Detailed Description

Element traits for 6-node linear prism (Prism6)

Prism6 is a 3D prismatic element combining triangular and quadrilateral faces. Commonly used for:

  • Boundary layer meshes
  • Extruded 2D meshes
  • Regions with strong anisotropy

Geometry:

  • Reference prism: triangle base extruded along z-axis from -1 to +1
  • 6 nodes at the vertices (3 on bottom, 3 on top)
  • Parametric space volume = 1.0

Faces:

  • 2 triangular faces (top and bottom)
  • 3 quadrilateral faces (sides)

Member Function Documentation

◆ GetFaceType()

static constexpr ElemType DNDS::Geom::Elem::ElementTraits< Prism6 >::GetFaceType ( t_index  iFace)
inlinestaticconstexpr

Get the element type of a face.

Parameters
iFaceFace index (0-2 are quads, 3-4 are triangles)
Returns

Definition at line 160 of file Prism6.hpp.

Member Data Documentation

◆ dim

constexpr int DNDS::Geom::Elem::ElementTraits< Prism6 >::dim = 3
staticconstexpr

Definition at line 124 of file Prism6.hpp.

◆ elemType

constexpr ElemType DNDS::Geom::Elem::ElementTraits< Prism6 >::elemType = Prism6
staticconstexpr

Definition at line 123 of file Prism6.hpp.

◆ elevatedType

constexpr ElemType DNDS::Geom::Elem::ElementTraits< Prism6 >::elevatedType = Prism18
staticconstexpr

Element type after order elevation (O1 -> O2) Prism6 elevates to Prism18 (18-node quadratic prism)

Definition at line 189 of file Prism6.hpp.

◆ elevNodeSpanTypes

constexpr std::array<ElemType, 12> DNDS::Geom::Elem::ElementTraits< Prism6 >::elevNodeSpanTypes
staticconstexpr
Initial value:
= {
Line2, Line2, Line2,
Line2, Line2, Line2,
Line2, Line2, Line2,
Quad4, Quad4, Quad4}

Element type of each elevation span.

Definition at line 210 of file Prism6.hpp.

◆ elevSpans

constexpr std::array<tElevSpan, 12> DNDS::Geom::Elem::ElementTraits< Prism6 >::elevSpans
staticconstexpr
Initial value:
= {{
{0, 1}, {1, 2}, {2, 0},
{0, 3}, {1, 4}, {2, 5},
{3, 4}, {4, 5}, {5, 3},
{0, 1, 4, 3}, {1, 2, 5, 4}, {2, 0, 3, 5}}}

Elevation spans define new node connections.

Elevation creates 12 new nodes: Spans 0-2: bottom triangle edge midpoints Spans 3-5: vertical edge midpoints Spans 6-8: top triangle edge midpoints Spans 9-11: side face centers

Definition at line 203 of file Prism6.hpp.

{1, 2, 5, 4},
{2, 0, 3, 5},
{0, 2, 1},

Node indices for each face.

Face 0: nodes 0-1-4-3 (side, quadrilateral) Face 1: nodes 1-2-5-4 (side, quadrilateral) Face 2: nodes 2-0-3-5 (side, quadrilateral) Face 3: nodes 0-2-1 (bottom, triangle) Face 4: nodes 3-4-5 (top, triangle)
