In the optimization task editor, click the
Convergence tab.
Specify the Convergence Criteria. The following
options allow you to specify the convergence criteria for a sizing
optimization:
- Specifying when to start
checking for convergence
-
You can specify the iteration during which the
Optimization module
will begin to check the two convergence criteria. The optimization will always
continue at least until this value has been reached. The default value is 4.
- Specifying
which convergence criterion to check
-
You can specify whether the optimization should end when either of the
convergence criterion has been fulfilled or both of the criteria have been
fulfilled. The default value is that both criteria must be fulfilled.
- Convergence based on the change in optimization
function
-
You can specify that the optimization will end based on the change in
the objective function from one iteration to the next. The default value is
0.001.
- Convergence based on the change in element thickness
-
Element thickness is the design variable for a sizing optimization.
You can specify that the optimization will end based on the average change in
the element thickness from one iteration to the next. The default value is
0.005.
