Femap Version 10 What’s New


Femap Version 10 What’s New

What’s new Meshing New mid-surfacing method Stress and displacement transformations Graphics FEM mesh geometry association


Femap Version 10Focus: Improved Finite Element Meshing

What’s new 3D solid and surface meshers Interactive mesh generation and verification New robust mesh improvement toolsBenefits Improved accuracy of FEA results with

higher quality meshes Reduced modeling times with more intuitive

workflows Easier to use with more automated meshing

and simulation processes Optimized modeling processes with

increased modeling fidelity where it’s needed to ensure efficient analyses and faster turnaround times


Femap Version 103D Mesher

New meshers implemented to create top quality meshes first time Meshes in 3D space rather than parametric space Overcomes meshing obstacles such as poles


Femap Version 102D Mesher

Improved meshing on curved non-planar surfaces

Mesh algorithms have been improved, and the meshers have been expanded to automatically apply multiple mesh approaches resulting in the best possible mesh without user intervention

Mesh options are saved for easy re-meshing


Femap Version 103D Solid and Surface Meshers

Internal and branching faces and curves are accounted for within a solid Create a consistent mesh in

volumes containing 3D, 2D, and 1D entities

Example: Reinforced concrete model:

steel beam elements with concrete tetra elements in a matched mesh


Femap Version 10User Interface

Meshing Toolbox – centralized placement of geometry cleanup and meshing functionality in a new pane Feature suppression and removal Combined and composite curves

and boundary surfaces Mesh sizing Mesh locate Mesh quality


Femap Version 10User Interface

Meshing Toolbox


Femap Version 10Geometry Cleanup

Meshing – Femap already provides world-class meshing functionality V10 adds interactive tools to quickly locate troublesome geometry and

clean it up, from a meshing perspective



Locator – curves/surfaces Short edges

Small surfaces, slivers, spikes



Feature suppression Feature removal



Interactive Geometry Manipulation Combined / Composite Curves



Interactive Geometry Manipulation Combined / Boundary Surfaces


Femap Version 10Geometry Manipulation

Geometry Splitters Subdivides surface geometry



Geometry Tools – Offset Curves and Washer Creates mapped meshing surfaces

Washer – with and without split lines

Offset Curves around multiple curves



With Offset Curves you can control mesh density where you need to around stress raisers Minimize model size Minimize analysis time Maximize accuracy of results

With Offset Curves you can control mesh density where you need to around stress raisers Minimize model size Minimize analysis time Maximize accuracy of results



Geometry Tools – Pad Creates mapped meshing surfaces Can be combined with Washer

Without Pad

Pad without mapped meshing

Pad with mapped meshing

Pad and Washer



Geometry Tools – Washer and Pad Use of these meshing tools

not only improve local mesh but can have a significant effect on the overall mesh of the structure


Femap Version 10Interactive Mesh Editing

Interactive Meshing and Mesh Editing Updated Mesh Size on Curves Interactively Display Element Quality

Feedback



Interactive Meshing and Mesh Editing Interactive Node Updating

Slide on Surface Slide on Curve

Interactively Display Element Quality Feedback



Mesh quality control

Improved mesh reporting



Combining the use of these tools can bring about top quality meshes with minimum effort


Femap Version 10Improved Geometry Handling – Shells

Create contiguous meshes through complex geometry intersections Non-manifold geometry – instances

where three or more surfaces share the same curve, e.g. T-junctions

Mesh will connect and match on all surfaces

Previously a limitation in Parasolid


Femap Version 10Improved Geometry Handling – Shells and Solids

Combine surface geometry and solid geometry making it easier to join solid and shell meshed components together

Internal faces have edges that are T-junctions

Tetra Mesher now handles internal triangles or quads, and creates a combined shell / solid mesh with slight embed for moment transfer.

This image shows a group with all the shell elements, and all the tet-elements that attach to them


Femap Version 10 Non-Manifold Geometry

Combining Non-Manifold Geometry and Offset Curves results in Exceptional Shell Meshing!!


Femap Version 10New Mid-Surface Modeling Method

Geometry / Midsurface / Offset Tangent Surfaces For true sheet metal parts


Femap Version 10Stress and Displacement Transformations

Transformations Displacements and stresses On-the-fly transformation options

For example: View just the radial component of a displacement in any cylindrical

coordinate system View hoop or longitudinal stresses


Femap Version 10 Graphics

More efficient face definition and storage Faster display Reduced memory use

Faceting Updated faceting gives

higher quality images Faceting match between

curves and surfaces


Femap Version 10 FEM Mesh Geometry Association

Associate Existing Meshes with Geometry Given Geometry Given Orphan Mesh

Femap will automatically associate the mesh with the geometry Nodes to Points Nodes to Curves Nodes to Surfaces Elements to Curves Elements to Surfaces Elements to Solids


Femap Version 10 API Extensions

New API methods added AddOutput on Data Table object feElementFreeEdge and feElementFreeFace on the Application object SelectID on all entity objects GetCentroid, GetEdgeNodes, GetFaceNodes, and IsParabolic on the

Element object


Femap Version 10 Other Features

Function definition graphs Cross section dimension comments –

bar/beam cross section dimensions are written as comments in the Nastran read/write

File open detection during read operation

Nastran single field format precision improvement

Direct access to SolidWorks parts and assemblies Quad pattern Quad_4Tria pattern mesh available in mesh editing Highlighting enhancement – highlights entities already selected when

activated Full Windows Vista support
