[petsc-users] DMPLEX project function error

[Ellen M. Price]

I was working with a DMPLEX and FEM, following SNES example 12. I get
the following error when I call DMProjectFunction, but I don't know what
it means. Can anyone explain where I might have gone wrong, or at least
what this error is telling me? I think the point closure size is
correct, since my mesh is 3d simplex, but what is the dual space
dimension, and where might I have set it incorrectly?

(I know this is an optimized PETSc build, but I get the same error from
my debug build, it's just much slower.)
