Overview
New functionality and updates
• Preprocessing
• Meshing
• Solver support
• Postprocessing
• Performance

Preprocessing
Draw/Erase Toolbar
• New toolbar for draw/erase
• Fast access to mesh and geometry on/off
• Choose entities to draw or erase
• Toggle back and forth
• Choose by element, property, material
• Grow/shrink selection
• Mesh only, geometry only, or linked
• Create Femap group from draw/erase data
• Load Femap group into draw/erase data

Preprocessing
New View Rotation Options
• Default option still “Rotate about View Center”
• Similar to v11.2.x – first two items toggle between view center
and rotation center
• New option – choose between rotating about the “view axes”
(screen) or the “model axes” (global csys)
• New option – “Rotate about Coordinate System” – simply pick
a Femap csys
• “Rotate around vector” same as v11.2.x “rotate around
rotation axis”
Femap v11.2.x

Preprocessing
Rotate Around Cursor
• Accessed via File / Preferences / User
Interface OR add a toolbar icon
• Model rotates about the closest entity on
screen
• Model never swings out of view!
Pick Here

Preprocessing
Zoom Around Cursor
Accessed via File / Preferences / User Interface OR add a toolbar icon
Zoom Here

Preprocessing
Roll Through Mode
• Roll-Thru: move “inside” the model
With Roll-Thru off (and in all previous versions of
Femap) you cannot move through your model, you
just zoom closer and closer
• Roll-Thru moves the viewer’s eye to a certain
depth in the screen direction, everything behind
that is clipped
• Zoom in enough and you’re
inside, and can turn around
and see what was behind you

Preprocessing
Touch Gestures
Graphics Window Gesture Action
One finger drag Dynamic model rotate
Two finger drag Dynamic model pan
Two finger pinch Zoom out
Two finger spread Zoom in
Move one finger around another Rotate around screen z-axis
Touch gestures are available in Graphics and Messages Windows, Entity Editor, Meshing and
Postprocessing Toolboxes, Data Table, Connection Editor, Model Info Tree and Status Bar

Preprocessing
Connection Manager
• New connection editor
• Easier management and access to connections
• Direct editing
• Sorting
• Filters

Preprocessing
Streamlined Element Face Picking
• Face picking automatically loads currently displayed
elements as possible entities to pick from
• Adjacent faces is now the default
• With front picking turned on, only front faces can be
selected, so any face based selection can be made
with a single double-click

Preprocessing
• Combined with the Draw/Erase toolbar, connection
setup for mesh only parts is much easier and faster
• Workflow:
• With the front picking option turned on
• Choose draw on the Draw/Erase toolbar, and
select the Element option, then pick one element
on each leg
• In the selection box, choose Add All Connected
Elements
• Click OK

Preprocessing
• Workflow (continued)
• Go to Connect / Connection Region, choose elements,
select the Add Multiple button
• The visible elements are already loaded, pick one on the
end and click OK
• All the connected faces are picked automatically, repeat
each time for the ends
• In just a couple of clicks, six connection regions are
created

Preprocessing
Workflow (continued)
• While still in the Connect / Connection Region command,
you can use the Draw/Erase toolbar to swap the drawn
entities to pick the other side of the connection

Preprocessing
Beam Modeling Enhancements

Preprocessing
Pick Visible
New method for front picking
• Turn on/off in File / Preferences / Graphics
• Much faster than database access
• Uses OpenGL (basic and performance)
to keep track of which ID is front
• If an entity is not represented by a pixel,
it will not be picked, i.e. blocked by
something else, or so small it did not
make a single pixel
• Works in single pick, box, circle,
polygon, etc.

