Use the Ribs panel to create and modify simple ribs between two surfaces.

Geometry definition is normally created in CAD systems and imported into the Engineering Solutions database. CAE modeling is done using the geometry available
in Engineering Solutions. From the CAE analysis results or from optimization
of the structures sometimes it is necessary to add stiffening ribs to the geometry.
It is not convenient to use the CAD system to add ribs and modify the dimensions or
its locations. Using this panel you can create and modify simple ribs between two
surfaces, but not more than two surfaces. Rib locations and thickness can also be
modified using the Dimensioning panel, with some limitations. Complicated ribs still
need to be created in the CAD system and re imported to Engineering Solutions. Figure 1. Triangular Rib Terminology Figure 2. Quadrilateral Rib Terminology
Define the location
and orientation of the rib. This plane is used as reference
geometry, with respect to which sides of the rib are
constructed. For example, when draft angle is zero, the two side
surfaces of the rib are parallel to this plane.
Select a rib
profile plane using the plane selector (x,y,z planes, vector
or a base node).
plane position
Select the rib
position from the profile plane (centered, on right or on
left).
rib start node
Select a rib start
node on a surface where the rib will start. You can modify this
during the preview. This will give the height of the
rib.
rib end node
Select a rib end node
on a surface where the rib will end. You can modify this during
the preview. This will give the length of the triangular rib or
the height at the other end of the quadrilateral rib.
height and
length
Specify the height and
length of the triangular rib.
height 1 and height
2
Specify height 1 and
height 2 of the quadrilateral rib. Provides heights at both ends
for the quadrilateral rib.
width
Specify the width of
the rib.
draft angle
Specify an angle used
for the side face inclination.
