Analysis Studies
Organize output sets into analysis studies
• Analysis study creation:
• Automatically during import or results attachment
• Manually from existing results
• Organize any number of output sets into an
analysis study
• Easy to find, delete, or operate on all output sets
from a single analysis run (for example, collect all
time steps from a transient analysis)
• Control whether studies will be automatically
created and how they are titled in File Preferences

• Similar to Load Case Combination
Data Surface – different factors can
be entered for each output set using
a spreadsheet-like form
• Result Data Creation options create new virtual output sets
• Create All Immediately: all data needed for combination / envelope sets are
created immediately and stored in the database (longer initial creation, faster
results display)
• As Needed / Temporary: all data needed for combination / envelope sets are
created on-the-fly (faster initial creation, potentially longer display time)

Freebody Section Cuts
Freebody Section Cut modes
Plane: Cutting plane is defined via base
point and normal vector. Path is defined as
the normal vector; cutting plane will always
be normal to the path
Plane / Vector: Similar to Plane, however an
additional vector is defined for the path. The
cutting plane will always remain co-planar to
the original plane and does not have to be
normal to the path
Vector: Cutting plane is normal to the
defined vector. Path is the defined vector;
cutting plane will always be normal to the
path
Curve: Cutting plane is normal to the
tangent vector at a point along the plane.
Cutting plane will always be normal to the
tangent vector

interactively within the available entities
• Section cut entities may be limited to a

distance from the base location of the
cutting plane
• The cutting plane can optionally be given a
thickness tolerance that will allow for
accurate selection of entities that are
slightly out-of-plane

Freebody – Other Enhancements
Freebody Contributions From – Nodal Summation contribution – Reverse Values
• The Nodal Summation freebody
contribution can now be reversed
• This is the value calculated by the
solver that is the summation of the
solver calculated contributions
(non-rigid elements, SPC, MPC,
and applied), not the summation
calculated by Femap
• Imbalances, such as glue and contact
forces, can be treated as a
contribution by reversing the sign

and enable “Relative to” option
• For nodal vectors, the position is
relative to the selected node
• For elemental vectors, the position
is relative to the centroid of the selected

Miscellaneous Enhancements
ANSYS
• Added support for reading and writing both linear and parabolic pyramid
elements
Linear & Nonlinear Results Recovered in Same Output Set
• Due to historic reservations of Output Vector IDs, there was simply no where to
put them
• Use MSC MARC reserved nonlinear data vectors to store nonlinear results
Connection Regions
• Improved performance of expanding connection regions in certain cases. For
example, model with 692 regions and 400,000+ solid elements previously took
~9 minutes to write a Nastran file, now takes ~4 seconds (135 X performance
increase)

Groups
• Added Group | Operations | Generate Model Data Value command to
automatically create groups of elements with the same or similar values (i.e.,
same Young’s Modulus or same planar thickness, within given range)
Spaceball or any 3-D Mouse
• Updated Femap code to respond to driver changes which caused problems,
some of which caused Femap to become unresponsive. In short, the drivers
now send significantly more move messages, at very short intervals that could
cause problems (fixed for 11.1.1 or 11.1.2)
• December 2014 – During Femap internal testing, discovered another issue in
Spaceball drivers, worked directly with 3DCONNEXION and most recent driver
has been corrected on their end as well
