Setting up Stopping Criteria for Topology Optimization
To control the run, you create solver-specific stopping criteria for both the primal and adjoint solvers.
- To create stopping criteria for the primal solution, right-click the node and select New Criterion or New Monitor Criterion. Provide the properties that the criterion requires according to your simulation.
-
To create stopping criteria for the adjoint solution,
right-click the and select New Criterion or
New Monitor
Criterion. Provide the
properties appropriate for your simulation.
Unlike other adjoint problems, topology optimization benefits from frequent recalculations of the primal and adjoint flow. As such, the stopping criteria for the primal solver and adjoint solver should be set loosely, performing either a small number of iterations or dropping the residual by only 1-2 orders of magnitude.
