Creating Modeling Domains Around an Imported Geometry
The majority of 3D CAD files include only the geometry of the product to be manufactured. For finite element analysis, however, you find yourself often in a situation where additional geometry is needed, for example, to analyze the flow inside or outside a device. The example in this section, involving the geometry for a loudspeaker enclosure, demonstrates how to create domains inside and outside an imported CAD assembly. The following steps are covered:
•
Importing a STEP file
•
Finding and deleting holes and other details from the geometry
•
Creating the union of all imported objects needed to generate a domain inside the objects
•
Using the Cap Faces operation to create a domain inside the enclosure
•
Creating a domain that surrounds the imported enclosure.
