What is analysis in Computer Aided Design (AICAD)?

The goal of the design-through-analysis workflow proposed in the present publication, named analysis in computer aided design (AiCAD), is to use NURBS-based B-Rep models for the entire workflow, i.e. for geometric modeling, model analysis and postprocessing (see Section 2 ).

What are the different types of CAD simulation and analysis tools?

A common CAD simulation and analysis tool is finite element analysis (FEA). This is illustrates how parts and assemblies behave when dynamically loaded. Examples include stress, strain, structural and vibration testing. Another related field of analysis and simulation is computational fluid dynamics (CFD) for examination of fluid flow.

What is the standard output of geometrical modeling in Computer Aided Design (CAD)?

In industry the standard output of geometrical modeling in computer aided design (CAD) (see Section 2.1) is a non-uniform rational B-Splines (NURBS)-based B-Rep model (see Section 3 ), especially for free-form geometries. The predominant method used in the industry for solving structural problems is classical finite element analysis (FEA).

What is 3D CAD?

Other 3D CAD-based analysis and simulation techniques includes plastic injection mould flow and fatigue testing. CAD models are increasingly intelligent, where features and attributes can be attached to components and assemblies you design. This data can then be used to enhance testing or product development further downstream.
