2 2 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 What’s New What’s new  Meshing  New mid-surfacing method  Stress and displacement transformations  Graphics  FEM mesh geometry association

3 3 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 Focus: Improved Finite Element Meshing What’s new  3D solid and surface meshers  Interactive mesh generation and verification  New robust mesh improvement tools Benefits  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

4 4 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 3D 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

5 5 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 2D 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

6 6 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 3D 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

7 7 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 User 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

23 23 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 Improved 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

24 24 Copyright © 2008 Siemens Product Lifecycle Management Software, Inc. All Rights Reserved Femap Version 10 Improved 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
