Error while 'using IncompressibleNavierStokes' about incompressiblenavierstokes.jl

Hi!
This package currently only works with Julia version 1.7 and above.
The (; a, b) = x syntax (short for a = x.a, b = x.b) was introduced in Julia version 1.7.
You may consider upgrading to the latest stable version of Julia, see https://julialang.org/downloads/.

Hi,
Thanks for the reply! I've upgraded Julia to 1.8.3 and I was able to overcome the above error. However, I have a new error when I execute the following command on my commandline (I am trying to run the example simulations),
julia-1.8.3 LidDrivenCavity2D.jl,
I get the following error:
Initial momentum residual = 0.05090339915871585 Iteration 1: momentum residual = 0.001034056530787347 Iteration 2: momentum residual = 0.0007818325375434987 Iteration 3: momentum residual = 0.000433200204905297 Iteration 4: momentum residual = 0.00023474593881534677 Iteration 5: momentum residual = 6.171949594050612e-5 Iteration 6: momentum residual = 7.567541449404942e-6 Iteration 7: momentum residual = 7.188702377374781e-9 Iteration 8: momentum residual = 1.0731243367881338e-14 ERROR: LoadError: UndefVarError: StateObserver not defined .

It seems that the function StateObserver is not being exported/loaded.
When manually loading the IncompressibleNavierStokes library (using IncompressibleNavierStokes) in the julia shell, I couldnt find the StateObserver variable/function.

Could you help me out with what is happening?

That function is not yet included in the latest release (v0.2), I can tag a release later so it becomes available.

In the meantime, you can try the example from the stable docs, see
https://agdestein.github.io/IncompressibleNavierStokes.jl/stable/generated/LidDrivenCavity2D/.
There it should be without the StateObserver interface. The script file is available here:
https://github.com/agdestein/IncompressibleNavierStokes.jl/blob/v0.2.0/examples/LidDrivenCavity2D.jl.

Hi,
Thanks for the information! I was able to get it working now.

Cheers!
