Comment résoudre un problème d'optimisation topologique ?

Remarque : Le contenu de cette page est en anglais et sera traduit ultérieurement en français.
After completing the steps outlined in Comment créer un problème d'optimisation topologique ?, the description of the optimization problem is complete. Then, to run the topology optimization procedure:
  • While in pre-processing, click the Solving menu;
  • Select the command Run Topology Optimizaton.

At this point, Flux 2D will display the Run Topology Optimizaton dialog box and ask for the following data:

Figure 1. The Run Topology Optimization dialog box.
  • The Faces to optimize, i.e., a list of geometrical faces representing the parts of the device that will be subjected to optimization.
  • The Solving scenario previously created;
  • The name of the Working directory that will store data generated by the Flux-OptiStruct coupling during the optimization procedure;
  • The Optimization problem previously described;
  • The Topology optimization method to be employed. Two options are available from the drop-down menu:
    • the Density method and
    • the LevelSet method.

Once all the required data has been provided, click OK to launch the topology optimization. Flux 2D will them invoke the OptiStruct coupling and a new window will appear, displaying the OptiStruct iterations until convergence (or until the maximum number of iterations configured in the Optimization options has been reached).

Remarque : It is possible to interrupt the optimization during its execution by simply closing the OptiStruct window displaying the iterations.
Important : Before running the topological optimization in a project, verify if OptiStruct was properly installed in your system and if Flux Supervisor was correctly configured with its path. Further information is available in the section Software requirements.
