Ansys DesignModeler – Freeze & Unfreeze

The Freeze feature is an advanced modeling tool available from the Tools Menu. Freeze has two applications: it allows for an alternative method for assembly modeling with multiple body parts, and it allows you to slice a given part into several sub-volumes (for example, sweepable volumes for hex meshing).

Normally, a 3D solid feature operates like this:

The Freeze feature allows you to control the second step. It acts as a separator in the construction history as displayed in the Tree Outline. Any bodies created for features before a Freeze will become frozen. Frozen bodies are denoted by the ice cube icon next to a body under the Bodies branch of the Tree Outline. All frozen bodies will be ignored when it comes to the Add, Cut, or Imprint Material operation of any features following the Freeze.


In this tutorial, you will learn how to use Freeze and Unfreeze tools in Ansys DesignModeler. With this option you can unite fluid domains.

Tutorial: Mesh types (Hexa, Prism and Polyhedral).

The Thin/Surface feature allows you to convert solids into thin solids or surfaces. The feature can operate on both active and frozen bodies. Typically, you will select the faces to remove, and then specify a face offset that is greater than or equal to zero (>=0).

Some import types (ACIS and AutoCAD) allow you to specify the units of the imported model. Before clicking Generate, you may be able to change the model units from the Details View, depending on the type of import. Note that some model types store their units, so no Model Units property will appear when importing them.
