HTML
One of the main goals of this project was to make the book
widely accessible to anyone interested in learning Modelica
at no cost. For that reason, the HTML version of the book
hosted by Xogeny is free
and will always remain so.
That being said, if you find the HTML version of the book
useful we encourage you to buy either an electronic or print
version of the book to show your appreciation.
ePub/PDF
You can purchase both ePub and PDF versions of the book in
either letter or A4 format. Once you buy the book, you will be
sent links to download the electronic versions. As new versions
of the book become available, you will be sent updated links
to the latest electronic versions.
FAQs
- Isn't this book free?
- Yes, the HTML version is free. But the other electronic
versions are not.
- What do you mean by "pay what you can"?
-
It means that I want people to learn Modelica in an
affordable way. If you are a college student, you can
read the HTML version for free or spend $5 and get the
electronic versions of the book, too. If you are a
professional engineer, I think you should be willing to
pay at least $20 for a book tied closely to your
professional activities.
-
What happens if a newer version comes out?
-
Anyone who buys the electronic version of the book is
entitled to free upgrades for life. Be sure to include
your email address and you'll be added to the mailing list
of people who receive new download links for subsequent
version. So you don't have to worry about getting stuck
with an old version.
- What kind of DRM is there on the electronic version?
-
None. I hate DRM and I don't want to waste my time
trying to prevent people from stealing the material. If
you are that desperate that you need to steal it rather
than pay $5 then go ahead. But I believe that most
technical people are inherently honest and I trust them to
pay what they think is appropriate. I hope they prove me
right.
- Wasn't this book already paid for via Kickstarter?
-
The Kickstarter project was a way to demonstrate demand
for the book and avoid taking on a big financial risk. At
the end of the day, the goal was a free HTML book on
Modelica and that was successful. But I hope to keep the
book up to date and add future chapters on advanced
topics. Those activities go beyond the scope of the
original Kickstarter project and by buying the book you
not only provide financial compensation for the effort
that was already made in creating the book but it
encourages such future work as well.
At the moment, there is no print version of the book. Our
goal is to incorporate all the feedback we receive on the
HTML version of the book before making a print version. We
want to avoid situations where the print version becomes
obsolete compared to the electronic versions.
We do plan to produce a print version. So, please subscribe
to our mailing list to
be informed when the print version becomes available.
