I'm a little outside my area of expertise here - I've used ADS to exhaustion, but now I need to simulate a MESFET I designed. Anyone have any recommendations for software? Our computer labs have quite a bit, but if there's a nice free/lite version that would be ideal. Thanks in advance.

I am looking for software to calculate flow rate, pressure drop, flow rate and temperature change in facility piping. Any suggestions?

Hello everyone! I'm looking for a software in which i could simulate physical experiments from the field of classical physics. Before you start recommending matlab, i would like the software to be, well, a bit "higher" :) What i mean by that is that is should simulate the model in 3d...

I am designing web software to interface to \LaTeX, Maxima and R. What I wanted to get feedback about is: 1) Security issues which may arise from calling Maxima and R from the web. The interface is going to be a AJAX GUI and not a raw command-line input form so I will be able to filter...

I hope this is the correct forum, I have read most of the rules and it seemed the best place for this post! I have a Chemical Engineering problem, in the design of a reactor which has a design equation which I know to be a 5th order polynomial. Deriving this from first principles takes a lot...

I've been delving a little deeper into electrical theory in terms of noise and low signal measurement as I'm working on some rather sensitive stuff and the back of my napkin calculations isn't cutting it anymore as I need to account for things like opamp input bias, voltage offset, etc. I...

When I read on a computer screen I like to use the scroll wheel on the mouse but when I do the text jumps and it is easy to loose my place when reading some text. Would it be hard to have a mouse control panel adjustment for the scroll wheel that could be set so as to allow the window to move up...

I'm currently on a Mech Eng undergrad course going into my final year. I have used a number of drawing and simulation packages. My question is, in the industrial world what is the most used piece of CAD software? I am not so good with Pro/E and so so with AutoCAD. We are learning Solidworks...

Hello, Is there any software which solves integrals STEP BY STEP? Thank you.

Hello everyone! I have recently decided that I want to pursue a career in software engineering, but the problem is that I haven’t taken many courses in it. I’ll briefly describe where I’m at now: I’m a senior physics major, and I had originally planned on doing some sort of medical physics or...

I'm currently majoring in EE, and it's my first semester and I realized the math class I am in is like so far behind what I am suppose to be in. I know EE is a GREAT job, lots of money, lots of job demand (lots of people want to hire you), and such and such, but the math and physics is extremely...

Hi Pretty simple, just what the title says, anyone know of some good drawing software for Mechanical Engineering? What I mean by drawing software is software that can make diagrams such as MOHr Strain Diags, Beam Diags, and Freebody drawings, etc.? Thanks

Hey folks, I am looking for something free to help me out here. I have experimental data that consists of the temperature and pressure of a gas over time. That is I have (T1,P1), (T2,P2),...(Tn,Pn) where n might be upward of a 500. I would like to be able to determine the specific volume...

I am a software engineer of 20 years and would love to use my skills to somehow help work on the Carbon Dioxide problem (or other problems that could help the environment). I was wondering if simulation software might be written that would allow one to model various processes that attempt to...

I am looking for math software that will fit a set of points with a cubic spline (or other technique)...then allow the user to change the shape of the curve by dragging it...and continuously fit the curve as the dragging is occurring (or fit the curve after the dragging has stopped). The point...

Hi, taking a chance here... i recently played a game. This game involved you starting out with a marble in 3d space, and u had to design a path for it to reach a finish line, with ropes/gears/what have you... i was HOOKED, but i don't remember what its called...=/ any help would be appreciated

When checking results, solving a problem, simulating a problem etc in relativity, what software do you tend to use? cheers, Jason

I am a sophomore student in Indian Institute Of Technology, doing mechanical engineering (Just introducing myself as this is my first post in this super-mesmerizing website) Well, we haven't yet started any CAD courses in college, and i will have to bunk a few classes tomorrow to attend a...

I am in my 3rd year of a physics b.s. program. I have been taking a few courses (not many) to get a computer science concentration. I have become increasingly interested in software engineering (not just programming), so I'm looking into how hard that is going to be with a physics degree...

currently, I'm be studying on improving fire tube boiler's combustion efficiency. so, i need a software which is applicable to the title above in order to prove my calculation according to the formula. can u tell me what software can be used?

Hi I have a relatively general question. How does a computer software/program (ex. like a printer driver) cause mechanical motion/action (ex. actual printing by the printer)? Another example would be software controlled robots, an input into a computer software causes robots to perform...

I currently use one note, but the drawing functions doesn't even include curves. So basically a big fail. Is there any good software for this?

Hello everyone, I am a software engineer and know very little about lenses but am trying to learn. I am confused about the differences between convex-convex and plano-convex and how to decide how to design an actual plastic lens for a real world application. Here is an example (not real...

I need something that I can use to draw a few simple 2D images, that don't have to look pretty. I really mean "draw" (with the mouse) and not generate from a formula, and a minimum requirement is that the program can at least let me try to draw a smooth curve with the mouse and then smooth it...

So, when I'm looking at the college I'm pretty sure I want to go to, they offer CS. At some colleges, I've noticed that they have CS AND software engineering. So, is there a difference?

do you guys know any free mathematical software that can help me find the area under a graph which can't be intergarted using just a level skills. i already checked autograph but it kinda sucks and i looked other forums but didnt find a thing about this.

Hello! I asked my question in "Computer / Software" tread, but no one was able to help me, so I`l try asking here.. I am in need for software where I could design some system of objects (electro motors, moving parts, custom modeled parts etc. ) with whom I could see "real life" simulation of...

This needed a separate thread. Here is an APL example where it's all done with no interation using N by N matrices in the intermediate propagation of data. Note, code flow in APL statements is right to left. The []IO<-0 sets the "index origin" to zero so a list of numbers and indexing...

How does computer software plot magnetic field lines where the density of lines represent flux density? How does the software know which points to start plotting from in order to come out with a true representation?
