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

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

Femap by creating an acceleration load and exporting a static analysis
• Added read/write of Femap comments as titles for Connection Regions,
Connection Properties, and Connectors
• Added read/write of Femap comments as titles for Combined Load Sets -
Force, Moment, Pressure, and Grav
• Added read/write of Femap comments as titles for Combined Constraint Sets -
SPC, SPC1, MPC, MPCADD, and SPCADD

Miscellaneous Enhancements
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)
Geometry
• Added ability to delete surfaces that are part of Solids and it automatically
changes the original solid into stitched sheet solid
• Enabled “Geometry, Midsurface, Single”, “Single in Solid”, and “Trim to Solid”
commands to work with non-manifold bodies.

Miscellaneous Enhancements
Spaceball
• 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
• December 2014 – During Femap internal testing, discovered another bug in
Spaceball drivers, worked directly with 3DCONNEXION and most recent driver
has been corrected on their end

Miscellaneous Enhancements
Geometry | Surface | NonManifold Add
• Update command to include Express option which can greatly increase the
performance of the NonManifold Add process as it is all done using a single
call to the Parasolid engine
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
