I noticed this in the TAOALMM manual page.
It is also highly recommended that the subsolver chosen by the user utilize a
trust-region
strategy for globalization (default: TAOBQNKTR) especially if the outer problem
features bound constraints.
I am far from an expert on these topics.

I am still working to understand. I have a PETSc branch
barry/2022-11-11/fixes-for-tao/release where I have made a few fix/improvements
to help me run and debug with your code.
I made a tiny change to your code, passing Hessian twice, and ran with
./test_tao_neohooke
That makes sense. Thanks for the quick reply!

Under what conditions can I use LSC preconditioning for field split
problems with Schur? Let's imagine that all I've done is called
SNESetJacobian with global A and P and provided the index sets for 0 and 1.
Based off of the documentation on the man page
Hi guys,
anyone with any suggestion to make this thing work? 梁
