Represents 3D linear pyramid element for transient incompressible flow analysis using SUPG/PSPG stabilization with equal order approximation of velocity and pressure fields. Each node has 3 degrees of freedoms (two components of velocity and pressure). The element features are summarized in Table 64.
Keyword  TET1SUPG 
Description  linear equal order approximation axisymmetric element 
Specific parameters  [vof #(rn)][pvof #(rn)] 
Unknowns  Three velocity components (V_u, V_v, and V_w) and pressure (P_f) are required in each node. 
Approximation  Linear approximation of velocity and pressure fields. 
Integration  exact 
Loads  Constant boundary tractions are supported. Body loads representing the selfweight load are supported. 
Multifluid analysis  The element has support for solving problems with two immiscible fluids in a fixed spatial domain. In the present implementation, a LevelSet tracking algorithm is used to track the position of interface. The material model should be of type Keyword: twofluidmat, that supports modelling of two immiscible fluids.
