2. Femap v10.1.1
Bearing load
Enhanced Total Load options
User interface enhancements
Full PCOMPG composite entity support
New solid visibility options
Geometry Pad alignment
Meshing control extensions
Ships with NX Nastran 7

3. Bearing Load

4. Bearing Load
Bearing Load expands to only the positively oriented faces A traction load can also be applied acting in the opposite sense to a bearing load

5. Bearing Load
Bearing Loads can be resolved normal to the surface they are applied to, or in a uniform direction Bearing Loads also have an included angle – 60 degree bearing load shown

6. Total Load Options
Force, Bearing Force, Moment, and Torque load types from Model / Load / On Surface command updated to use Total Load option by default
Allows you to take a total applied load and spread it across all of the selected surfaces
Example: Total Load of 100 pounds applied to a total of 7 surfaces, load distributed out automatically as shown at right

7. User Interface
File / Picture / Copy Desktop command added
Similar to File / Picture / Save Desktop except a picture of the entire Desktop is copied to the clipboard instead of a file
File / Picture / Copy Layout and File / Picture / Save Layout commands added
Similar to File / Picture / Copy Desktop and File / Picture / Save Desktop, except a picture of only the graphics area is copied to the clipboard or saved to a file
Delete, Model, Mesh on Nodes command added
Similar to Delete / Model / Mesh except nodes are selected instead of elements.

8. User Interface – Selection
Filters on Selection
Previously produced a selection box with the IDs and Titles of entities being selected
Filter on “Stiffener”

9. User Interface – Polygon Picking Enhancement
Direct Access to Polygon Picking
In any Selection Box, Ctrl-Shift + Left-Mouse-Button activates Polygon Picking

10. New Visibility Option – Solids
Control display of individual solids from the Model Info pane
Toggle on/off with a single click
Similar to all other visibility control in Femap
A right click brings up the All On, All Off etc.

11. New “Pad” Alignment Options
Improved mesh control with new Pad Alignment Options
Automatic (Aligned to the Original Hole)
Tangent to Selected Curve
Vector Aligned

12. Meshing – Mesh Control
Four-Corner Mapped Meshing Control automatically finds best four virtual corners
Mesh shown with and without automatic “corner” detection

13. Meshing – Rigid Elements
New RIGID Element definition methods
New Node At Center creates the independent node at the center of all the selected dependent nodes
similar to the Spider API command
Convert button converts a rigid element to an interpolation element and vice versa
Translational DOFs only open when converting from rigid element to interpolation

14. Meshing – Rigid Elements
Distance Weighting option added to the Update Interpolation Element dialog box
Displayed after clicking the “Update” button in Define RIGID Element dialog box.
Creates different interpolation factors for highlighted Nodes to Average based on their distance from the reference node
Multiple nodes must be highlighted in the list for this option to have any effect

15. Full PCOMPG Global Ply Support
If the Global Ply references are all populated for every ply in a layup or laminate then a PCOMPG entry is created
If even one Global Ply reference is left blank then a regular PCOMP entry is created

16. General Nastran Support
Added support to read the QVOL, CONV, PCONV, QHBDY, QVECT, QBDY1, CHBDYG, VIEW, VIEW3D, RADM, RADMT, RADCAV, and RADSET entries
Added support to write TABLEM1 entries when creating vs. Temperature functions using specific function types in Femap

17. NX Nastran 7
Femap includes NX Nastran 7 as the integrated solver in Femap with NX Nastran

18. NX Nastran 7
Linear contact
Automatic penalty factor
Improved performance: fewer iterations and reduced run time
Now supported by the iterative solver
Faster solutions for solid models

19. Linear and glued contact
NX Nastran 7
Contact Pressure Along Path
Linear and glued contact
Improved surface refinement with new contact algorithm
More accurate and robust solutions
Now able to assign local contact and glue parameters
BCTADD and BGADD combine multiple sets of differing parameters
BCTPARM and BGPARM allow local parameter control for penalty factors and penetration handling
Greater solution flexibility – e.g. allow penetration to be eliminated in one area and ignored in another

20. Optional output of DMIG matrix of final contact stiffness connections
NX Nastran 7
Contact reuse
Optional output of DMIG matrix of final contact stiffness connections
Reuse contact connectivity in subsequent solutions
Include the effect of contact without having to resolve contact condition
Saves solution time
Reuse contact from cylinder head bolt loads analysis in a dynamic analysis

21. Sussman-Bathe Rubber for hyperelastic materials
NX Nastran 7
Advanced nonlinear
Sussman-Bathe Rubber for hyperelastic materials
Allows direct use of uniaxial stress- strain data for material properties
Shape Memory Alloy (SMA)
Material model simulates the superelastic and shape-memory effects of shape memory alloys
Elements
PCOMPG (solver independent support already in Femap)
Numerical improvements
Improved modal frequency response for very large number of modes
Theoretical
SOL 601

22. Femap Thermal and Flow
Negative heat load thermostats
You can now set negative head loads when modeling a thermostat cooling process
Build Group File command
Add, remove or modify thermal groups without performing a TMG solver before mapping
Aim and align vectors displayed in Orbit Visualizer
Aim and align vectors are now displayed in the Orbit Visualizer in addition to the spacecraft triad

23. CAD Geometry Translator Updates
Added support for CATIA V5 release 19
Added support for NX 7
Added support to optionally read or skip blanked/invisible/hidden parts when importing NX 6 assemblies
Restored support for ACIS versions 7, 8, and 9, which had been removed in a previous version.
