I tried the projection operation. However, it seems that the projection
gives the wrong solution. After projection, the bounding box is changed!
See logs below.
First, I patch the petsc4py by adding `DMProjectCoordinates`:
```
diff --git a/src/binding/petsc4py/src/PETSc/DM.pyx
b/src/binding/petsc4

Hi, I am using NASM as the outer solver for a nonlinear problem. For one of
the subdomains, I want to run the local solve with a different set of options
form the others. Is there any way to set options for each subdomain?

By default, they are stored as P2, not
