Hello, I am currently working on a paper that reqires me to simulate a renewable energy grid with machine learning. I'd be grateful if anyone with experience on this can give a few suggestion as to which software to use for this task. Thanks in advance.

I am trying to design a simple homemade PV solar simulator. I have picked metal-halide lamps as my light source. If the PV panel has an area of 1m^2 and I wanted to achieve spatial uniformity across the irradiated surface with an irradiance of 1000 W/m^2, how do I go about selecting what...

Hello! Is there any good free ray tracing simulator? I just want to simulate the behavior of a Gaussian beam in a simple bow tie cavity. Thank you!

A while ago I started writing a quantum computer simulator in order to learn more about quantum computing. It certainly has helped me. The simulator is written in Python and the development was done on a Raspberry Pi 4. It has also been tested on a pc. In order to see it do something useful I...

comsol/ansys seem to do the job, but they are expensive I was looking for something like houdini (cg), but with actual nodes or click and define gui that provide accurate simulation (and code, but it doesn't force you to use it, unless you don't need to do something really specific) I've tried...

Summary:: So I'm trying to get more advanced with the lmc simulator, https://www.101computing.net/LMC/ But it's kind of hard to understand and keep track when it gets long. Provide an LMC program that will provide a value in three digits ten's complement. The program will take two inputs, a...

Is there any software/simulator of point charges/conductors? Preferably with features enabling dynamics of charges.

There are plenty of physics apps around already but most seem to just be words and pictures. I haven't found many that offer good simulators for proper textbook physics. So I made one. Pure Physicist - Google Play The underlying physics 'engine' uses the as yet incomplete University Physics...

I'm considering making a Natural Selection Simulator (possibly in Java). I've always been fascinated with the idea that so many traits can evolve independently of each other in the same population (even little things like tufted ears and loss of tail, etc.) and I want to see it in action. Like...

Practice your skills at docking Dragon with the ISS. Could be a lot more stressful in the real thing.https://iss-sim.spacex.com/

Hiya Hiya. I'm trying to build a solar system simulator for research purposes, and this does not seem to be all that easy. As in, my firsts tests have the moon shooting out of the solar system... I was wondering if you folks could offer some guidance. So, since it's for research, accuracy is...

KSP was one of the most famous science games as it simulates a complete space program, as well as physics such as aerodynamics and orbital mechanics. Such science focused games are rare, and something favourable amongst nerds. To make it even better, it is easy to modify the game and add almost...

Hello, I am loking for some simulator of the solar system where the movement of the planets is represented. I´'m interested in seeing the central force and linear velocity vectors.

Is it possible to calculate with precision the orbits of the Earth, Moon and Sun with general relativity instead of Newtonian Physics? How would this work? Would the software have to record past positions of each body and have the Earth be attracted to the old sun's position 8 minutes ago...

< Mentor Note -- thread moved to HH from the technical forums, so no HH Template is shown > a) Using the Yenka (or similar) simulator, you are required to build an RS flip-flop using 2 NAND gates, switches, LEDs and 330Ω resistors. Test the circuit and prove its correct operation against the...

Code: https://pastebin.com/5LajNBpj So I was messing with VPython, trying to create an Earth-Moon System. I got the actual gravity to work, and can create some nice ellipical orbits. However I run into trouble trying to make the actual (almost) circular orbit of the moon. I know that the...

Hi, I am interested in simulating the vacuum field equations, but solving a full boundary value problem rather than the initial value problem. i.e. I might have boundary conditions in all spatial and temporal extents/extremes, rather than just an initial 3D surface. Does anyone know any free...

I'm looking for a gyroscope simulator to see how a gyroscope would react in different situations and forces put on it. I have had an idea in my head for weeks now. It's starting to drive me a little crazy bouncing around in my head. I would like to see if the concept would work before I try...

Hello, I have an engineering project idea I hopefully would like to enter into a big science fair. I will need a physics Simulator that can show the effect of differing amounts of forces on 2 things joined by an electromagnet. Preferably free/open source or has a free student licence. If there...

Hello. What is the best quantum simulator till now? We could select two categories: a) Best full simulator able to solve the equations describing a system in 3D and watching its temporal evolution. b) Best digital simulator, algorithm analyzer. For the second options I have some candidates...

Hi, I'm developing a very simple solar system simulator for educational purpose. I had taken from wikipedia mass, velocity of planet and applied universal gravitation formula and applied to all celestial corps. It works well, but when I add the moon... the moon is like a planet, rotating around...

I recently put together a simple 2D gravity simulator and I'd like to get some feedback or suggestions you may have for future updates. I'm planning to make a 3D version and improve the animation (framerate, realism, etc). This first simulation includes the Sun, Mercury, Venus, Earth, and Mars...

