Bernd,
Thank you. I submitted the merge request now.
Best regards,
Dmitry

Hi Dmitry,
strange, I didn't get notified about your access request. Anyway, I
set your personal project count to 10 so that you can fork.
Concerning the finger length, I'll believe anything as I'm not an
expert. Maybe someone else can jump in?
Kind regards
Bernd

Bernd,
it would be nice if you could share with us what you had to change to
make things work with Float128. Ideally, you would fork the
corresponding repository and create one or several merge requests
like described here:
I was about to make the merge request, but apparenly I can not fork
the dumux repo until I am given some privileges in the project. I
pushed the "request access" button and will see how it goes.
With "seems to work", do you mean that the irregularities vanish?
No, I just meant that the code compiles and runs. I am yet to see
whether I am able to set the residual criterion that makes the
irregularities sufficiently small for the time of simulation, and, at
the same time, allows the method to converge at all. That turned out
to be impossible with regular 64-bit floats. I will continue attempts.
If you want to quantify the influence of physical parameters on the
fingers, you have to apply measures that don't depend on the
numerical setting like grid size or solver thresholds. Which is
probably something like onset time, finger length and things like
that, but I'm certainly no expert here.
Oh, finger length certainly depends on grid size in my simulations.
With the grids I was able to try, anyway. The finer the grid, the
thinner and faster are the fingers. Maybe I have not yet reached the
grid resolution at which it is no longer the case. In fact, finger
length seems to be depending on everything (except maybe the time
step, though I am not 100% sure).
Best regards,
Dmitry
