Bearing Load

Page 3 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 4 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 5 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 8 Filter on “Stiffener” © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

User Interface – Polygon Picking Enhancement

Direct Access to Polygon Picking  In any Selection Box, Ctrl-Shift + Left-Mouse-Button activates Polygon Picking Page 9 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Options  Automatic (Aligned to the Original Hole)  Tangent to Selected Curve  Vector Aligned Page 11 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

Meshing – Mesh Control

 Four-Corner Mapped Meshing Control  automatically finds best four virtual corners Mesh shown with and without automatic “corner” detection Page 12 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 13 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 14 © 2010.

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 Page 15 © 2010. Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software

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 Page 16 © 2010.
