Y Direction for Beams
You specify the
orientation of the XY plane of a beam by defining its Y direction with respect to the WCS on the
Beam Definition dialog box. The X axis is along the length of the beam. For the Y direction, you can enter vector coordinates, or select a geometric entity to specify a direction.
Creo Simulate then defines the Z axis of the beam action coordinate system as perpendicular to the XY plane. The Y and Z axes you define in this way orient the
BACS.
You can define the Y direction of a beam by selecting any of the following options:
• Y-Direction defined by Point—Define the beam's XY plane by the X axis of the beam and its Y vector, which extends from the start point of the beam to the selected datum point or vertex.
• Y-Direction defined by Edge—In FEM mode only, define the beam's XY plane with the beam's X vector and the projection from the start point of the beam toward the selected edge.
• Y-Direction defined by Curve—In FEM mode only, define the beam's XY plane with the beam's X vector and the projection from the start point of the beam to the selected datum curve.
• Y-Direction defined by Axis—Define the beam's XY plane with the beam's X vector and a parallel vector to the selected axis, passing through the beam's start point.
• Y-Direction defined by Surface—In FEM mode only, define the beam's XY plane with the beam X vector and the projection of the start point of the beam to the selected surface.
• Y-Direction defined by Vector in WCS—Define the beam's Y direction by entering the X, Y, and Z components of a vector. The default is 0, 1, 0, which specifies a Y direction parallel to the positive Y axis of the WCS.
