Element Types available in Gmsh

[dimtsap]

I am posting here the manual of elements available in the GMsh preprocessor/mesh generator that could be added in the MSolve. http://www.manpagez.com/info/gmsh/gmsh-2.2.6/gmsh_63.php Till now we have Quad4,Tri3, Tri6 implementations of @SerafeimBakalakos and Hexa8.

Also note that many element types that can now be easily incorporated into MSolve due to the continuum element/ interpolation/ integration separation can be found in https://www.colorado.edu/engineering/CAS/courses.d/AFEM.d/AFEM.projects.d/AFEM.projects.2006.d/AFEM.pr.06.CMM.d/CarlMullerMeadows.report.pdf

Εξαιρετικά χρήσιμο το Calculix και για το developement και για validation! Ευχαριστούμε πολύ Δημήτρη.

We also have Quad8 and Quad9 elements. All 2D elements have been tested against Abaqus or other sources, with the exception of Quad9 which is not supported by Abaqus.

All 3D finite elements of Gmsh are now also implemented. Specifically:

• [x] Tet4 - Linear tetrahedron with 4 nodes.
• [x] Tet10 - Quadratic tetrahedron with 10 nodes.
• [x] Hexa8 - Linear hexahedron with 8 nodes.
• [x] Hexa20 - Quadratic serendipity hexahedron with 20 nodes.
• [x] Hexa27 - Quadratic hexahedron with 27 nodes.
• [x] Wedge6 - Linear prism with 6 nodes.
• [x] Wedge15 - Quadratic serendipity prism with 15 nodes.
• [x] Wedge18 - Quadratic prism with 18 nodes.
• [x] Pyra5 - Linear pentahedron with 5 nodes.
• [x] Pyra13 - Quadratic serendipity pentahedron with 13 nodes.
• [x] Pyra14 - Quadratic pentahedron with 14 nodes.

Apart from Pyra14 all the above elements have been tested for shape functions and cross-ckecked their derivatives. Abaqus supports only Tet4, Tet10, Hexa8, Hexa20, Wedge6, Wedge15, so their stiffness and mass matrices wil be checked next.
