I am struggling to get the nonlinear solver to work.

I am probably misconfiguring jacobian and residual matrices - maybe
not properly setting boundary conditions, not sure. My testcase is a
simple linear elasticity equation, which worked previously in the
linear approach.

Can someone perhaps point out the "simplest example" of the
Any piece of code would really help.

I went through the examples and the mailing list, without success.

Thanks in advance,
