Elmer Discussion Forum

I am looking to determine the mesh element type (hexahedral? tetrahedral?linear brick?) used in the wire geometry associated with tutorial 7 in the Elmer GUI Tutorials.

Thank you for any information you can provide.

Hex, 808 code in Elmer.

wire,grd defines a 2D quad mesh that is rotated 360 degrees into a solid mesh. Although most of the elements come out 808 Hex, the ones on the axis come out 404 solid triangle elements.

Hi

The general logic of the code is actually 100*NumberOfCorners+NumberOfNodes. So 404 is actually quadrilateral linear element, 408 is quadratic etc. Unfortunately quads and tets have both 4 corners, so tets got the family 5, which pushed pyramids to family 7. Prisms are 6 as they should.

Thank you. The naming convention for the different element types? 404 - quadratic, 808 - hex, etc. Is this information provided in the Elmer documentation? If so, which manual would it be?
