How to join two objects to share values but maintain the original name? Aka N-body merger Question: As the title says, I am working on an N-body simulation I found on YouTube. The current script has gravity turned off when radius is small enough. However, I’d like to join the two objects (body and otherbody) …
Something goes wrong calculating the slope of the simulation Question: In this python code we are trying to simulate the path of a frisbee that is being shot from a shooter with a certain angle (alpha0). The angle of attack should be the angle at which its being shot, minus the slope of its path. …
Why does the moon spiral towards Earth in simulation? Question: I am trying to simulate a somewhat realistic program where Earth and the moon can interact gravitationally with each other. Now the problem is that the moon keeps on spiraling towards Earth and I don’t understand why. This is my code: from math import sin,cos,sqrt,atan2,pi …
Issue with a.any() or a.all() when trying to simulate a motion using a while loop Question: I am simulating a motion and when using a while loop, I am getting the following error "The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()". The objective is to run …
Trying to compare each element location, and if the location are the same return false, otherwise return true Question: I have tried to write here a code that takes a random permutation from random_list and compares each element’s location. I do get a False and True result but not sure that my code goes through …
How can I add many datasets to a single plot in python? Question: I am wanting to plot many datasets on one plot in python. Currently, I have hardcoded 20 of the datasets for the sake of testing my plot. Here is the shortened code below: import numpy as np import matplotlib as plt N_steps …
how to calculate x and y co-ordinates when the body is moving downwards, while following elliptical equation Question: Assuming that an object is moving vertically downwards as well along Y-axis at a velocity of lets say 0.5 m/s while following the elliptical equation, major axis radius = 100 minor axis radius = 25 Body’s initial …
How to numerically compute the mass map and density map for a collection of masses? Question: Good day to everyone. I was wondering if there is any way to extract a mass map and a mass density map for a scatter plot of mass distributions. Developing the code for the mass distributions: import numpy as …
How can I use 'prange' in Cython? Question: I’m trying to solve a two-dimensional Ising model with a Monte Carlo approach. As it is slow, I used Cython to accelerate the code execution. I would like to push it even further and parallelize the Cython code. My idea is to split the two-dimensional lattice in …
How to create a good image of "pillars of creation" by "make_lupton_rgb of astropy" in astropy,python? Question: I am trying to write a code to generate an RBG image of the Pillars of Creation. For that I am using fits file corresponding to red, blue and green, and trying to use make_lupton_rbg to generate the …
