High order elements
Hi. I want to use high order elements so that i can represent boundaries (wall) with good accuracy. I have seen some mesh generators which represent the boundary with 27node hexahedral in order to describe the geometry with second order polynomial (3 nodes at each edge). Is there any way (64 or more nodes hex) for representation of more high order accuracy?

Is there any way (64 or more nodes hex) for representation of more high order accuracy?
There is an 8node hex Hermite element with 32 degreesoffreedom (scalar & 3 first derivatives at each node) which is a complete cubic.
