Load the package:

Create a numerical region of a full region in two dimensions:

Extract the bounding box:

Extract the predicates:

Extract the embedding dimension:

Create a numerical region of a disk and extract the predicates and the predicate variables:

Extract the symbolic region:

Extract the boundary function:

The boundary function returns a value for which the zero contour is the region boundary, negative inside and positive outside.

Plot the boundary function:

Create a numerical region from an implicit region:

Extract properties from the numerical region:

Create a numerical region of a full region in two dimensions:

Extract the ElementMesh:

Create an ElementMesh with ToElementMesh:

The ElementMesh field is now populated:

The boundary ElementMesh is now also populated:

Clear the meshes and constraints:

Create a numerical region of a full region in two dimensions:

Initially, boundary and element meshes are not populated:

Create a boundary mesh:

The boundary mesh is now populated:

Create a mesh:

Define a NumericalRegion based on the mesh:

Retrieve the predicate and the symbolic region of the NumericalRegion:

Retrieve the bounding box and variables:

The meshes are the same:

There is no boundary mesh associated:

Not all string properties are available for all input:

A way around that is to use exact numbers as input:
