I no longer actively maintain hedge or its computational
infrastructure. Its successor code lives here:
https://gitlab.tiker.net/inducer/grudge
Be aware though that this code is still a bit rough around the
edges. (and therefore only 'semi-public' at this point)
Best,
Andreas

Hi,
I would like to try to reproduce some of the results of this paper
http://rspb.royalsocietypublishing.org/content/470/2171/20140080
and looked at Hedge as an interesting blend between C++ and python. I
have run into some compilation problem though. I've tried many things.
My best approach so far was to follow the guidelines here:
http://wiki.tiker.net/DevEnvironmentHowto?action=show&redirect=Repo
After doing
repo init -u http://gitlab.tiker.net/inducer/akprojects.git -m hedge.xml
and exluding pycuda I got the project compiled. However, when I run an
example I get an error (see below). Looks like a simple dependency
problem. The file definitley exists in boost-numeric-bindings, but I
don't know how to tell hedge to look there.
Also I am running it all on Arch and python3 is the default one there. I
think am managing it and I don't it's related to the error but I am
mentioning it just in case.
Please let know if you have any suggestions,
Robert

Hi all,
first of all my thanks to Andreas for making Hedge code available.
I am looking for a solution to do some DG analysis in the field of solid
mechanics, and Hedge looked promising, as I am pretty accustomed to Python.
However by looking at the documentation I am not really sure if it is really
the tool for me, nor if the effort I would need to make it work as I wish
would be sensible or not.
I am interested in solid mechanics problems which have solutions with evolving
discontinuities across some subdomain, usually a surface or a line ( I am
thinking of crack propagation inside bodies).
I know there many techniques to address allow for such a feature in the
solution, so I am wondering if Hedge have some built-in support for this kind
of problems.
In case it hasn't and if you are familiar with these technique, do you think
it would be hard to modify the code to model problems like the one mentioned
above?
Thank you,

Hi.
I'm new user of this power tool, and I have a few questions.
# Can Hedge run with PyOpenCl (this is because in my research group
only have ATI's GPUs).
# When a I find a Heat template?
# Do you know about some paper that use this tool?
In my group, we research about root growth, for now in one dimension more time.
Thanks.

Hello I was wondering if there is a simple way to extract a matrix form for the RHS operator in maxwells equations. I was hoping to experiment with the IMEX-RK routine but that requires a matrix form the linear RHS operator. I found what I think may be an example of that in '[thesis-experiments.git] / 2009-11-maxwell-spectrum / max-spec.py’ but I just wanted to confirm with you that is indeed what you were doing in the build_mat function. And just for the sake of me really understanding, would you mind explaining a bit what exactly you did?
It looks like you are generating a 'unit vector’ for a given degree of freedom (if we have a column vector of length N then we iterate over N and say all entries of the column vector is 0 except for the current iteration), plugging into your RHS function and then iterating. But I’m not totally sure if i understand why that would work.
Thanks for the great code! very clean and fully featured

I've attached some code that I found that I used when we wrote the
paper. No guarantees that it'll work, though.

I fixed another issue in hedge's git tree, and
test_jit_discretization.py passes for me now.
