Femap v10.1.1 What’s New



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



Bearing Load



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.



User Interface – Selection

Filters on Selection

Previously produced a selection box with the IDs and Titles of entities being selected

Filter on “Stiffener”



User Interface – Polygon Picking Enhancement

Direct Access to Polygon Picking

In any Selection Box, Ctrl-Shift + Left-Mouse-Button activates Polygon Picking



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.



New “Pad” Alignment Options

Improved mesh control with new Pad Alignment OptionsAutomatic (Aligned to the Original Hole)Tangent to Selected CurveVector Aligned



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



NX Nastran 7

Femap 10.1.1 includes NX Nastran 7 as the integrated solver in Femap with NX Nastran

NX Nastran 7

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

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



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

TheoreticalSOL 601



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



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.
