I'm doing static analysis. I have already set up all the prerequisites, preprocessors such as material addition, sectioning, defining boundary conditions, and displacement. However, I'm not getting the results. Please suggest anything.

I am currently reading this [paper by Noid et. al.](https://doi.org/10.1063/1.2938860) on the rigorous bridge between atomistic and coarse-grained simulations.
In the paper, he defined a linear map from the atomistic coordinates and momenta $$\mathbf{r}^n, \mathbf{p}^n$$ to the coarse-grained...
Hello everybody at the forum
I'm from Ukraine, I have Chemistry degree, and last year I began to self studying Quantum Mechanics.
I'm reading this article:
R. Garcia, A. Zozulya, and J. Stickney, “MATLAB codes for teaching quantum physics: Part 1,” [Online]. Available...
. I should preface by saying I'm a geologist not a physicist... Gotta say I usually avoid people who talk about the simulation stuff but I just saw a Tedx by George Smoot and it wound me up...
Anyway, the simulation hypothesis seems to me, and most other scientists to basically be a bit of a...
I'm making a custom wrench for personal use. For fun, I'd like to run an FEA and see if the wrench will fail. Below is a similar wrench. 100ft-lbs are applied with a torque wrench to the square socket. Where do I fix and apply the load? Should it be a torque or a force? I'm doing the FEA in...
Hi. I have a collection of points in 3D space. I'm using MATLAB to find all pairs of points within a certain range from one another. Right now I'm using rangesearch(X,X,r), where X is the collection of points and r is the range.
These points are the locations of atoms and I am attempting to...
Good day,
I am working on physics based neural networks and I am investigating the role of integrating physics based loss function on the network's training.
So I am looking for physics based simulation for data generation (online tools) to generate data from experiments.
I know I may...

v = 17 m/s
a = 1.5 m/s2
η (transmission efficiency) = 0.85
rwheel = 0.35 m
Fdrag = 100 N
Ffriction = 260 N

I mentioned this just last night and a great article in Sci American was posted this morning. So what do you think, are we living in the matrix? I say no, however I have no problem viewing DNA as a...
Hi guys!
I do have a problem in ansys maxwell simulation of a generator. The moving torque (which represents electromagnetic torque) fluctuates around zero which is not correct. Induced Voltages are ok. How can I fix this problem?
Hello everone,
I have recently come across the need of a strong constant magnetic field while being limited in space. The field needs to be unidirectional and up until now was generated by two magnets (12x12x12mm N48). Then I came across Halbach arrays and their potentially stronger magnetic...
Hello, I am looking for something to simulate/visualize simple particles and classical physics equations, preferably moving in real time

So this what I found out: One cycle takes less coordinate time, and less proper time according to the lower mirror when the clock accelerates. Proper time per one cycle does not seem to get larger with more cycles, although coordinate time per one cycle does get larger.
So what do you think...
I'm currently programming lots of physics simulators in DHTML, and my next step would be simulating a perfect gas behavior at a molecular point of view, bouncing inside of an HTML canvas.
For this reason, I came across "Maxwell-Boltzmann's law of distribution"(for speed, which I only studied...
The program begins by prompting the user to input the initial angle and speed. Once these values have been input, the program calculates the initial velocity components for the asteroid in two dimensions.
printf("Input an initial angle from 10 to 80 degrees\n");
scanf("%f", &theta)...
To simulate the trayectories of solar systems around a black hole (i.e. a galaxy) I have 3 classes in C++: cSystem, cBlackHole and cGalaxy. cSystem assigns initial values of position, velocity, etc to a solar system. cBlackHole does the same but just for the black hole. And cGalaxy mixes...
Hi,
First off, full disclosure as mentioned in the title, I am not an engineer, but I'm working on an engineering project without the required base knowledge.
I'm a professional pilot that also likes to fly flight simulators for fun (mostly military planes, because I'm not allowed to fly...
Hi all!
Like everyone else, our university physics department is prepping for online labs. We are utilizing great simulations from several sites, check them out below if you haven't already. We are able to rewrite many of our labs 1:1 conversion to online!

how would I go about creating this formula on MATLAB to apply it on an image? My guess is that I need to create the equation and then multiply it to the image I need such as:

Hello,
I have faced a weird problem and would really appreciate any comments. Assume a 2D model e.g. an axisymmetric model, meshed with quad, linear, and reduced integration elements.
As you now if a model contains contact, we will get "CSHEAR1" and "CSHEAR2" in outputs. Assuming that the...
Dear forumers,
I have two high performance AC feedthrough capacitors (47nF, 100A, class Y2, DC-60Hz) which I want to either combine with a general purpose EMC line filter, or build a custom one to filter the mains from of about 100khz to as high as possible (for shielding purposes).
I can see...
I don't understand how to use output from an NPT molecular dynamics simulation to compute a thermodynamic derivative.
I need to compute this (where "d" is a partial derivative, "T" is a subscript that means, "at constant temperature," and "E" is internal energy):

Hello friends,
I am studying an article on impedance matching which states about matching a resistance of 52 ohms with 2k ohm. It is accomplished by adding an inductance of XL= 318 ohms in series with the 52 ohm resistor yielding a parallel equivalent of 328ohm as reactance and 2k ohm as my...
Hello PF,
I need some guide points to help me formulate a project idea on the topic of optical fibers.
Namely, the professor suggested I should look for topics on modeling of optical fibers, analysis of different optical fibers, characteristics etc. and to work in a simulator, or perform a...
There is a new paper on a MOND simulation, and the participating institutes provide some credence.

As I understood it, they have tested mainly against disk galaxies. However, shouldn't it be tested against ring, ellipse galaxies and nebulas , too?
And a more...

I am working on simulating the movement of small spherical objects under the influence of drag and a number of other forces that, at least for now, don't depend on the object's velocity.
Normally I would sum up all these forces, including drag, to ##F_\Sigma## and update the object's speed...

can an experiment with cosmic rays prove or disprove the hypothesis of simulation?
From the point of view of science and physics, is the simulation hypothesis true? What is the scientific refutation of this hypothesis? What do physicists say about this?

If the simulation hypothesis is really correct, then how will the touch occur (the person touches the other person)? How will the whole process go? In modern physics, it is simply the interaction of atoms.
I am trying to make a DAC R-2R ladder with CD4040B counter. Output should be a staircase but it is just a straight line in my simulation. I am probably doing something wrong as I am not that experienced with Spice so I would appreciate any help. I tried it without counter(just attached four...
