Is there a complete physics simulator that I can use to do lots of things while I learn physics? For example, I just learned about barymeters. It would be very interesting to simulate one. It could be done setting up a small atmosphere filled with a gas, the glass model and the liquid. Some time...

Hi all, I recently saw a very nice diagram of the morse potential on wikipedia I am curious if anyone has any suggestions as to how this diagram was made? What software package was used? In particular how the actual morse curve was plotted.

Anyone can recommend me which software is the best for 3D drawing for piping?

Is anybody aware of a free or at least inexpensive mathematics software package which allows the calculation of linear equations involving complex numbers? Hopefully relatively easy to use.

Hello General Engineering! I'm looking for a solution that will allow me to solve an equation (F=ma) by entering any two of the three variables, and then present that solution in a way that would be worth of reports/assignments. I'm currently requesting a trial of CSC Tedds, would love to...

Hello I need to do some simulations before trying to make a real circuit. I was advised to use the free software by Linear Technology. However, it works bad. I have a circuit with a couple of operational amplifiers(op-amp). According to the first golden rule, an op-amp should keep equal...

Are you a software engineer using differential equations or more advanced math everyday to solve problems? I would like to hear about what you do--what projects do you work on? Do you consider that differential equations and advanced math skills are useful/in demand in the realm of software...

Homework Statement In the Xilinx software symbol library (student edition version 10.1), the maximum number of inputs for AND and OR gates is 9. What would you do if a 10-input AND and OR gates are needed? Draw the schematic diagrams and show the connections.Homework Equations...

Hey All, Have any of you ever worked with thermal software such as Flixo and Therm? I'm having a problem with U-Value calculations differing between the two programs, and I would really liek to get to the bottom of why. What I'm thinking: I am coming up with some ideas based on some...

Hey, I just started a course in mechanism design this semester and I was wondering if there was a free/inexpensive piece of software that would allow me to simulate/analyze simple mechanisms including linkages, joints, and such. Perhaps there might also be some sort of java applet on the web...

Hey All! Happy Monday (No one likes hearing that) I've been recently looking into the different CFD programs available, and have become somewhat overwhelmed. My purpose today is to get some opinions, reviews, or experienced guidance on which programs would be useful to look into further...

I'm using a software to generatre sine waves for my op amp circuit. I know you have to use the headphone jack to output the signal, but I don't know how I would go about connecting my headphones to my circuit. The problem is I don't know how I have to cut my headphone wire for ground and etc...

Hi all, I have this challenge and I am not a math guy. Can you recommend a software to solve this kind of problem? Apologies upfront, I am not mathematically savvy (and English is my 2nd language) and for sure there could be better ways to explain this. You have 4 variable numbers: W,X,Y,Z...
