Content Filters
Content filters match on values in the The Contents Section of Model Settings — that is, on node properties, parameters, features, and other settings in the model tree of a model.

Searching Nodes and Settings in the Model Tree
Parameter
The Parameter filter () is a combined Keyword Field, Text Field, and Numeric Field filter on parameters in a Parameters node. You can create a filter by combining:
•
The parameter name as a Keyword Field in the Name field.
•
The parameter description as a Text Field in the Description field.
•
The parameter expression, including units, as a Keyword Field in the Value field.
•
The parameter value, excluding units, as a real scalar Numeric Field in the From and To range fields. Leave one or both input fields empty to not set a corresponding bound.
The parameter value uses the unit system as set in the model when it was saved to the database.

Setting
The Setting filter () is a combined Keyword Field and Text Field filter on general settings found in the Settings window for a node. You can create a filter by combining:
•
The name of a setting as a Keyword Field in the Name field. This is an identifier of the setting that is not visible in the Model Builder, Application Builder, or Physics Builder Settings windows. You can find the name of a particular setting in the Name column in the Details dialog box for a node in The Contents Section.
•
The description of a setting as a Text Field in the Description field.
•
The value of a setting as a Keyword Field in the Value field.
•
The value of a setting when accessed via the COMSOL API as a Keyword Field in the API value field.
Not all node settings can be searched in the database. You can see which settings are available by, for example, finding a model that has the node type you want to search, select the node in The Contents Section, click the Details button (), and examine the rows in the Settings table in the opened Details dialog box.
Space Dimension
The Space Dimension filter () is a Selection Field filter on the space dimension of a Component node. Select from 3D, Axial Symmetry (2D), 2D, Axial Symmetry (1D), 1D, and 0D.

Physics
The Physics filter () is a Selection Field filter on physics interfaces used by a model. You select physics interfaces you want to filter on from a tree. Select a space dimension in the Show available physics for field to filter the tree on physics interfaces available for that dimension. You can also filter the tree by writing the name of a physics interface and clicking the Search button.

Study Step
The Study Step filter () is a Selection Field filter on study steps used by a model. Select the study steps you want to filter on from the shown list.
Study and Study Step Types in the COMSOL Multiphysics Reference Manual
Node Type
The Node Type filter () is a combined Text Field and Keyword Field filter for finding models with nodes of a particular type. You can create a filter be combining:
•
The node type as shown in the user interface as a Text Field in the Type field.
•
The node type as used in the COMSOL API as a Keyword Field in the API type field.
•
The node class as used in the COMSOL API as a Keyword Field in the API class field.
Click the Model Tree Node Text button () and select Type to see a node’s type in the Model Builder tree.
You typically include a filter on the API type or API class fields to narrow the search when the Type field alone matches too wide.
Node Properties
You can filter on node properties as shown in the Properties window for a node.
Label
The Label filter () is a Text Field filter on a node’s label.
Name
The Name filter () is a Keyword Field filter on a node’s name.
Tag
The Tag filter () is a Keyword Field filter a node’s tag.
Created
The Created filter () is a Date Field filter for when the node was created.
Author
The Author filter () is a Keyword Field filter on the node’s Author field in the Properties window.
The value in a node’s Author field is written as a general string value in the Properties window and need not correspond to any Users in a database.
Version
The Version filter () is a Keyword Field filter on the node’s Version field in the Properties window.
The value in a node’s Version field is written as a general string in the Properties window and does not correspond to any particular model version in a database.
Comment
The Comment filter () is a Text Field filter on the node’s Comments field in the Properties window.
Last Modified
The Last Modified filter () is a Date Field filter for when the node was last modified. Except for the root node, this field is only available from the model object via the COMSOL API. Only a subset of all node types automatically update this value.
Last Modified By
The Last Modified By filter () is a Keyword Field filter on the last modified by value accessible from the model object via the COMSOL API. Only a subset of all node types automatically update this value.
