Element Types

2D Pore Pressure Element

FP2D2

2-node linear

Active Degrees of Freedom

8

Additional Solution Variables

None.

3D Pore Pressure Element

FP3D2

2-node linear

Active Degrees of Freedom

8

Additional Solution Variables

None.

Nodal Coordinates Required

Element Property Definition

The fluid pipe elements FP2D2 and FP3D2 are defined by two nodes, which cannot be coincident (a zero-length pipe is not allowed).

You must associate a fluid pipe section with a set of fluid pipe elements.

Element-Based Loading

Distributed Loads

Distributed loads are specified as described in Distributed Loads.

*dload
  1. Load ID (*DLOAD): GRAV
  2. LT−2

  3. Gravity loading in specified direction (magnitude is input as acceleration).

Element Output

FPDPRESS

Pressure drop across the element.

FPMFL

Mass flow rate through the element.

FPFLVEL

Velocity of the fluid flowing through the element.
