Geometric Properties ElementPBEAM9 lets you specify the geometric properties for an associated beam element of an arbitrary cross-section using
a polynomial expression
This manual provides a detailed list and usage information regarding command statements, model statements, functions and
the Subroutine Interface available in MotionSolve.
This type of property card is used to specify the geometric properties
of the BEAM element. Each beam property element must
have a unique identification number.
This property card defines the geometrical properties of the beam.
The material properties of the beam are defined by the material
specified by mid.
graph is a post processing flag that determines how this element will
be represented in the animation H3D file.
graph = "0" implies that
this element will not be represented in the H3D
graph = "1" implies that
this element will be represented as a line drawn between
the two connecting nodes.
Figure 1. The representation of a beam with graph = 1.
Note: When using
graph="0" or
graph="1", you will
not be able to visualize the stress, strain or displacement
contours. To do this, use
graph="2" or
graph="3".
graph = "2" implies that
the beam will be represented by 3D solid elements. This
mode is useful when trying to visualize the stress/strain
and displacement contours.
Figure 2. The representation of a beam with graph = 2. The beam is
represented by 3D elements
graph = "3" implies that
the beam is represented both as 3D solid elements as well
as a line connecting the two nodes of the beam. This is
useful when you need to visualize both the center line and
the 3D representation of the beam.
Figure 3. The representation of a beam with graph = 3. The 3d
elements in the middle of the beam are turned off to show
the center line of the beam
When representing the beam as a solid, the
arguments ngx, ngy and
ngz determine the number of elements that are
used to represent the beam in the animation H3D.
Figure 4. Effect of ngx, ngy and ngz on the 3D representation
of a simple beam
ngx = ngy = ngz = 1
Figure 5.
ngx = ngy = ngz = 2
Figure 6.
ngx = ngy = ngz = 3
While increasing the ngx, ngy and ngz
results in a better representation of the beam, it also increases
the post-processing time taken by MotionSolve to write out the H3D. In
addition, large values of ngx,
ngy or ngz will
increase the file size of the H3D considerably. Consider using
the minimum values of these attributes that satisfy your
visualization needs.
