• 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

type for all output sets in the study

2015-01-15



Postprocessing

Analysis Studies

On-the-fly postprocessing

• Envelope: specify output sets – immediately plot maximum/minimum

displacements, stresses…

• Expand Complex: animate complex output data without creating additional

output sets

• Combinations: similar to load case combination data surface – immediately

postprocess user defined output set linear combinations

Value Envelopes

• 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)

Postprocessing

Freebody Section Cuts

New Section Cut freebody display mode

• The user defines a cutting plane in the

model and the contributing freebody nodes

and elements are determine automatically

• Total summation location can be placed at

• Plane/path intersection

• Nodal centroid

• Static location

• Nodal and total summation vectors can

optionally be aligned tangent to the path

without having to create additional

coordinate systems

2015-01-15



Postprocessing


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

Additional options

• Slider tool can be used to move the cutting

plane along the length of the path

interactively within the available entities

• Section cut entities may be limited to a

specific group or selected from the entire

model, and can be limited to a search

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

• Clipped entities can either be included or

excluded from the summation calculations

Total Summation Vector and Nodal

Summation Vector(s) headers

• Force and moment vectors for total and

nodal summations can quickly be

toggled on and off without having to drill

down into toolbox

• Vectors style can be switched between

component and resultant

• Quicker to use and visually cleaner

2015-01-15



Postprocessing


Freebody nodal summation contribution direction

• 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 summable

contribution by reversing the sign

CBUSH Enhancements

Spring/Damper element updates

• Added CSys and From Property options to Orientation section, with CSys allowing the

user to select a Coordinate System from the drop-down directly on the element, while

From Property uses the legacy method of getting Coordinate System ID from the

selected Spring/Damper Property (Orientation CSys)

• Added Location and From Property options to Orientation section, with Location allowing

the user to enter a value for Spring/Damper Location directly on the element, while From

Property uses the legacy method of getting the Spring/Damper location from the selected

Spring/Damper Property (Spring/Damp Loc)

2015-01-15

CBUSH Enhancements

By moving the Orientation Coordinate

System to the element itself, a single
