@StatGuy2000 said in another topic this part quoted here: The name of the topic was "From math PhD to space industry-possible?" The listing of what was suggested for the PhD student to learn looks like a large amount. Four different programming languages, although he did not say to what level...

For a 2D problem with unknown displacements u(x,y) and v(x,y), is it allowed to give such a set of BCs u(0,y)=1 and vy(0,y)=0, the former being a displacement BC, the latter being a force BC (vy is the y strain)? How is this implemented in FEA software?

Hello everyone, I am from India.I completed my Bachelors in Engineering, ECE to specific from a very average Indian college in year 2006 with many backlogs and year gaps. Since then I have been working in the IT industry.I have a undergraduate percentage of 56%, using...

Here are two examples: 1. Microsoft Excel. If you buy the newest version of Microsoft Office, it is able to open and read all files that were created with the older versions of Microsoft Office. Let's say that I have an older version of Microsoft Excel and I create some files with it. Later...

I would like to simulate both double-slit and Mach-Zehnder interference, with some other common optical components such as lenses, beam splitters, mirrors, and wave plates. Is there something online for this or a program that can be downloaded and run on either Linux or Windows? Thanks, Erik

I am hoping this forum may be a good page for this question. Not sure where else to post. I have been asked if I can write a user GUI to control a system that we build--the system is made with the fairly common electronics board designs and PIC MPs and presently is controlled from a...

Hi, The issue of granting/using remote access to a computer came about today re the topic of RDP ( Remote Desk Protocol) and Team Viewer. Obviously some security measures are needed to prevent 3rd party access . Any comments on the level of security needed for a stand alone PC? How about for add...

Hi all In my country, and with the pandemic aggravating affairs, an academic career seems unlikely for me at the moment. It's what I have been preparing for, I finished my PhD and started looking into post doc positions nearby, but no luck so far. So people advised me to try becoming a software...

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

Just wanted to give a shoutout to SchemDraw, a FOSS circuit schematic drawing package for Jupyter(Python), made by a PhD at Sandia Labs. It's purely drawing, not simulation of any kind, but given Python's numeric and symbolic superpowers it's easy enough to bolt-on that functionality. If...

What do people use for drawing molecules (in a digital manner)? I would like to make space filling type models as well as letters representing the atoms connected by lines at different angles. The second kind I could make with ad drawing program, but there's got to be a better way.

Is there any software available to calculate cross section using .cif file?

Hi there, Last June 2019 I graduated with a First class honors in Theoretical physics from one of the Top Unis in the UK. Then I started working for a company (of good prestige) as a software engineer full time. However, a few months in, I decided to apply for Masters and start a side project...

Hi PF! I'm using Salome, an opensource software to build .stl files. I'm trying to cut a triangular cylinder from a rectangular cylinder. Here's how I build the two cylinders: I'm building the rectangular cylinder through the hot key "build a box" toggle. To build the triangular cylinder, I...

Hello, I wanted to confirm a suspicion with how the Aimpoint optics work, but to do that I need to do some ray diagrams. I only ever did them with simple convex, concave, and spherical systems while at college. From what I already know of how reflex sights work, the LED is placed at the focal...

I only have access to mathematica currently. Regarding specifically its power to solve integrals, is it more unable to solve integrals than others like Maple? If the answer is yes, then I will move to purchase Maple.

Someone told me to use parametric equations to find symmetries first but are there other methods to sketch this graph? How do you think

Hi guys :oldsmile: Several years ago I installed in my computer software „Realtek High Definition Audio“. The option “Karaoke” (with red line) enabled the sound/music to be played with imaginary/seeming high or low rate (however, the actual rate remained the same), this I liked very much. But...
