Hi all, I am working on system that requires me to start with a 4th order element since the mesh for the domain is prescribed from an external source. Now, since libMesh does not have 4th order lagrangian elements and since I'm lazy to learn a new package (and since I'm constrained in time), I decided to implement higher order lagrange elements (EDGE, QUAD, HEX only for now) till order 5. But on my first look to proceed with this idea, I noticed that there is an embedding matrix that is prescribed for every element. And I do not exactly understand the usage of this array in the bigger picture. If someone can help me understand what exactly it represents, it would be tremendously helpful for me in the implementation.
I might have posed a similar question couple of years ago in the context of higher order elements but when I'm done testing, I definitely can create a patch to add the functionality to the library, even though my focus is only for limited elements.
