Is automatic remeshing for higher order 3D elements possible?

Is automatic remeshing for higher order 3D elements possible?

(OP)
Hi, all. I'm attempting to model growth of solid A embedded in solid B in APDL. Volume A grows (through a simulated thermal expansion) while volume B is compressed due to adjacent growth of A. Elements are higher order tetrahedrals due to irregular curved geometry. Deformations of the 3D elements in both components are large. Due to said large deformations, I need to introduce some form of remeshing into the solution phase.

Is it at all possible to have mesh nonlinear adaptivity (NLADAPT) for 3D higher order elements? I've only come across lower order SOLID285 for now.

In the event that mesh nonlinear adaptivity is in fact NOT available for higher order tet elements, would it be recommended to:
1) Use mesh nonlinear adaptivity with a finer mesh of 3D linear elements?
or
2) Define manual remeshing/rezoning for higher order 3D elements?

Many thanks!
