Hi all, I've imported a mesh from gmsh that contains a layer of *pyramids* for transitioning between hexes and tets using: *NekMesh JICF_NektP2_2comp.msh JICF_NektP2_2comp.xml* Output: *Multiple elements in composite detected; remapped:- Tag 1 => 11 (Tetrahedron), 10 (Pyramid), 1 (Hexahedron)* No problem on NekMesh level. Defining my expansion as: *<E COMPOSITE="C[1,10,11]" NUMMODES="3" FIELDS="u,v,w,p" TYPE="MODIFIED" />* when I run (Nektar++ v 4.4.1) using: *mpirun -npernode 28 -np 56 IncNavierStokesSolver -v JICF_NektP2_2comp_xml conditions_JICF_2D.xml* (using prepartitioned mesh). I get the following "note": *Collection Implemenation for Tetrahedron ( 3 3 3 ) for ngeoms = 24960Note: Implementation does not exist: Pyramid, BwdTrans, SumFac, ModalNote: Implementation does not exist: Pyramid, IProductWRTBase, SumFac, ModalNote: Implementation does not exist: Pyramid, IProductWRTDerivBase, SumFac, ModalNote: Implementation does not exist: Pyramid, PhysDeriv, SumFac, ModalNote: Implementation does not exist: Pyramid, BwdTrans, SumFac, ModalNote: Implementation does not exist: Pyramid, IProductWRTBase, SumFac, ModalNote: Implementation does not exist: Pyramid, IProductWRTDerivBase, SumFac, ModalNote: Implementation does not exist: Pyramid, PhysDeriv, SumFac, Modal* What does it mean? How can I fix it? Do Pyramids need to be treated in a somewhat different way? BR, Vishal --- *Vishal SAINI*
