Topology Optimization
With a Topology Optimization analysis, you can compute an optimal structural design for a selected region of your model with specific design goals and constraints. Topology optimization is a physics driven optimization that is based on a set of loads and constraints.
Currently, you can use optimization to either maximize the strength of your topology, minimize
the response to free vibration, or both. You can also target a specified frequency, minimize
volume, or minimize stress.
Note: For Topology Optimization, the cylindrical
surfaces of bolts are considered protected regions, and bolt assignments are included in the
simulation. However, bolt preloads are ignored.
Attention: The Discovery
solver uses an elemental method to calculate factor of safety for the Minimize Volume
optimization goal. However, the monitor factor of safety uses a nodal calculation. As a result,
the resulting monitor factor of safety may appear to be lower than the value for the minimum
factor of safety. To ensure that the factor of safety constraint has been met, view the
%TEMP%/Discovery/{sessionId}/Logs/LiveTopologyOptimization_{sessionId} file. If the
complete optimization run is successful, SOLUTION FOUND FOR THE OPTIMIZATION PROBLEM appears at
the end of the file.
