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

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

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

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.

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.

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

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

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

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

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

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

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
