Hey guys, I'm currently enrolled in a physics 2 class, and we've just wrapped up circuit analysis and we're going over magnetism right now. I was wondering if anyone knows of good software for windows 10 that I could use to simulate circuits in addition to mechanical systems. Thanks in advance.
I have spent the last year writing a mobile finite element program for iOS called, Hapgood Simulation, and I'd like to tell you why.
I have a Ph.D. from the University of Colorado where I studied NEMS. While in school I developed a need to simulate a particular problem, namely the switching dynamics and contact physics of an electro-statically actuated switch. I first turned to ANSYS, the lesser-known Coventor, writing my own code, and finally COMSOL -- no luck.
Writing my own code I developed a strong, to say the least, professional interest in the finite element method, and began to look around at the current landscape of the industry and how it is used in our profession. As I'm sure you are all aware, FEM software is expensive!! Typically starting around 12k for a base license, which depending on the company may expire every 6 months. Some companies even charge several thousand more for you to use more than 2 processors in YOUR computer!
What does that mean? It means that current commercial companies operate using a Business-to-Business paradigm. The big players in the CAE industry charge a company/user a large sum of money annually for a few seats (licenses), which are to be used by a small number of engineers.
In my opinion, the current industry's business models are unfortunate. FEM can and should be used for every design problem/process that an engineer works on. There is no faster or cheaper method for us to develop an intimate understanding of a physical system before we spend the resources on manufacturing, testing, and design iterations (the R&D cycle).
Which brings us to Hapgood. I firmly believe that Finite Element Analysis should be as ubiquitous in our profession as the calculator. We have calculators to help us solve problems in algebra, trigonometry, calculus, and even ODES, so why not a calculator to solve problems in Physics?? This is exactly the intent of Hapgood. I want Hapgood to be used like a calculator by every engineering student, professor, and professional in the field.
Currently, Hapgood is a 2D Finite Element based simulation tool. The Beta version of Hapgood, currently in the App store, can solve static 2D/Axisymmetric problems in Linear Mechanic, Thermal stresses, and Heat Transfer.
Version 1.0 includes the ability to solve problems in: torsion, crack mechanics, fluid mechanics, mass transport, electro-magnetics, acoustics, joule-heating, joule-heating-thermal stresses, and convection-diffusion. Making Hapgood a well-rounded tool for everyday use by students, teachers, and professional engineers.
If you decide to check out Hapgood, be aware that there is a short walk-thru for the simulation of a bi-metallic beam at elevated temperature available at www.hapgoodsimulation.com/tutorials
. The tutorial should get you up and running quickly.
Feel free to email me if you have any questions or thoughts that you'd like to discuss.
Thank you for all of the constructive comments and criticism. I greatly appreciate your input. After working on something so intensely for such a long time it is easy to become near sighted, case in-point the problem with the GUI on the iPhone. The tutorial at hapgoodsimulation.com/tutorials has been revised to point to the "invisible button" that Whodiditandwhy
mentioned. I will submit a fix for that screen and other similar screens to include a simple "done" button to return you to the main screen later this week, which means that version of the app should be available by the end of next week. Again, thank you all, I've really enjoyed this discussion!
