Tutorials

Below is a list of short tutorial animations (no sound) that should help to get started more quickly.

Getting started

  • Create a new ProTOp input file and import the CAD model (FNF file)
  • Start and run a new optimization session
  • Export the resulting surface mesh
  • Manipulate the model view/display by using ProTOp graphics controls

Model preparation and import

  • Open an existing Creo part and review it briefly
  • Run ProTOpCI directly from Creo
  • Mesh an existing Creo part and export it into FNF
  • Run ProTOpCI manually and import the newly created FNF

Constraints and configuration

  • Open an existing (example) ProTOp input file and start the Model Configuration Tool
  • Configure the solid part as a lattice structure
  • Change the type of the lattice structure
  • Change the orientation of the tool coordinate system with respect to model coordinate system
  • Change the lattice cell size
  • Change the type of the tool coordinate system, from Cartesian to Cylindrical
  • Run the optimization process
  • Open an existing (example) ProTOp input file and start the Technological Constraints Tool
  • Impose two technological constraints
  • Create in an existing Creo part an additional artificial analysis (load case) and name it with anyname_EXPGEO; the _EXPGEO tag tells ProTOp that this load case contains geometrical data (surfaces) and that it should not be treated as a real load case
  • Run ProTOp manually and import the newly created FNF
  • Configure fixed and free regions by using the Material Regions Tool
  • Configure the solid part as a mixed shell/solid structure by using the Model Configuration Tool

Optimization

  • Start and run a new optimization session with some chosen volume part
  • Change the volume part and proceed with optimization
  • Change the targeting from volume part to stresses and proceed with optimization
  • Run elastic analysis
  • Switch to elastic-plastic analysis by setting the FEA.YieldStressFac
  • Run the first optimization cycle by using the double precision FEA solver (4 core i7 PC)
  • Change to single precision solver and run the second cycle (note the differences in CPU time and RAM consumption)
  • Run optimization from full material design by using the COARSE mesh model
  • After convergence switch to FINE mesh model and use the Start from ... tool to start from COARSE mesh result

Model finalization

  • Open an existing ProTOp generated surface mesh
  • Remove sharp peaks and pits by using the Remove peaks/pits tool
  • Smooth cut surfaces by using the Smooth cut surfaces tool
  • Remove bad/redundant triangles by using the Simplify tool
