Is there any way to visualise the solution uh in this code

[https://gridap.github.io/Tutorials/dev/pages/t001\_poisson/](https://gridap.github.io/Tutorials/dev/pages/t001_poisson/)

other than writinfg it as vtk file.  
plot is not working.

There is [GitHub - gridap/GridapMakie.jl: Makie plotting recipes for Gridap](https://github.com/gridap/GridapMakie.jl) , and the readme actually contains a [section on 3D plots](https://github.com/gridap/GridapMakie.jl#3d-plots) which has the model from the Poisson equation tutorial you linked as an example.

So assuming you have run the tutorial as is, with the triangulation saved in `Ω` and the solution saved in `uh`, then running

```julia
using Gridap, GridapMakie, GLMakie
using FileIO

fig, ax, plt = plot(Ω, uh, shading=true)
Colorbar(fig[1,2], plt)
save("gridap_tutorial1_poisson_equation.png", fig)

```

gives

(I have rotated the plot a bit so it has more or less the same orientation as the one created from the `vtk` file in the tutorial.)
