The filter functionality in Model Manager is based on a tailor-made search syntax adapted for searching deep within a COMSOL Multiphysics simulation model. You may have seen examples of this syntax already in the Filter query preview field in
The Filter Dialog Box. The syntax enables you to write filter queries that find models whose node properties, parameters, features, and other settings satisfy arbitrarily complex constraints. As an example, you can write a custom filter query that matches all models that have an axisymmetric 2D component, for which the component uses a particular physics interface and a particular material.
