We've managed to solve an advection-diffusion problem
$$0 = \Delta \phi - \mathrm{Pe} (u \cdot \nabla \phi) $$
in cylindrical coordinates with $U$ coming from Stokes flow around a sphere using `…

In the hyperelasticity demo, there are terms that have been commented out:

I noticed that the hyperelasticity demo saves the Cauchy stress tensor to XDMF as a continuous function while it should in fact be a [tensor-valued] DG0 function. I tried to achieve that by saving to …

The `ElasticitySolver` implemented for linear elasticity does not converge for the linear solve in hyper-elastic problems (e.g., Saint Venant-Kirchhoff or Neo-hookean, the latter is the dev Gridap tut…

Thanks for making this awesome looking library. It looks amazing.
To try out `Ferrite.jl` I started with the `hyperelasticiy.jl` demo. I think it works fine, and if I add:
```julia
import Ferri…

After a conversation with my Prof. I noticed that we advertise a model that is not polyconvex as far as I understand.
$$
\Psi(\mathbf{C}) = \frac{\mu}{2} (I_1 - 3) - \mu \ln(J) + \frac{\lambda}{2}…

In the following scenario, we have a left muscle that is activated and contracts. This should result in the tendon moving to the left and that the right muscle (a passive muscle) elongating. The trans…
