commit fb3a2e86e4b3d663fc1a25aaf52784a45d6dd209
Author: Matthias Bussonnier
AuthorDate: Wed Dec 13 16:26:43 2023 +0100
Typo and UTF-8
It look like there is a typo in the conditional include, I guessing you
want to include only if not defined, but there is not the same number of
underscore in define.
Also one of the files are in ISO-8859 (latin1) I guess, which make clang
show warnings for `é` and a few other character, do not change content
but change to utf8, it seems to fix the warning. This has the side
effect of making the diff show the correct characters instead of
mojibake.

Explicitly opt-out of clang, got gcc specific instructions.
Clangs sometime pretends to be GCC or to support GNU C extensions but
does not. Thus skip GCC code when we are clang.

Re: [Getfem-commits] (no subject)
Dear Kostas, Indeed, it would be better to have a convergence threshold on a relative residual, so your suggestion to scale the convergence threshold with gmm::mat_maxnorm(G) is a very good idea. There is a sharper convergence threshold for the Newton algorithm in invert_nonlin() in order to have a sufficient accuracy to ensure a consistent result of point_in_convex(*pgt, x, res, IN_EPS). With a scaled convergence threshold, this ratio can probably be reduced, but a certain safety factor has to be kept, in my opinion. Best regards, Yves Le 06/04/2022 à 15:20, Konstantinos Poulios a écrit : Dear Yves, Thanks for the feedback. Still the check if the point lies in the convex is combined with a convergence check in the returned value. And this convergence check is less strict than the convergence result returned in the "converged" flag. So we have two different convergence criteria which is a bit confusing. Anyway, at some point, you had reduced the convergence threshold from IN_EPS to IN_EPS/1000 and then you increased it to the current value of IN_EPS/100. Do you remember the motivation for reducing the threshold? The problem is that the current threshold value works well for elements that are 1x1x1 or smaller and they are placed relatively close to the origin of the coordinates. If one needs to work with large elements e.g. 100x100x100, or small elements 1x1x1, which are far away from the origin, let's say at a distance of 1000 from (0,0,0), then the requested precision can never be achieved because of floating point arithmetics. Ideally, the geometric inversion should be done with the real element moved to the origin and normalized, but this would require quite some changes in this function. Another quick fix would be to multiply the convergence threshold with gmm::mat_maxnorm(G). I will think a bit about it.

Concerning the returned value and the convergence flag it has a different meaning : the inversion is sometimes used for extrapolation outside the element.

Dear Yves,
Thanks for the feedback. Still the check if the point lies in the convex is
combined with a convergence check in the returned value. And this
convergence check is less strict than the convergence result returned in
the "converged" flag. So we have two different convergence criteria which
is a bit confusing.
Anyway, at some point, you had reduced the convergence threshold from
IN_EPS to IN_EPS/1000 and then you increased it to the current value of
IN_EPS/100. Do you remember the motivation for reducing the threshold? The
problem is that the current threshold value works well for elements that
are 1x1x1 or smaller and they are placed relatively close to the origin of
the coordinates. If one needs to work with large elements e.g. 100x100x100,
or small elements 1x1x1, which are far away from the origin, let's say at a
distance of 1000 from (0,0,0), then the requested precision can never be
achieved because of floating point arithmetics. Ideally, the geometric
inversion should be done with the real element moved to the origin and
normalized, but this would require quite some changes in this function.
Another quick fix would be to multiply the convergence threshold with
gmm::mat_maxnorm(G). I will think a bit about it.

Re: [Getfem-commits] (no subject)
Dear Kostas,
You are right of course. This change has been done after experiencing
some difficulties of convergence for the pyramid element. I think the
test (factor < 1.0-IN-EPS) does not change a lot of things but may be it
is slightly more robust in some situations, but the change "factor *=
2.0" in "factor = 2.0" is simply a nonsense.
Concerning the returned value and the convergence flag it has a
different meaning : the inversion is sometimes used for extrapolation
outside the element. The returned value indicates only if the point is
inside the element (with possibly a successful convergence) and the flag
returns whether or not the convergence was successful.
This portion of code can probably be improved, yes !
Best regards,
Yves

Dear Yves,
Another thing that seems illogical to me is that
geotrans_inv_convex::invert() returns convergence information, both as
a return value and through a boolean argument "converged", with two
possibly different values. Shouldn't we simplify this?
The reason that I am looking into this is because I am experiencing
some geometric inversion failures which are due to too strict checks
with IN_EPS/100. But I don't want to just change the threshold value,
I would like to improve the robustness of this quite central function
in general.
