Automatic Solid Geometry Preparation
Geometry and Meshing Considerations
 Analysts inherit CAD models that often contain difficult geometry
 Serviceable for CAD, but cause problems with FE meshing
 Affects mesh and element quality and hence solution accuracy
 Typical problems include:
 Sliver surfaces
 Short edges
 Narrow regions
 Close points
 Internal voids
 Difficult geometry has to be fixed before the model can be meshed
 Manual geometry clean up requires much effort and time
The solution: Femap’s automatic geometry preparation capability
 Greatly reduces and in many cases completely eliminates the need for
manual combination, suppression and splitting of geometry

Automatic Solid Geometry Preparation
 Automatic clean up allows:
 Easier meshing of complex 3D
models with problematic
geometry
 Easy removal of unnecessary
detail
 Geometry cleanup actions
performed automatically include:
 Combination of surfaces and
curves
 Suppression of small curves and surfaces
 Surface splitting at strategic locations
 User defined tolerance controls extent of
geometry changes

Free Body Display
Detailed Loads Postprocessing
Free body display
 “Purest” application of FEA
providing model load transfer
at a nodal level
 Provides the engineer with
detailed information about
the load distribution and
transfer in a structure
 Key information for strength
analysis and design
 A graphical display of this
data greatly improves
comprehension and speeds
up model postprocessing

Free Body Display
 Free body data is obtained from a combination of:
 Grid point force balance results
 Applied loads
 Constraint equation force results
 Force Balance must be selected
prior to analysis
