Pretty much every professor in my physics department has said that it when it comes to American physics graduate school, it is harder to get in as a theory student than as an experimentalist. Do graduate programs consider computational physics, numerical material sciences, etc... essentially...

There are a few threads in this forum about CFD, but I thought I'd establish one for a general discussion of CFD methods and applications and tie it in with others as appropriate. In the December '07 issue of Aerospace America in the Aerospace Sciences section is a short article on the recent...

If i have a program, how can i find the computational complexity? is there some other program i can run in the background?

Hi, I'm interested in pursuing a career in computational science and numerical computing and so on. I'm looking for some fairly general advice on how to direct my studies. I started learning programming in java, which I very much prefer to program in these days, having had some exposure to...

Ok here's the scoop. I'm fresh out of high school and starting my first year at college. Before I get too deep into one particular area and get stuck I was hoping I could get some help here and some useful advice from you guys. Bottomline: I love math and I love physics and as of right now I...

Hi, hope this is the right area for this. I'm currently doing preliminary research for my computer science dissertation. I'm thinking of doing something in CFD...either representing the effects of wind on fur, or simulating a river flowing. Most CFD 'googles' have resulted in me finding...

How is the job security, and/or salary for a student studying computational science?

I am in need of a project that needs to be based around "computational physics" firstly, can someone define "computational physics" for me? My best understanding is that it's the physics that have more to do with math and equations versus physical exploitations. secondly, does anyone have...

On the surface, Computational Physics appeals to me a lot. I'm very interested in physics, computer programming, creating simulations of mechanical systems, and games programming. However, I don't really know what Computational Physics is. What would I learn? How attractive would I be to...

Hi there - I'm new to the forum... I need help! I have to research an interesting problem in the topic of fluids and fields which can be solved/investigated through Computational methods. To do this we're supposed to use google - but it's just not coming up with anything. Any suggestions...

Hi, First I hope it is okay to post the problem here(?). I have some general questions regarding the use of software for chemistry simulations - my questions are more fundamental than software specific. I would like to simulate a chemical reaction - so I should be searching for the saddle...

I would like to start a discussion that summarizes the main computational challenges regarding Turing machines, so my question is: what are the current computational problems which are widely recognized do not have any efficient solution in a probabilistic turing machine. Maybe you can answer...

Hello, I have to write a MATLAB program for a problem that utilizes a M-function. I was curious if you guys knew of any good websites that have some sample code for such problems. Also, I am somewhat familiar with programming in C++. How much does MATLAB differ from this language? Any help is...

'Schoolbook' multiplication takes O(n^2) operations. Karatsuba multiplication takes O(n^{\lg 3})\approx O(n^{1.59}) operations. The best method I know of (which is only practical for very large numbers) is O(n \log n \log\log n). Is there a known nontrivial lower bound on the complexity of...

Computational Physics can be frustrating sometimes... Just realized that my past eleven weeks of work has been entirely invalidated due to single error in my simulation inputs. Arrrg. On the upside, I think I've got the process down now, so its just a matter of rerunning everything...

M&B Journal Club: I hope this will be thread #6, if not please rename it appropriately. Date: First week of Sept 06. Topic: Computational Neuroscience Papers Papers: I will attempt to present 2(maybe 3 papers) on the topic above, all models using Neural nets. The first Paper deals with...

I will be applying to graduate school this coming winter, and I'm having difficulty deciding what field I should be directing my effort towards. My background: I have a bachelor's a physics, and my senior project was to write an N-body program that simulated galaxy collisions with the inclusion...

Are there many interesting computational physics problems out there? Are there any comet trajectories that will deviate from a standard ellipse? For some reason plotting the path of a baseball just doesn't spark my interest.

Hey, In doing a circuit simulation i want to allocate a matrix like this (c++) double S1store[3][steps+1] i get no compiling errors, but if i make steps greater then 28000 the program gives me a windows error and crashes, it runs fine on a unix system. is there a limit to the amount of...

What kind of jobs would someone focused in computational science (or more specifically comp. physics) be able to fill?

I am trying to do a QST2 calculation on two geometry optimized structures that I obtained by doing DFT calcs. The QST2 calc runs fine and finds 1 imaginary frequency resulting in a transition state that appears reasonable. However, when I pick points to the "left" and "right" of the transition...

Perhaps this isn't in the right section, although I couldn't think of a better one. If I wanted to start working on computer simulations, what language and packages should I pursue? I know the blog highlighted Python, but after a point, it has its limits. I was thinking C++ or Java, as I already...

What are some of the more practical applications, if there are any, of computational physics?
