Card 4a - Single Node

This optional card defines a node as a point in space by its coordinates.

Parameters: N, X1, X2, X3

N

N parameter is the node number between 1⩽N⩽999999.

Note:
Node number duplication is not permitted. and node dimensions should not exceed 0.5E6.

X1, X2, X3

X1, X2, X3 parameters are:
  • (X, Y, Z) coordinates of the node in the Cartesian (local or global) coordinate system.
  • (R, ϕ, z) coordinates of the node in the local cylindrical coordinate system defined by Card 4c.
  • (R, θ, ϕ) coordinates of the node in the local spherical coordinate system, which is defined by Card 4c. θ is the angle in degrees the radius vector makes with the local Z axis, ϕ is the angle in degrees the projection of the radius vector on the local XY plane makes with the local X axis (CCW is positive).
