    Different forms of the discrete Fourier Transform

    Hi I am trying to program excel to take the DFT of a signal, then bring it back to the time domain after a low pass filter. I have a code that can handle simple data for example t = [ 0, 1, 2, 3] y = [2, 3, -1, 4] So I think everything is great and so I plug in my real signal and things go off...

    Thermal Hydraulic Calculations using NS

    I know for a fact in that my main TH code does not use the NS equation in its solution. It is a momentum balance and rather than differentials we have volume averages. This leads me to my point, in some instances such an approach is not sufficient to resolve flow features that could material...

    Fears of Graduation and Life

    If you want to find a job in industry some planning has to be undertaken to frame your experiences as much as possible to a type of job. Unfortunately, a lot of HR is automated and just not having an applied degree will auto screen you out of the process because your degree is not Physics or...

    Difficulty creating a response surface

    Hi all I am struggling to create a response surface for some data I collected. I have been asked to create a response surface to get a better understanding of how the two inputs of interests affect the output. I threw together a multiple linear regreession model since it was simple but my...

    Worth investing time to learn Workbench

    At my company no one really uses it but I know ANSYS is pushing its development. I am young in my career and I am wondering if I should just focus working in standalone or focus performing analysis from the workbench platform. Do I lose anything doing CFX or something from workbench. I know for...

    Engineering A Career in Engineering Analysis vs Design

    Ok, that is good to know. I would think that a design engineer would need to do both but in my company it appears to be seperate. I have been reading of software developers trying to make the analysis process easier so it can be folded into the design process more. I personally would like to...

    Engineering A Career in Engineering Analysis vs Design

    I was hoping to get some perspective from practicing engineers on the difference of a career in design making stuff, or analysis ( performing FEA, CFD etc on designs). I am in a rotational program and have some flexiblity. I ask because it appears these are divergent choices and going down one...

    ANSYS ADPL Question

    Hi all New engineer cutting my teeth on the ADPL language I am using the HUI as a crutch and i often go to the log file to see what the program is doing and I cut and paste out of that for my macros. I have been using this for a while and my log and error files are huge how do i clear them...

    Separation of variables on 2nd order ode

    Ok re read what I wrote and my main question is not clear Why is D^2y/Dx^2 = 0 not the same as d^2y =0 dx^2 On one side u get a line on the other u get something else what is the rigorous explanation

    Separation of variables on 2nd order ode

    Hi all Quick one, if one had an equation y' = x on could simply separate the variables and integrate. Now it the equation y'' = x you would use separation of variables what drives this? Also y'' =0. Is the same as. y''dx =0 dx Why is this legal? Thanks in advance

    Career Flexibility a thing of the Past

    Thanks for the reply It stinks because being married one needs flexibility to follow the spouse. I am currently in a flow modeling group. I figured modeling multi phase flow has broad applications. Gas, any type of chemical plant etc... The problem is you read job postings and they will...

    Career Flexibility a thing of the Past

    I am just throwing this out there to fish for opinions Engineering is often advertised as a broad profession offering many opportunities. With tight labor markets where there is an over supply of job seekers is this no longer a true statement. I ask because workers must be responsive to the...

    Complexs Roots of an ODE

    Hi All I am rusty with my my math and got stumped with a straight forward question regarding vibrations and complex roots. I have a 2nd order ODE x'' +4 x' + 16 x = some forcing funciton This turns out complex roots. I go through the run around of solving this and I get a...

    Engineering Why don't more engineers/scientists go into finance

    I think you are truly blind. The only power finance has is the power is what stock people vest in it. We are one nuke bomb fest from your precious finance tools meaning nothing I am not saying science people are smarter but to pursue a career for money sake is such a waste. Why spend...

    Engineering Why don't more engineers/scientists go into finance

    I was speaking more from the engineering standpoint. Where I am 60hrs represents more of an upperbound. I have sat in labs with post docs I am well aware of their plight and its BS. Again see above, but is doing something completely unreleated for money really an answer? Again this is a...

    Pursuing a second MS immediatly after first MS

    Hi all From an admission standpoint is pursuing multiple MS in engineering frowned upon. I am currently enrolled in a NE MS program and I want to pursue an ME masters and possibly a PhD at a different institution. I was wondering if having an MS helps or hurts from an admissions standpoint.

    Engineering Why don't more engineers/scientists go into finance

    I think for some of the banking jobs need to factor in the quality of life A) you work a ton of hours B) forced scalability of expenses if you are making 500K you need to look it which cost quite a bit C) going with the flow is joining the problem D) Because of A you are a one...

    Roadblocks to burning Solid Thorium Fuel

    hmm that is intersting is there some efficency hit or something driving such behavior supposedly thorium is really cheap? In my mind if I were a reactor vendor, I would use this as a ploy to get business from india since it seems they will be major players in the industry for the...

    Masters in Mechanical or Nuclear for useful in the industry

    Hi all I am happy to announce that I have made it into the industry. Of course the learning train never stops and I will need to think about a masters. What I have noticed is that there seems to be a greater need for ME and EE in industry than NE. With that being said do you think it...

    Free radical Halogenation for heat

    Free radical Halogenation for heat

    Hi Mike thanks for your responsce I am well aware of thermo and the resulting constraints. The goal is to take that radiation (solar or UV) and have it converted to heat via the exothermic reaction. I need help figureing out how to calculate this. Can anyone assist?
