Improve pressure handling in incompressible Navier Stokes example

[termi-official]

Pressure handling does not work very consistently for now, because the current choice for the solver does not resolve the constant consistently.

We will work on this once SciML/OrdinaryDiffEq.jl#1570 is resolved

I thought #917 solved this, but seeing the following failure here? Is that related?

Technically yes, but the solution is not very clean yet.

Also, I cannot reproduce the error and master CI is also green. Will try to take a look next week, but I am really tight on time, so do not expect too much from my side on this.

Should we just disable this test then, and use this issue to track its solution?
Possibly also add a warning to the example?

It's a bit annoying with sporadic unrelated CI failures...

If we change something which triggers failure in the CI we should first investigate why the CI fails.

While I agree that sporadic CI failures are annoying, this issue is actually related to the linked example drove gmsh into a faulty state. See #799 (comment) .
