does not have an associated "Action" error

Dear MOOSE users,

I have already had an input file to model oxidation which incorporates AC+CH+Tensor Mech.
Now, I want to modify it to have a bi-crystal model. To add the the Grain Growth equation only on my metal phase (grains)
I tried to add "ACGrGrPoly" and "ACInterface" kernels only to my metal phase (grains) eta_Fe and eta_Fe2. However, when I run the input I receive an error message of "section 'ACBulk00' does not have an associated "Action".

Can anybody help on this one?

I have attached the input file.

Hello

From your input file it looks like the kernel blocks you added (ACGrGrPoly ACinterface) are after the [] closing the Kernels. So MOOSE is searching for an action, rather than a kernel. They need to be moved up inside the
[Kernels]
...
[]
structure.

Best,
Guillaume

Oh, Thanks for catching that Guillaume!
