  • At the moment, for some BCs (especially in TopOpt), the petsc version converges but the jax_solve does not.
  • From our tests, we understood that this is due to the lack of a good preconditioner. PETSc solver has ilu as the preconditioner while the jax solver is using a simple jacobi

Can we implement an ILU preconditioner for jax solver ?