Align… menu. Similar to Between Coordinate Systems method, with
specified plane defining X and Y axes, plane normal defining Z axis.
• Loads
• Added ability to modify the color, modify the layer, scale the values,
change the function ID, or delete loads of specified type(s) in the active
Load Set, All Load Sets, or any number of selected Load Sets.
• Updated Modify, Update Other, Load Phase and Delete, Model, Load -
Body commands to allow selection of any number of Load Sets.
• Constraints
• Added ability to modify the color, modify the layer, or delete constraints of
specified type(s) in the active Constraint Set, all Constraint Sets, or any
number of selected Constraint Sets.

Meshing
Quad Meshing Improvements
• Max Quads
• Goal: all quad mesh through triangle removal
• Will allow triangles when required
• With an odd number of edges there will always be one triangle
• Example: default mesh contains 39 triangles – with Max Quads it’s just 1
Default mesh Max Quads mesh

Meshing
• Max Quads
• Mesh size changed by 1 – all triangles removed!

Meshing
Max Quads combined with Quad Layers provides maximum mesh
customization and flexibility

Example:
• From an existing Nastran input file imported into Femap, mesh refinement is
required in the two areas indicated

Meshing
Example (continued)
• At the T junction use Split Edges option
• Choose Edges
• Grow
• Done

Meshing
Example (continued)
• At the hole, refine using Split Edges twice

Meshing
Example (continued)

Meshing
Multiple Element Splitting
• Multiple elements (nodes) can be
selected for splitting in a single
command
• More efficient mesh refinement
process

Meshing

property titles

Solver Support
ANSYS & Abaqus CBUSH/PBUSH Input
• General Issue: ANSYS and Abaqus do not have an element which exactly
matches the (CBUSH/PBUSH in Nastran) Spring/Damper element in Femap
• Additional Requirement: Spring/Damper elements must behave like
CBUSH/PBUSH when solved with ANSYS or Abaqus, otherwise different
results are calculated
• Possible Solution: Simply include stiffness and damping of Spring/Damper
elements when creating input files for ANSYS or Abaqus
• Our Solution: Spring/Damper elements are written as MATRIX27 elements
for ANSYS; written as *MATRIX INPUT for Abaqus; with matrix values
(stiffness and/or damping) calculated using the same approach as
CBUSH/PBUSH
• Limitation: nonlinearity and frequency dependency are ignored, as the matrix
entries are calculated only once

CBUSH Translation Notes
• For ANSYS:
 PBUSH to MATRIX27. K and B to two elements, one for K, another for B.
 SPRING/DAMPER to COMBI14.
 “To Ground”: creating a dummy node and apply “D,dummyNode,ALL,ALL”.
• For Abaqus:
 PBUSH to *MATRIX INPUT,… *MATRIX ASSEMBLE. K and B, two matrices.
 Spring (K input) to SPRING2/A, Damper (B input) to DASHPOT2/A.
 PBUSH to Ground, only top-left quarter (11) sub-matrix is written.
 SPRING to Ground (K input) to SPRING1.
 Damper to Ground (B input) to DASHPOT1.
 *MATRIX INPUT,… *MATRIX ASSEMBLE not applicable to analysis other than statics/mode, for other analysis,
CBUSH is not translated and warning is issued.

Solver Support
MATRIX27 input from Femap
Because PBUSH is translated to MATRIX27 of ANSYS and MATRIX27 is
12x12, A 12x12 matrix (K,B,M) is added to Femap to handle its input from

Nonzero constraints in ANSYS
• Nonzero constraints were added in Femap 11.3
• Nonzero constraints are easily added to ANSYS as follows
• D,nodeID,dofID,value
• “D,nodeID,dofID,value” are read into Femap 11.3 and stored as a constraint with
nonzero value

Postprocessing
Arrow Plots
Contour Vector plots have been completely overhauled for v11.3 and have
been renamed Contour Arrows

Postprocessing
Contour Arrow Plots
Automatic vector selection: the user specifies a single contour vector and
Femap automatically selects appropriate output vectors to display as well as
the correct orientation for relevant elements
Individual output vector selection is still available for advanced users
