Hi all,
since recently, I'm doing time-dependent computations where
Navier--Stokes, the heat equation, and Maxwell's equations are
coupled such that the solution is composed of (u, p, theta, E, B), all
of which are living on the same mesh. When storing the files, I use a
separate file for each quantity and I eventually get a directory full of
velocity*.vtu
pressure*.vtu
temperature*.vtu
magnetic*.vtu
electric*.vtu
The total amount of data is easily in the range of several GB.
This becomes a bottle neck for storage and post-processing, so I was
thinking about ways to reduce this.
Try running your code in parallel, and see how many files you get then.
Assuming you are mainly interested in visualisation, XDMF files can
reduce the output volume considerably (and work with Paraview).
At the moment, you probably can't combine all fields into one file, but
you can do almost everything else you want.
To remove the automatic mesh saving, there is a parameter of XDMFFile -
"rewrite_function_mesh" which you can set to False.
