[petsc-users] Requesting help with SNES non-linear example

[Vaishak Prasad]

Dear All,
Greetings from India.

I am new to petsc4py. I was trying out the example on slides 18, and 19 at

https://urldefense.us/v3/__https://www.bu.edu/pasi/files/2011/01/Lisandro-Dalcin-petsc4py.pdf__;!!G_uCfscf7eWS!ehNmddsrNhTg2K1fvJVZhjNXm7zt2pz25zK1Th5iKAIPiWNt4cl3DL63Z2e4zzZ0-e1Ff4Xg7-UB4QGl2eBfEVBffcVp$ 

However, I get a zero vector for the solution `x`.

I am using petsc4py 3.21.3 on Linux.

Any help would be appreciated.

With regards
