1.SFE CONCEPT™ Powerful tool for evaluation and optimization of multiple designs

Present situation for product research and development in enterprises.With the rapid development of CAE technology, most enterprises have import digital process for product research and development, which includes product design—analysis and calibration—manufacture. Compared to conventional product design process, product design—prototype test—manufacture, it has more advantages. But problems still exists in it, including:

  • The product concept design is simply based on experience of the designers
  • There are a lot of geometric cleanup work to do after importing the CAD model to CAE software
  • The only role that CAE analysis plays is calibration
  • CAE analysis consumes too much time and avoids the possibilities of repeatedly calibrating
  • A lot of modification in late stage of design and manufacture causes cost and cycle problem
  • Barriers exists in exchange of data and knowledge between the analysis team and design team

Nowadays, enterprises have recognized the advantages of CAE analysis in design cycles, product quality and costs and also know the concept ‘analysis-driven-design’ can improve the situation of the enterprise. But to realize the concept, the problems below must be solved：

  • 1.
      Lack of CAD model data information in the early stage of design
  • 2.No way to take design details that significantly affect the performance of the product into consideration in the early stage of design
  • 3.Analysis model has no capability to make a quick response to the modification of CAD model
  • 4.Meshing is always time and human resources cost
  • 5.CAE model has no property of repeatedly reusing
  • 6.Optimization relating to changes of many parameters causes a huge computational quantity

3.Fetures of SFE CONCEPTTM

full parametric model

  • For a conventional CAD model, if a feature changes, the related features can’t identify the changes automatically and make changes. SFE can realize the adaptive changes related to a simple variable by the implicit relationship between features
  • Mesh can be upgraded automatically with the change of geometric model (including the function of morph but more powerful for morph can only works under small deformation meshing)
  • No need of geometric cleanup tools from geometric model to meshing
  • Fully parametric details design (ribs, imprints, punched holes, etc.)
Powerful built-in meshing tools

  • Creating parametric mesh automatically
  • Creating mesh according to the changes in geometric model in real time(10,000 mesh in less than 2 minutes)
  • FE model contains link information, material properties, load information and can be submitted to solver directly
 
 
Customized and modular intelligent model database

  • Rapid recreating, joining and modifying customized component, subassembly and assembly
  • Convenient for designers to call and modify for its modular structure
  • ‘Intelligent link’ keeps the geometry and topology correct
  • Ability to give a comprehensive evaluation of geometric model and the analysis results with repeatability.
  • Keep intelligent properties for enterprises; realize the reuse of models and platform strategy

 

Links between components are created automatically

  • Generate fully parametric joint between beams of any section shape automatically
  • Automatically generate design details (weld point, weld line and glue, etc.) that affect the performance significantly and make adaptive changes according to the geometric changes
  • Generate adaptive mesh at link automatically
Realize a FE model with zero initial interference

  • Automatic detection and definition on multiple levels avoid initial interference effectively
  • Detection and automatic removal technology of initial interference on mesh
  • Improve quality of mesh

 

 

Parametric closed cycles process

  • Describe complex changes on topology and geometry with several design variables
  • Design variables can be continuous or discrete
  • Interfaces to a variety of popular CAE software
  • Generate a closed loop with FE solver and outer optimization tools
  • Optimization results drive the updates of geometry and topology automatically
