A .db can be a reference file for a Mechanical APDL object.
A Mechanical APDL object is used to open the Traditional ANSYS interface from the project schematic.

You can open a .cbd file with Finite Element ModelerFinite Element Modeler can be used to investigate the model and convert the model to a ANSYS Mechanical model.
Finite Element Modeler can be used to parametise an input mesh

Geometry is not only the starting point of a Workbench based structural simulation.
Multiple finite element models can be assembled and leverage all Mechanical functionalities, including contact detection.

Multiple WB systems can also be combined. Geometry, Mesh and Named Selections are retrieved.

• Combine pre-existing models, meshes, and geometries
• Update connections, define loads, solve in Mechanical
• Define transformations and copies in the assembly

Allows user to split then later re-assemble model
Original AssemblySub-Assembly models can be worked on
independently, and later assembledUpper Sub-Assembly
Lower Sub-Assembly
Shaft/Connector Sub-Assembly
Sub-Assembly models are updated separately
at project level

You can use Mechanical as a standalone post-processor.
• Combine External Model with Mechanical.
• Use Mechanical Tools > Read Results Files
