Hello everyone,
I am using step-46 as starting point to implement a time dependent fsi
problem using block vectors and block matrices.
I successfully written the time iteration and changed everything to block
structures but I am struggling to find a method to impose the fluid
velocity equal to

Hello everyone,
I am trying to implement a continuous mechanics simulation and I am
encountering troubles trying to compute the divergence of the deformation
gradient inverse. I need it to assemble the variational form terms.
My code reads something like the following:
- take the gradient of the
(u)^T)] Finv*
Then I guess that using get_function_hessians() on *u* is what I need to
assemble correctly my weak form.
Thank you again!

Yes, thank you for the warning, that could be an issue indeed. In my case I
am using P2 elements, I'll check the best way to approach this, thank you!
