Best language for Molecular Dynamics Simulator, to be run in production. (Python+Numpy?)

I need to build a heavy duty molecular dynamics simulator. I am wondering if python+numpy is a good choice. This will be used in production, so I wanted to start with a good language. I am wondering if I should rather start with a functional…

Looping over rows of a data frame to simulate

This is more of a programing in R question than any concept question. I tried but my lack of expertise in R is frustrating me: I have a dataframe df with columns ID, xR01, xR02, nR01, nR02, xRsum, and I want to use hypergeometric function to…

Average time to hit a given line on 2D random walk on a unit grid

I am trying to simulate the following problem: Given a 2D random walk (in a lattice grid) starting from the origin what is the average waiting time to hit the line y=1-x import numpy as np from tqdm import tqdm N=5*10**3 results=[] for _ in…

Why should I use normalised units in numerical integration?

I was simulating the solar system (Sun, Earth and Moon). When I first started working on the project, I used the base units: meters for distance, seconds for time, and metres per second for velocity. Because I was dealing with the solar system, the…

Combine multiple FMUs into one

I have a pandapower network and at some buses I have included batteries and photovoltaics as FMUs. Right now I have a master algorithm that creates the connections between the inputs and the outputs of the different FMUs and it runs the…

Is it possible to simulate a blocked dialog like 'window.confirm()'?

I want to simulate a block dialog like window.alert(), window.confirm(), or window.prompt() with DIV+JavaScript. It seems easy using a callback function. But I want to block the process while the confirm dialog is shown. That is to say, I want to…

How to simulate first passage time probability in python for a random walk?

I have a 2D random walk where the particles have equal probabilities to move to the left, right, up, down or stay in the same position. I generate a random number from to 1 to 5 to decide in which direction the particle will move. The particle will…

Algorithm for calculation of future good amounts with complex production lines

This is a very long post, but only the first half is really relevant.  The second half describes only what I have tried to solve it, but what seemed to me too inefficient (it can perhaps help to get the idea of what I want). The relevant part ends…

Weird behaivour when trying to simulate gravity

I'm trying to simulate Newtonian gravity with C++ and GLM. I'm using GLM vectors and this equation I found on Wikipedia I translated this into code: const static double g_const = 6.67430E-11; void gravitate(object& obj1,object& obj2) { glm::vec2…

Force calculation for magnetic pendulum and numerical integration

I've been working on a simulation of a magnetic pendulum (Magnetic Pendulum for reference). Now, I have a question concerning how you calculate the forces/acceleration: In examples you find online of the magnetic pendulum (such as the one provided…

Availability data

I'm creating a simulator for a large scale P2P-system. In order to make the simulations as good as possible I would like to use data from the real world. I'd like to use this data to simulate each node's behavior (primarily it's availability). Is…

Can I use the output one GLSL shader frame as input to the next?

I'd like to use a single bitmap to store the state of a 2D dynamical system which evolves over time according to some rules. Think of it as a grayscale image where the brightness of each pixel represents the temperature of each point on a…

Proper nuclear fission simulation in C++

I'm trying to simulate atomic fission in C++. Fissile nuclides have known probabilities to produce certain atomic numbers and mass numbers as fission products, such distributions are called fission products yield. I know mass product and atomic…
