Dear all,

Do you know if it exists an equivalent of the finite element “P0edge” in 3D (on tetrahedra), that is to say a piecewise P0 discontinuous finite element contained on each face of the mesh ?

Thank you in advance,

Best regards,

Loïc,

The equivalent are : P0face3d and P0facedc3d

Are there any higher-order finite elements (eg. P1face3d, P2face3d ) like P0face3d and P0facedc3d in 3D?
