Hi Daniel,
Thank you very much for your prompt reply.
I'm manually trying to implement the bound-checking feature immediately
following a sweep, as you've suggested. As an initial step towards this, I need
to manually compute my own residual and compare to that computed via '.sweep'
in FiPy.
Hi Ian,
Sorry, there isn't any way to do this as an implicit command in FiPy,
whether as a simple reset during sweeping or as a fully implicit
constraint in the equations. Of course, you can always try these
techniques explicitly in the Python code or in the design of the
equations. I agree that I
Hi All,
I would like to prevent the CellVariables I am solving for from ever reaching
physically-meaningless and incorrect values, such as concentrations becoming
negative. Is there a way to do this?
The most natural place I could think of it being is an argument in
CellVariable declaration,
Hi Nils,
Could you possible post your code so I can play around with it? I
can't think offhand what could be the issue or exactly what the error
is that you're calculating, it seems like the normalized residual or
something. This is a linear equation so I'm not entirely sure why the
non-linear res
Thank you -- since my problem solves for a stream function, this was a very
helpful tip, and has made my solutions appear much better.
