OpenGL has changed since
OpenGL 1.1
• Graphics hardware for OpenGL 1.1
• Vertex Transformation (dynamic rotation)
• Pixilation – determine which pixels are drawn for a
primitive
• Hardware has changed
• Graphics hardware is massively parallel
NVIDIA K5000 has 1536 cores
• Graphics hardware has much more memory
NVIDIA 6000 has 6GB
• OpenGL has followed
• Allocate buffer objects (memory on graphics hardware)
• Use programmable shaders to tailor graphics capabilities
Unrestricted © Siemens AG 2013 All rights reserved.
Page 4 Siemens PLM Software
FEMAP Graphics Architecture v11.0
• FEMAP v11 includes support for Vertex Buffer Objects (VBOs)
• Require at least OpenGL 2.1
• Only need OpenGL 1.1 if VBOs not used
• VBOs enable vertex data to be stored on the graphics card
• Vertex data is location, normal and texture
• Drastically reduces data transfer per frame
• Limited by graphics memory
• More graphics memory means more performance
• Up to an order of magnitude performance improvement
• Dynamic rotation of large models

FEMAP Graphics Architecture Progress
Model Description Performance Improvement
1600 solids – each solid is a 100x1x1 brick
with the four long edges filleted to .1 radius
Model 1 in 10.3.1/64 with no vertex arrays
440ms, in dev 64 release 50ms (8.8 times
faster)
1600 solids – each solid is a sphere of
radius 1
Model 2 in 10.3.1/64 with no vertex arrays
1213ms, in dev 64 release 270ms (4.5 times
faster)
640,000 quad4 elements Model 3 in 10.3.1/64 with no vertex arrays
427ms, in dev 64 release 408ms but with VBO
on, 64ms (6.3 times faster) and uses about
151MB of graphics memory
1,919,488 tetra10s – 16 solids of
100x100x1 block – each block has
119,968 elements
Model 4 in 10.3.1/64 with no vertex arrays
746ms, in dev 64 release 750ms but with VBO
on, 130ms (5.7 times faster) and uses about
252MB of graphics memory

Limits of Performance on Dell Precision
Mobile Workstation
• I7-2860QM – 2.5 GHz
• 16 GB RAM
• nVidia M2000 – 2GB RAM Graphics
Multiple Copies of the Boeing ISS
Laboratory Module
4.5M Nodes and Elements
Dynamic Rotation Performance ~8x faster,
v10.3 to v11 w/VBOs

FEMAP Graphics Architecture Future (v11.1)
• Single copy of graphics entity data within a model
• Used to have a copy per view of model
• Significant <Ctrl-G> improvement as raw data already in
memory
• Dynamic rotation better than original not quite as good as VBO
• But can handle much larger models
• Phased introduction
• First release accelerates solids and plates
• Deformation, Animation
• Contour, Criteria
Unrestricted © Siemens AG 2013 All rights reserved.
Page 8 Siemens PLM Software
FEMAP Graphics Architecture Future (v11.1)
• Uses Geometry Shader functionality that requires OpenGL 4.1
• Moves facet generation from CPU to GPU
• Dramatic reduction in volume of data required
• Shader uses same data for filled faces or edges
• State changes done in GPU on the fly
• Such as shrink, plate thickness
• Deformation – faster animation generation
• Contour only faces with results – good for contact
• Contouring done in fragment shader
• Better quality near min and max contour values
• Better quality interior interpolation

FEMAP Graphics Architecture Future
V11.1 – OpenGL 4.0/4.1 Graphics
Takes advantage of Parallel GPU Processors, some graphics
cards now have 448 processors, in FEMAP v10.1/11.0,
FEMAP controlled processor utilization, now the graphics
driver optimizes parallel processor usage.
Not only are OpenGL 4.x graphics faster, they use
significantly less graphics memory –
Consider a block meshed with 34584 elements and 50975
nodes.
OpenGL 1.0 data requirement is 46x34584 = 1,590,864 floats
OpenGL 2.0 data requirement is 292x34584 = 10,098,528
floats
OpenGL 4.0 data requirement is (3x50975)+(10x34584)
= 498,765 floats

