Hey, I need to delete the face elements of the mesh shown. How can I achieve this?

I have a very complex meshing. For the face elements and the remaining elements, different material models have to be defined.  I have obtained the face elements using the 'find face'.  But how can I remove these elements from the parent mesh?

The green mesh is the parent mesh. And red elements are the face elements of the green mesh. How can I remove these face elements from the green mesh?

 

Thanks for the support.
