Initialization Options
To access the options shown in the following table, double-click the Memetic system on the Scenery pane and switch to the Memetic tab.
| Algorithm | Description | ||
|---|---|---|---|
| Outer optimization | Uses an Evolutionary Algorithm as the algorithm for outer optimization. To modify the algorithm settings, click . All parameters (discrete and continuous) are used for this optimization. | ||
| Inner optimization |
Selects one of the following algorithms for the inner optimization:
To modify the algorithm settings, click . The inner optimization only uses continuous parameters by default. You can use parameters that are discrete by value or discrete by index can be used by select the and check boxes. Nominal discrete parameters are kept constant. Only the Evolutionary Algorithm is recommended when using discrete parameters. | ||
Additional Options
To access the options shown in the following table, in any tab, click .
| Option | Description |
|---|---|
| Limit maximum in parallel |
Controls the resource usage of nodes in the system. When the check box is cleared (default), a value is chosen to ensure the best possible utilization of the child nodes. When the check box is selected, set the value manually to specify how many designs are sent to child nodes, limiting the maximum degree of parallelism for all children. Ansys recommends keeping the check box clear. |
| Auto-save behavior |
Select one of the following options:
The project, including the database, is auto-saved (depending on defined interval) after calculating this node/system (either when the calculation succeeds or fails). By default, all parametric and algorithm systems have selected, all other nodes have selected. |
