I have generated some .dat files using Fortran on a cluster. I need to use WinSCP(https://winscp.net/eng/download.php) to access files in the cluster so sometimes I just use the WinSCP to open the .dat files generated. The data can be shown regularly like this one...

I need to create some sort of animation to explain how water flows in a flow diagram under different conditions, and wonder what kind of software would be suitable for creating it? I'm keeping it very simple, like colored lines that are in some way animated to indicate how things flow and work...

This is a post sharing some easy to follow tutorials for students majoring in organic chemistry. Hope people in related needs can benefit from this resource.1, ChemDraw Magic - an advanced video lasts less than 15 minutes on drawing molecules faster. As an introduction, the presenter drew Viagra...

Would it be possible to get a 1 degree of freedom (the saddle line of the potential energy surface) potential energy curve from the inversion of Ammonia from the software Avagadro (I have just started playing with this software yesterday)? I am doing a physics paper for a graduate QM class, and...

I'd like to use a webcam and take images of the planets directly from my computer but I can't seem to find a software though that let's me adjust the exposure for the live video while it's streaming. Any suggestions? Thanks in advance

I'm currently writing a test where my students will need to add two vectors using head-to-tail addition. I don't know how to draw vectors in LaTeX and the guides I've found have been quite tedious. I also considered doing it in Microsoft Paint, but it looks terrible. Any ideas on what software...

Hello everyone. I am a 14 year old student and am truly fascinated by chemistry. As I tried various software, they all had a very complicated UI (User Interface) and confused me a lot as a younger student. After searching a lot, I decided to make my own chemistry software. This is the final...

I use this for my backyard hobby (amateur) design work; don't know how valid it is but has always seemed to be accurate. does anyone know if similar downloads for designing other antenna types beside yagi's. just want to have some fun, no specific application.

In a nutshell: is there any free software, which can take as input full description of a relatively large system (20-100 light atoms + photons), simulate its evolution over a period of time, and tell the probability of fusion over that time? If there's no such thing available, how close could...

Hi For keeping with full disclosure - I hope to use this information to determine the need for an idea I've had that would make the lives of maths/physics students easier. I have just two questions I hope you can answer... What software do you use for taking notes during lectures and...

Does anyone know a good program, even a demo for modelling how magnetic fields influence each other? I'd like to run thru some exercises with actual numbers on wjhat kind of field patterns can be made by arranging magnets of same or different strength in different configurations. I should...

I'm in the third semester of mechanical engineering and I'm taking classes on engineering statics right now. Our professor said the he will give us a preview of finite element methods at the end of the semester. Which softwares would you recommend for learning basic structural analysis? I mean...

I wonder how can scientists trust closed source programs/softwares. How can they be sure there aren't bugs that return a wrong output every now and then? Assuming they use some kind of extensive tests that figures out whether the program behaves as it should, how can they be sure that the...

For my senior project i plan on litening a vw rabbit car. 1981. Any software that i could uuse to model the care and provide great data on how i could improve the safety after i cut it up to lighten it? Thinking adding roll bars or something.

Anton Zeilinger of the University of Vienna was trying to design experiments to produce certain quantum states and wasn't having much luck doing it. "I realized I was just guessing," he said. So why not have a program do that guessing. It can try a million guesses. So he did. While the...

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...

Can anyone tell me which video editing software is used in this video. I am doing some project and i need to show the presentation but i really liked what this video has in the background. Can anyone tell me about this software or another similar software for editing. video:

I'm frustrated with several of my PCs' performance. The issue may be with their Internet connections, or with other processing issues. Is there some software package that I can run to give me a GUI window showing Internet bandwidth, memory usage, etc, to help me debug the sometimes slow...

Dear Forum, I am trying to run a random software (such as skype), there is easy to run by mouse and click on the icon on the desktop. Now, I am trying to take advance by using CMD (command prompt). I am going to type some basic command to make skype run, but I do not know how to go into any...

Hello Physics Forum patrons! I am currently in search for some software and maybe hardware to analyze and map vibration/stability for rotating cutting tools (CNC milling). Being primarily a machine programmer and product designer, I have a very minimal understanding of vibration from a physics...

Hi, is there any software that I can use for drawing a crystal structure from atoms coordinates ?

Hi everyone, I am starting the re-design of the PLC software for a preexisting Truck Crane Loader. I will receive the Weight Chart to see what the limits are and I was wondering how to exactly calculate the resulting weight on the Crane. The CRANE is already on place, it has two joints and a...

Tomorrow I embark on a new semester and this semester I have the pleasure of learning applied partial differential equations and the software of "ROOT" ROOT: https://root.cern.ch/ So I am here to solicite advice. 1. In regards to ROOT, is there anything that can set me up better for a more...

I'm drawing various fancy cubes. I'm using Octave, which is fine for generating the data but not so great on drawing cubes. (In case you're curious, I'm drawing projections of hypercubes.) Any help?

I just graduated, and one of my last classes in school was computational physics. We would write programs using C++ to simulate all sorts of physical situations, write a bunch of data to a text file, and then import that data into Mathematica, where we would use the data to create graphs...
