starting solution vs restart
by Islam El Salawi
Hallo Andreas,
Once you said relating importing starting solutions to hedge:
"What you need to provide hedge is a set of nodal values at the
interpolation nodes it generates for you. If you can somehow interpolate
your existing solution to those nodes, you should be good to go. For
example, on a triangle, first order nodes will sit at the vertices, and
second-order nodes will sit at vertices and edge centers. If you can
make those locations for your grid coincide with data you already have,
you don't even need to interpolate."
Is this supposed to be done as well as when I interrupt a run or a run is
crashed
by any reason or is there any shorter and faster way ?
Regards,
Islam

Re: [Hedge] python c++ mismatch
by Islam El Salawi
Hi Andreas,
thanks for your response. I'd like to know, whether you are able to run the
square.py example. I'm just wondering, because you told me, maybe I am not
feeding hedge with the right date types. But I am not feeding anything, I
am just trying to run the square.py example and then this error comes up.
I took your advice and debugged the square script and all arguments of arg
were of type numpy array float 64, except the first two of them, which were
something like uniform element or something.
I even reinstalled hedge and took another version of boost, but it still
does't work out.
I'm stuck and I really need help to move on with my calculations. Thanks
regards,
Islam
PS: I think I might found a mistake in square.py. make_box returns 4
variables but there are only 3 given to accept the transferparameter in
line 45. When I remove one return value in make_box, it works and no error
message shows up.
