C3D4

Linear Tetrahedral

• Number of Nodes: 4

• Number of DoFs: 3 (All Translation)

• DoF Label: U1, U2, U3

• Supports Body Force

• Integration Scheme: Single Point At Centre

• Constant Consistent Mass Matrix With Same Order Integration

Syntax

element C3D4 (1) (2...5) (6) [7]
# (1) int, unique element tag
# (2...5) int, four corner nodes with conventional order
# (6) int, material tag
# [7] bool string, nonlinear geometry switch, default: false

Remarks

1. The nonlinearity is implemented by using total Lagrangian (TL) formulation, turn on the switch to use it.
