Freebody – Other Enhancements

Freebody vector toggle buttons

• Toggle buttons have been added to the

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

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

Charting

Vector vs. Entity, Relative Positioning

X-Axis Values for Vector vs. Entity Data Series can now be specified as a

position relative to a node or element in the model

• Select “Position” for the X-Axis value

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

element

Grid Line Colors

Grid line colors can now be controlled by the user

• Color for both X and Y axes is controlled via

a single setting

• Minor gridlines are automatically assigned

a complimenting color

• For charts with dark backgrounds, the

specified color can be automatically

adjusted for easier visibility

• Femap line styles specified in the color

are observed in the grid lines

Example model with 1,000,000 elements, 1,030,301 nodes, and 1,030,301 nodal

constraints with labels displayed.

• Ctrl+G of model went from 15 seconds in regular Open GL Graphics using

Vertex Buffer Objects (VBOs) to 1.5 seconds (10x improvement)

• Dynamic rotation went from an average frame rate of 0.06705 frames/sec in

regular Open GL using VBOs to an average frame rate of 5.36635

frames/sec (80x improvement)

• Nodal Loads – Added 12/2014

• Elemental Loads – Added 1/2015

Femap 11.2

Overview


• Geometry tools

• Preprocessing

• Meshing

• Solver support

• Postprocessing


• Miscellaneous

2015-05-19



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)

2015-05-19




File | Attach to Results command

• Increased number of output files which can be selected for attachment in a

single instance from 1,000 to 20,000

Data Table/Entity Editor

• Added number of mesh seeds on curve to entity editor/data table.

Tools, Unit Conversion

• Added support for unit conversion of Connection Properties.

API

• Removed feOutputTransform (Must now use feOutputTransform2)

• Added the Analysis Study object and several methods

• Added methods to create “virtual” envelopes/combinations to Output Set object

• Added feCurvepad, feCurveOffsetCurveWasher2, feMeshUnzip2 and many

others

2015-05-19




View, Visibility command

• Added “Hide” button to Solids tab to allow graphical selection of Solids to hide

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

Femap 11.3 – Projects In Progress

Planned 2015 Year-End Release

Overhaul of Contour Vectors

• Updated GUI to enhance user experience

• Implement “on-the-fly” transformation of output vectors

• Potentially add additional options for display (i.e., show CBUSH forces using

individual element Coordinate Systems, not a single Coordinate System)

Overhaul of Entity Picking

• Updated GUI to reduce need to use “Method” menu

• Enhanced Face Picking

• Potentially add new Picking Options (i.e., automatically select nodes of an

internal or external “loop”, element faces of a hole, nodes along an edge, etc.)

Update Data Mapping Algorithm

• Single algorithm used for both the Model | Load | Map Output from Model

command and Output Map Data Surface

• Potentially used for new “Results Probe Tool” (Femap 11.3+)

2015-05-19



Femap 11.3 and Beyond

Potential Future Projects

Leverage Parasolid “Variational Toolkit” (VTK) to enhance functionality of

existing geometry commands (for instance, removal of fillets)

Nastran PARAM Manager – essentially add read/write support for all PARAMs

Support entity IDs above 99,999,999 (requests coming from several large

aerospace customers)

Support ABAQUS ODB results file via File | Attach to Results command

ANSYS

• Update translator to support modern element types, where applicable

• Support RST results file via File | Attach to Results command

Implement “Hybrid Mesher” to create a combination of Hex, Tetrahedral, and

Pyramid elements in a single mesh
