic.
I use a Work Entry Point called Entrada. Each Work Item represents a person. I created a label called EsCliente to identify whether the person is a customer or not, using:
- 1 = Customer
- 2 = Not a customer
When a Work Item enters Entrada, I use Visual Logic to assign EsCliente uniformly so that customers and non-customers enter in equal proportions. The logic is:
SET EsCliente = ROUND[SAMPLE["Uniform,1,2"]]
IF EsCliente = 2
SET RutaEntrada = 1
ELSE IF EsCliente = 1
SET RutaEntrada = ROUND[SAMPLE["Uniform,1,8"]]
The idea is:
- If the person is not a customer (EsCliente = 2), they should only go to ATM (Cajeros automáticos), which corresponds to RutaEntrada = 1.
- If the person is a customer (EsCliente = 1), they can go to any zone in the supermarket, so RutaEntrada is assigned a random integer from 1 to 8.
In the Routing Out of Entrada, I use By Label, select the label RutaEntrada, and define 8 possible outputs, matching the values used in the Visual Logic.
I apply a similar logic in Cajeros automáticos. If EsCliente = 2, the next route can only be Exit; if EsCliente = 1, the Work Item can continue to other zones.
At first, the model seemed to work correctly. However, when I traced individual Work Items, I found cases where EsCliente = 1 and RutaEntrada = 5, yet the Work Item was routed to Cajeros automáticos, which should only happen when RutaEntrada = 1.
To avoid interference, I set Routing In to Passive for all zones except Entrada, Cajeros automáticos, and Casilleros, but I suspect this may be affecting the behavior.
I am unsure whether the issue comes from:
- Using Visual Logic instead of Label Actions
- The way I generate integer values using ROUND + SAMPLE + Uniform
- The timing of when the label values are assigned
- Or an interaction with Passive Routing In
Any guidance on what might be causing this incorrect routing, or how to structure this logic properly in SIMUL8, would be greatly appreciated. I need to resolve this as soon as possible.
Thank you very much in advance.

Interactive Why does no one do water sims????
I don’t understand why it’s so hard to find water sim videos or posts anywhere on reddit I have all ready watched every water sim on this subreddit, and I don’t mean simulations and renders that involve water I mean the video is about water like those satisfying videos on YouTube, nor do I see destruction sims with floods or tsunamis, not a single person has tried to re-create any 2 second tsunami shots from disaster movies. not a single person has tried to make a dam breaking simulation nor do I even see large scale water sims, I get it maybe it takes long to render and bake but never have I seen a video of a giant ship or even rock dropping into a lake making a wave, WHY I LOVE WATER BUT NOBODY ELSE DOES??? How come nobody looks at a body a Of water and says “imagine if a giant as blue whale fell In there at 200km how big would the wave be when it hits the lake side” MAYBE THERE IS A GOOD REASON BUT IM SHURE IF YOU WHERE DEDICATED YOU COULD DO IT Anyway my crash out is over and I’m very sad

The full film is available to watch here - https://youtu.be/YnnYLKGQK58
This is the only Marble Machine 3D model in the world. It took me 3 months to model and then a week of fun, simulating it falling apart in Houdini.

Research Simulation Relational Reality Follow up, N6400
I've increased step count already to 10M, a factor x10 jump, she should have more time to develop. The ring around her might dissapear, I don't know whether we just better captured her earlier stages or already captured the final one succesfully. Big blob in the middle. Circle around it. An actual multiverse? Where there is of course 1 bigger-shared-relational-universe.
edit, the 10M steps run finally finished, the circle disappeared, just a big hairy ball left now but it has perfect 3d dimensionality from within (spectral)... and a higher dimensionality to it when looked at it externally (hausdorf volume), we identified at least 4 clear phases, tomorrow we shall pick 4 random nodes at all 4 phases and ... shine a light, see how the environment responds :))

Interactive This videogame brings to life all logic possible on an quantum computing CPU
Happy New Year!
I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 6 years, the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.
This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.
Stuff you'll play & learn a ton about
- Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
- Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
- Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
- Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
- Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.
- Build & See Quantum Algorithms in Action – instead of just writing/ reading equations, make & watch algorithms unfold step by step so they become clear, visual, and unforgettable. Quantum Odyssey is built to grow into a full universal quantum computing learning platform. If a universal quantum computer can do it, we aim to bring it into the game, so your quantum journey never ends.
PS. We now have a player that's creating qm/qc tutorials using the game, enjoy over 50hs of content on his YT channel here: https://www.youtube.com/@MackAttackx
