The following article describes the use of the load.sin command. This command defines a sinusoidal load.

Syntax

load.sin(node,dof,alpha,omega,phi)

where

Parameter	description	type	default
node	The acting node	integer	-
dof	The acting dof	float	-
alpha	Width	float	-
omega	Frequency	float	-
phi	Angle	float	-

Examples

Create a sinusoidal load at node 1 dof x with magnitude f(t)=1.5sin(πt+π/2).

 node.sin(1, 2, 1.5, 3.14159, 0.5*3.14159)
