Using second order elemets but error message also occured

[killuaLeo]

I used second order Hex element Using NEPER. However, when using FEPX to do simulation, the error message occurs that:
Error : > Mesh requires second-order elements.
Could anyone help me with this issue? Thanks!

@killuaLeo FEPX only uses 10-node (second-order) tetrahedral elements, per the documentation.

But when I tried to create tetrahedral mesh on NEPER, there is error information shown:

neper -M 200-ori.tess -elttype tet -dim 3 -order 2 -cl 0.03

This is a question for the Neper discussion forum, and I suggest including all commands (tessellation and meshing) to give the proper info.
