ANSYS DesignModeler

All engineering simulation starts with geometry to represent the design. This could be a solid component for a structural analysis or the air volume for a fluid or electromagnetic study. This geometry has been produced in a computer-aided design (CAD) system or built from scratch. ANSYS DesignModeler software is the gateway to geometry handling for analysis with software from ANSYS.

ANSYS DesignModeler has connections to all major CAD systems, allowing seamless transfer of existing data including parameters. The parameters can then be adjusted and the design updated, and any feature removal or simplification is maintained. This results in rapid turnaround of any design changes and updates.

CAD models are often designed for manufacturing use and not for simulation. Using CAD models results in a complex geometry that includes details not needed for simulation such as logos and other small features. Simulating such a fully detailed model will increase solver run times. It can be more efficient to spend a short time removing these details to reduce the total run time by hours or days.

ANSYS DesignModeler technology also provides powerful tools for construction of geometry from the ground up. A complex model can be produced using familiar solid modeling operations. Built on the Parasolid® kernel, the geometry engine is robust and conforms to industry standards. Two-dimensional sketches can be extruded into 3-D solids and then modified with Boolean operations. A construction history is recorded during the creation of the geometry, allowing the user to make changes and then update the design.
Whether importing an existing CAD model or building one, the ANSYS DesignModeler product is fully parametric. Combine this with parametric meshing and parametric solver setup within the ANSYS Workbench platform and the same geometry can be used for multiple design variations.
