[petsc-users] How to use AD for unstructured grid

[behzad baghapour]

Dear developers,

I need to evaluate Jacobian matrix using an AD tool. I read from the Petsc
manual that it can only work with structured grid via DMMG interface. Is
there a possible way to use it for unstructured grid and set it for KSP
structure?

Thanks,
BehZad
