In the context of solving the Poisson equation one needs to identify the null frequency as a particular case. For now the user has to assume the null frequency is on the first position of the fourier …

Hi!
In task 7 we are required to implement rotation averaging for the faces using the absolute rotations, then perform stitching by solving the poisson equation. If I'm not mistaken, we don't take …

Working with @elise-palethorpe we see that the preconditioned conjugate gradient solver is much slower than expected. See #2654
In particular, benchmarks on solving the Poisson equation on a doubly…

In Gridap 0.18, Tutorial 17 (transient equations) is broken in multiple ways:
Most importantly,
```julia
u₀ = interpolate_everywhere(0.0,U(0.0))
t₀ = 0.0
T = 10.0
uₕₜ = solve(ode_solver,op,u₀,…

Hi
I've been working with your open-access code repository and have found the provided tutorials and documentation very helpful for installing and running simple simulations.
I am currently explorin…
