• Loads
  • Forces are specified per object (volume) and distributed evenly over this object.
  • For a surface load, the active surface with thickness 0 must be loaded as a separate object (.STL file).
  • If only a single force is to act as a point load, a separate (very small) volume must be generated for this. Here it should be pointed out that an idealized point load in reality always corresponds more to an area/volume load!
• Fixtures
  • Displacements can be locked in the x, y and z directions.
  • The activation of all displacement restrictions corresponds to a fixed fixture.
  • A floating bearing can be created by selecting only one or two displacement restriction(s).
  • For optimization, each direction must be locked (activated) at least once on any object, so that no rigid-body movement can occur. (Exception when using symmetry, see below).
• Moments
  • Moments also affect entire objects and can be defined in x, y and z directions. The right hand rule can be used to imagine the direction of rotation.
    

Load Cases

All created boundary conditions are listed in the Load Cases area. Selecting a load case marks all active boundary conditions. In the same way, individual boundary conditions can be activated by clicking and thus assigning one to the load cases.

The corresponding force arrows in the visualization area also adapt to the selection of the load case. Before starting, the optimization model can be checked for completeness and selection of the correct boundary conditions in the respective load cases and adjusted if necessary.
