The FEMhub Online Numerical Methods Laboratory
The goal of the FEMhub online lab is to make scientific computing accessible to anyone.
No need to be a rocket scientist. No need to own a strong computer or buy expensive
software either. Everything takes place inside the web browser window. Yes, the same
browser that you use for emails or to watch YouTube movies. And yes, you can use
your favorite iPhone or iPod. The online lab is backed up with substantial computing
power of the University of Nevada, Reno, that the University gives you free of charge.
In the online lab you can edit and modify many different numerical methods, use them
for your own projects, and share with others if you like. To facilitate your endeavors,
FEMhub provides an easy access to many useful software libraries. To access the FEMhub
community with any questions or ideas, use the FEMhub mailing list
(femhub@googlegroups.com).
We'd like to hear from you!
Currently, the FEMhub online lab uses some functionality of the Sage web notebook.
How to get started with the FEMhub online lab http://nb.femhub.org/
The best way is to try out simple worksheets that explain
elementary methods of numerical analysis.
Step 1: Sign up for a new FEMhub online lab account
This is automatic and fast. Report any problems to
femhub@googlegroups.com.
Step 2: Log into the online lab. Click on "published
worksheets". Then click on any link starting with
"Num Methods", the simplest one being "Num
Methods: Taylor Polynomial".
Step 3: Click on "Edit a Copy" in the upper left corner and
wait for the browser response. Scroll down below
the first input window and click "Evaluate"(the "Evaluate"
link appears once you click into the input window). This will
load the program. Then there are two input windows
with two different ways to plot a Taylor polynomial
that are self-explanatory.
Step 4: There are multiple other worksheets whose title begins
with "Num Methods:". Try them out and give us your
feedback!
Step 5: You can try out worksheets starting with "Hermes2D:"
that allow you to solve finite element problems via
the internet. Feel free to adjust the existing worksheets
to fit your own needs. We are working on expanding the
possibilities.
