Initial Conditions PropertyManager

The Initial Conditions PropertyManager applies initial displacements, velocities or accelerations for modal time history and nonlinear dynamic studies to entities at time 0.

To display this PropertyManager:

Create a Linear Dynamic time history or Nonlinear Dynamic study. Right-click External Loads and click Initial Conditions.

Type

Sets the type and location of the initial condition.

  Displacement  
  Velocity  
  Acceleration  
Components, Bodies, Faces for Initial Condition Select bodies or components to apply initial conditions. For shell and sheet metal bodies, you can also select faces.
Beams Available for studies with beams only. Select the beams to apply initial conditions.
Joints Available for studies with beams only. Select the beam joints to apply initial conditions.
Face, Edge, Plane, Axis for Direction Select an entity to define direction.

Displacement, Velocity, or Acceleration

Sets the units and values of the initial condition components.

Units Sets the units.
    If you select a planar face or a reference plane, you can specify initial conditions Along Plane Dir 1 ,Along Plane Dir 2 PM_along_plane_dir2.gif, or Normal to Plane .
    If you select a cylindrical face or a reference axis, you can specify initial conditions in the Radial, , Circumferential , or Axial directions.
    If you select a straight edge, you can specify initial conditions along the edge alongedge.png.
The initial velocity is relative to velocity of Uniform Base Excitation, if you do not specify the initial velocity, the solver assumes that initial velocity of the entire structure is equal to the velocity of the Uniform Base Excitation at time = 0, the dynamic response is based on this initial condition.
