The coordinates of node points in the finite element mesh are stored in this block.

Syntax

BEGIN NODES [NUMBERED] [COMPONENTS = Ncomp (Ncomp <= 6)]
[Node Number] X-Coordinate Y-Coordinate [Z-Coordinate] [U, V, W, P, T, ε]
END

For example, the syntax for a three-dimensional flow geometry is:

BEGIN NODES NUMBERED
1 0.0 0.0 0.0
2 1.0 0.0 0.0
: : : :
END

 

Comments

Numbering of nodes is optional. HyperXtrude treats unnumbered nodes sequentially, storing them in the increasing order starting from 1. Numbered nodes need not be entered in any particular sequence.  HyperXtrude stores nodes in the proper locations in the coordinate array. The Z-coordinate is required only for three-dimensional geometries.  COMPONENTS are read only if they are available as initial guess. The definitions for these components are:

 U        X-Component of the velocity vector.

 V        Y-Component of the velocity vector.

 W        Z-Component of the velocity vector.

 P        Pressure.

 T        Temperature.

 e        Strain.

 

Components must be entered in the same sequence:

Ncomp = 6 for metal extrusion and polymer extrusion problems.

Ncomp = 4 for isothermal Newtonian fluid flow problems.

Ncomp = 5 for nonisothermal Newtonian fluid flow problems.
