Siemens Product Lifecycle Management Software Inc. All rights reserved Page 5 Siemens PLM Software 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 © 2011. Siemens Product Lifecycle Management Software Inc. All rights reserved Page 6 Siemens PLM Software 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 © 2011.