I've made a fluid flow simulator, for anyone interested in fluid dynamics. The simulator models some basic flows which I learned on a 2nd year fluid dynamics course. It doesn't include viscosity, density or whatever else (hence for example the flow past a sphere in the simulator is a perfect...

Is there an online simulator which can be used to visualize the double slit interference? I know this can be done via equations, but as I am working with my kids on this, I prefer visual and want to add variations of different polarizers before each slit. If no simulator available, any...

Hello Everyone. Thank you for reading this. :smile: I have a made a motion simulator pneumatically controlled. It is a bowl held by a stationary cradle with air cylinders tilting the bowl left,right, forwards and backwards. The software to control the cylinders is giving me fits. I am...

Recently I have been working on a gravity simulator using JavaScript and HTML Canvas I know that is not the most practical method but it fits my current skill set at the moment I have worked out the basics but due to my lack of experience in coding I was simply looking for people who better...

Not to be confused with the full 3/4D one that I was plugging a while ago . . . this HTML5 canvas/JavaScript page was inspired by an old visual aid (requires Java plugin) that I found lacking in several areas. The improvements that I have made include: Handles spinning black holes, with...

(A follow-up on this thread.) I've posted before about Quirk, the toy quantum circuit simulator I'm working on. It's improved quite a lot in the past month (e.g. resizable gates, more displays, log-scale indicators). So I figured I'd mention it again. You can play with it at...

I've been working on a quantum circuit simulator. It works in-browser; you drag-and-drop gates and it shows information about the resulting superposition / mixed state. I'm looking for feedback about it. The source code is on github, but you can play with a live version at...

Presently I am working on Underwater Acoustic Wireless Transmission. I desire to measure water parameters at the bottom of the surface of the water and then pass it to the water surface using Ultrasound. There will be a buoy at the surface which is half submerged and half floating. The floating...

All I need is a basic circuit simulator. I've got the Quite Universal Circuit simulator. It works fine as a schematic designer but not as a simulator. I want something similar to Crocodile Technology. I have used Crocodile Technology on Yenka but I don't like how you can only use it in...

I want to create a simple 2d Gravity simulator where I have a large body i.e. A circle which could be a planet or the sun. I then want to simulate small comets or asteroids traveling past it, crashing into or being pulled into orbit. I know the gravitational force formula but that seems the...

Hi everyone: I wanted to design a 2-dimensional gravity simulator as part of a larger research project. I wrote it in Python using numpy to store positions, velocities, and accelerations, and matplotlib to display the trajectories; code is available upon request. In order to solve the problem...

Homework Statement Hey, so basically I'm doing Advanced Higher Computing Science at school (It's a Scottish qualification), and I need to build an orbital simulator in VB.Net 2008 (nothing too fancy), but I'm having issues planning it all out. I'm only going to have one planet orbiting a star...

I designed a circuit for my take-home Electronics final (for which we can use Google etc.) but I can't figure out how to test it in an electronics simulator. I'm trying to use Partsim and don't know what to do about outputs/inputs. It's a BJT amplifier. The output is supposed to be on the...

Looks like my main pet GR project is about to enter something akin to maintenance mode, since it now does all I currently need it to. It's nothing earth-shattering at first glance, but is very concise (e.g. ~100 lines of Python for the simulator script) and should be easier to understand than...

Hello all, i need your help. And thank you forward for those who will. Im looking for a computer program, that would simulate physic...most important would be simulation of magnetism , gravity and mass. Simple form of what i am looking for: Make cube in 3D world, set its mass, set its material...

So, I was playing around with a couple of voltage multiplier circuits a few months ago, and while optimizing one design, I came up with a pretty neat (not to brag) way of converting a sine wave to a square wave by using transformers in a completely different way than normally. A little while...

Impact: Earth! A meteor/comet impact simulator(text only) provided by Purdue University. Lots of fun. :smile: You can smash things into the Earth varying the diameter, density, velocity, angle, land or water entry, and your distance from impact. 1 meter: very boring. happens every 1.1 year...

I am constructing a home built flight simulator and am using hydraulic motors with a arm attached to the motor spindle for movement. I need to know how much torque I would need in the motor to lift 1000 lbs. Also I need to know how fast the motor should be to move the weight 1 foot in 2 seconds...

Here is something that I've been working on for the past two weeks, it's in its early stages, although I've done a lot of work. Fair warning: this is really CPU intensive and will crush anything short of an i7. Do not open it with a handheld! http://cilium.codebuffalo.com/ Please check it out...