Geometric Modeling – Non-Manifold Add
Non-Manifold Boolean Add
• FEMAP v10.3.1 and
Previous – Parasolid had
no tolerant modeling
functionality for non-
manifold body, everything
worked at 1.0E-6 Precision
• V11.0.x add some Edge
Precision modifications, but
not full tolerant modeling

Geometric Modeling – Non-Manifold Add
Non-Manifold Boolean Add
• In close cooperation with
the Parasolid Team,
identified use cases, test

Boolean Add
• Now works similar to
Parasolid “Stitching” or
“Sewing”, bringing edges
and vertices together

Geometric Modeling – Non-Manifold Add
Non-Manifold Boolean Add Details
• Algorithm Starts with First body, and adds the
next closest body one at a time
• Tolerance – Similar to Stitch/Sew
• Incremental Checking – After each step,
checks to see if the resulting Parasolid body
is ok, if not, rolls back and skips that solid.
Depends on the quality of the geometry,
on this ship model, not required. On
others, it is. It’s slower with the check,
use it the first time, you’ll know if you
need it in subsequent models.

MSC Nastran -
Support HK (original) and Binary Tree ( MSC 2005 and later ) storage methods.
Method selected with DBCFACT on NASTRAN command
• 0 - no multi-key format (default) - This produces the original format XDB file
used by MSC and NX
• 2 - auto-select multi-key format - Data blocks possible in both formats
• 4 - multi-key format - Data Blocks are always written using the new Binary
Tree method.
All three options are supported.

FEMAP v11.1 – Modify, Project
• Added new commands –
• Modify->Project->Points and Modify->Project->Nodes
• Removed old commands on the Modify->Project menu that
already projected points and nodes to specific entity types
• Improved the projection algorithms to accept multiple
curves/surfaces to project onto, and to allow projection along a
vector in addition to "closest" for all types.
• Added the feProjectOnto() API method to access the new
capability and converted old API "project" calls to use the new
internal functions.

FEMAP v11.1 Performance Improvements
• Visibility Dialog Box – underlying code was
rewritten to more quickly populate the
Property, Material, Group selection boxes
• Enhanced load expansion from geometry
to a mesh for elemental face-based loads
on surfaces (Pressure, Heat Flux,
Convection and Radiation). Previously on
large models these could take a long time.
For example a model with 1,000,000
elements meshed on a solid that had 300+
surfaces with pressure loads on ~120
surfaces took around 5 minutes to expand
to the mesh faces. Using the new method it
takes between 2 and 3 seconds.

FEMAP v11.1 - Charting Enhancements
• Added new data series type: Value vs.
Value. Allows for plotting of quantities
such as applied force vs. displacement
at a specified location
• Reorganization of chart data series
dialog to only show relevant items
• Improved rendering when copying
charts to the clipboard at non-screen
resolutions
• Increased user control over
fonts/labels/colors for chart entities

Other Updates
• Freebody: added ability to force freebody calculations to only consider
applied, constraint and multipoint constraint forces from GPFORCE data
block. By default, Femap will use applied, spc and mpc forces from OLOAD,
SPCFORCE and MPCFORCE requests if that data was not available in the
GPFORCE block, however there were some cases where Nastran would not
report the same number in both places (thermal applied loads across rigid
bodies being an example)
• Freebody: added validation tool to check if all requested values exist in the
result set
• Freebody: updated freebody listing tools to provide more relevant output
• NASTRAN: enhanced restart support
• NASTRAN: added support for Normal Modes Analysis with Design
Optimization

Performance Graphics
• Currently handles Shell and Solid Elements, expand to all
element types
• Additional Post-Processing Options, initial release supports
contouring and criteria plots, but does not accelerate special
post-processing options like iso-surface
• Use Performance Graphics data to great accelerate picking
