Analyst Tree-Clipping

Analyst Tree-Clipping allows you to remove or clip areas of the model that are currently not of interest.

A model can be clipped in three ways - using planes, slices, or domain boundaries. A clip group is a collection of one or more planes, slices or domain boundaries (though it can only contain clips of one type). A model may have any number of clip groups. For example, the model of a pipe may have two clip groups, one containing different slices of the pipe and another containing an area of pipe constrained by a number of planes.

Creating a Clip group

In the Analyst Tree, select the Clipping checkbox.

Click the + icon and select either Clipping Planes, Slices, or Domain Boundaries.

You can define the planes, slices, or boundaries in the lower half of the Clipping Elements section.

The top half of this section contains the list used to determine which elements within your model are affected by the clipping group. For example, you may want to only clip the geometries and leave the particles intact. By default, all the elements are included in the group. The elements are categorized by type - particles, geometry, and contacts. Select any element checkbox to remove it from the group.

The following figure shows a model of a pipe where a geometry has been included in a slice and particles have been excluded from the slice.

Clipping Planes

A planes clipping group can contain up to six individual planes. Select a plane from the Elements dropdown in the Clipping Elements section. The plane is then defined by its orientation and its distance from the center of the model. The section of the model that falls on one side of the plane will be clipped from the model. Simply negate the orientation of the plane to switch which side of the model is removed.

Use the Visual Representation option to display a preview of the plane in the Viewer. Select Enable Plane to activate the plane and clip a section from the model.

The following example shows a model before and after plane clipping.

 

Clipping Slices

A slices clipping group can contain up to three individual slices. Select a slice from the Elements dropdown in the Clipping Elements section. The slice is then defined by its orientation, distance from the center of the model and depth. The section of the model that falls outside the slice will be clipped from the model.

Use the Visual Representation option to display a preview of the slice in the Viewer. Select Enable Slice to activate the slice and clip an area of the model.

The following example shows a model before and after slice clipping.

 

Clipping Domain Boundaries

Each side of your domain can be used to clip your model in a Domain Boundaries clipping group. Select a side from the Elements dropdown in the Clipping Elements section and the select Enable Slice to clip the area of the model outside of the domain on that side.

The following example shows a model before and after clipping.
