Dassault Systèmes’ CATIA Analysis products are ideal for designers wanting to evaluate their designs. Many products are subject to thermal loads, as well as structural loads, or are made of materials like rubber that are inherently nonlinear. Designers also want to study the effect of overload conditions when the product might suffer permanent deformation. Many users have therefore asked that the CATIA Analysis products be enhanced to include thermal and basic nonlinear analysis.
To access the basic nonlinear and thermal analysis capabilities included in ANL and ATH, users must
first be working with Generative Part Structural Analysis (GPS), the backbone product to the CATIA V5 Analysis offering. The GPS structural capabilities will be extended to include nonlinear effects that enable more realistic simulation, such as nonlinear material characteristics, large deformations, and advanced contact. For users looking to analyze nonlinear structural and thermal assemblies, they would also need to be working with Generative Assembly Structural Analysis (GAS) before adding ANL and ATH.
NonLinar Structural Analysis
ANL extends the capabilities of GPS and GAS to allow more advanced simulation that includes nonlinear effects, such as large displacements and material nonlinearity. Material plasticity, typical of metals, can be modeled, as can the nonlinear elasticity in hyperelastic materials like rubber. ANL also provides more advanced contact capability including the automatic creation of contact surfaces based on their geometric proximity. ANL allows designers and design engineers to understand the performance of components that are made of materials like rubber that have nonlinear responses. In such scenarios, the designs are flexible and undergo large displacements, or they sustain overload conditions when components might be permanently deformed, but must not fail.
ANL Product Highlights:
- Includes the effects of large displacements and rotations.
- Enables the permanent deformation of materials to be modeled.
- Models the nonlinear elasticity of rubber and other hyperelastic materials.
- Multi-step analysis enables analysis of multiple sequential loadings.
- Provides advanced contact capabilities, such as friction at contacting surfaces.
- Performs thermal stress analysis when used in conjunction with ATH.
ATH extends the capability of GPS and GAS, allowing designers to understand the thermal behavior of their designs. The steady-state or transient temperature distribution can be calculated in response to the direct heating of a surface, the flow of a fluid past a surface, or the specified temperature of the surface. The thermal material properties can be temperature-dependent. When analyzing assemblies, the conductivity across the interface between contacting parts can be specified.
ATH Product Highlights:
- Calculates the temperature distribution in apart or assembly.
- Determines the steady-state or transient thermal response.
- Material properties can be temperaturedependent.
- Allows the conduction of heat between parts in an assembly
