r/Simulate Mission Statement VIDEO OF STATEMENT

This sub-reddit is dedicated to keeping track of any links, sources, people and illustrations which describe methods or projects that simulate the physical world or the human mind. Simulation describes a broad spectrum of phenomenon translated into a computational approximation; computer simulation is the Church-Turing principle applied to reality.

Simulation encapsulates all of science and history, and requires cutting edge technology; as a species, simulation is of monumental importance for improving our own world and Nick Bostrom is correct, spawning new universes.

Original inspiration for this sub started with an interest in procedural generation applied to 4X gaming. We have an ongoing project which aims to have a Web3D render engine and a modular simulation API framework.

From this point on, we will use /r/Simulate as an interest focused link share, and the below project resources as our simulation & game planning location:

Resources for simulation games, like DF

Hey, I’m about to finish the second year of my CS bachelor, and I am interested in starting a summer project. Games like Rimworld and Dwarf fortress really interest me, games that feel alive, like they could go on without you in a sense. I would love to try my hand at making a very VERY simplified version of DF (as I know how complex it is) with my own spin on it. However I am unsure of where to begin.

I have some experience with C and C++, which I think could do the job along with something like SDL for simple graphics like DF. I would prefer only using C as I am not a big fan of C++. Would this be a good start?

And if anyone has any experience with this genre of gamedev, could you point me in these direction of some useful resources like books or websites. If you have any tips or suggestions i would love to hear them as well!

Series on simulating molecular water with gpu acceleration

Hi! I am making a series on simulating molecular water, using the Julia programming language. My background is that of computational research in micromagnetics, so I thought this molecular dynamics stuff would be a fun new thing to try. I don't have a whole lot of youtube-presenting experience as you can maybe observe, but I hope any of you might enjoy this/find this interesting: https://www.youtube.com/watch?v=FxLs_ifu23U&list=PLiz3ZHIQEYQUqKWSpNreEeHvqUFvsHvo_

Modeling a PLD Setup: Suggestions for (Python-)Libraries or Tools?

Hello Everyone,

im working on a Pulsed Laser Deposition setup. In this setup, a laser shoots (at a variable rate) on a target material (the rectangle shaped object at the bottom), that is then deposited (in some kind of profile, as indicated by the transparent cone) on the material on the opposite side of the target. The material on which i deposit is a tape wound around a cylinder, which is rotating at a variable rate.

In addition, the position of the target can be moved along the cylinders main axis.

The image below was created in Fusion360, to illustrate the system. Now I would like to write a code that simulates my deposition process, to predict how much material was deposited at which point of the tape.

Can someone suggest me some good starting points? Do you know libraries or programs (other programming languages are okay) suitable for this job? While I could try programming the system, I am seeking for a way to visualize the process at the same time to have a visual feedback of my calculations, as the parameters may be changed programatically during runtime.

Best Regards

MrHTSC

Best workflow simulation tool

I am trying to decide learning either Simul8 or Simio for conducting a simulation on systems. Which one of these 2 softwares will be the least demanding on my laptop.

Any other alternatives that are easy to learn and translate ideas quicker and get high level data to explore whether certain projects are worth considering for further analysis.

Particle simulation - not finding brownian motion for the simplest case

I've created code in python to simulate particles and first the goal was to obtain brownian motion, meaning a plot of mean square displacement versus time gives a straight line. However I'm getting an exponent of 1.07 rather than 1.00. Meaning not straight. It is consistent even when I increase run time, change particle size, space size, velocity. I'm not sure what it could be, because when I look at a visualization of my simulation the particles behave completely normal. Any ideas?

Stock levels in Simul8

Does anyone know how to simulate stock levels in Simul8? I'm essentially trying to model the kitchen of a fast food outlet. I want to set a stock level for fries. When this level falls below a certain limit, I want a new activity 'peeling and cutting potatoes' to become active. In this circumstance I also need one member of staff to switch from a floating resource to a dedicated resource for this activity, until the stock level is replenished to a required threshold. Any help would be much appreciated.

ARENA HELP

Ok so to explain my sim it’s for manufacturing, so multiple entities(parts) come in and all finish at one robot, I figured out how to give them different process times, however I need to order them very specifically in the queue. For example I want this robot to run: part 1, part 1, part 3, part 3, part 1, part 2, part 2. Is there any way for me to order the process in this way?

Trouble Downloading Arena

This is on Windows 10. When I attempt to download and install the latest version, I am told that I already have version 6.00.00 installed. This is not the case. I have never used this software before. When it then proceeds to ask me to remove the existing version in order to install the new one, it is unable to do so. The installer can only remove installed items, and because the old version was never actually downloaded, it is unable to do so. All attempts to install get stuck in this loop, including deleting the entire install package and redownloading. Anyone got any ideas of what might be going on?

Exploring siml.ai – Any Experiences or Insights?

Hi guys.

I found this project siml.ai on X. As a physics student, I use mostly my MacBook and my iPad, and I need to run simulations for classes and research. They say it’s web-based, so it’s nice for me because I don’t have any powerful GPU and I don’t have much time for setting up cloud computing like AWS. Although I would like to learn more about how it works and if it really works and it’s not just another AI buzz crap. What exactly is this NVIDIA Modulus and if it’s web-based, do they use some cloud computing? If yes and I don’t need to setup any AWS, then it’s nice for me as a user. But still there is a question if it’s really useful in terms of reliable results. I don't know much about this NVIDIA Modulus. I have seen some people in the industry, but also at our university, mostly engineers, use Siemens solvers (Siemens STAR-CCM+), and it has pretty useful and reliable results. Have you tried this siml.ai? I thought about trying the free trial.

Batching in Simio

I have used Arena extensively and am currently learning Simio. I wanted to know how to batch in Simio.

For ex. If I take a manufacturing process where 10 pieces are loaded in a basket and is dipped in paint, in arena I will use the batch module with a temporary batch of 10 and process it.

In Simio, I have the combiner option, but it requires 2 inputs a parent and a member. How can I have just 1 input which batches 10 pieces. I tried connecting the output from the previous server to both the inputs of the combiner, but that is not the right way to model it.
