SIMULIA Analysis for Designers

Generative Part Structural Analysis

As the backbone of the CATIA V5 Analysis Solution, Generative Part Structural Analysis (GPS) allows designers to understand how their designs behave and to accurately calculate the displacements and stresses within the part under a variety of loading conditions. It also allows the vibration characteristics of parts to be assessed by calculating the natural frequencies and the associated mode shapes. Analyses can be performed on volume parts, surface parts and wireframe geometries.

Generative Assembly Structural Analysis

Generative Assembly Structural Analysis (GAS) extends the capability of GPS, allowing designers to analyze assemblies as well as individual parts. The analysis of assemblies, including an accurate representation of the way the parts interact and are connected, allows for more realistic and accurate simulation. The designer does not have to make simplifying assumptions about the loading and restraints acting on an individual part. Instead the part can be analyzed within the environment that it operates with the loading automatically determined based on the way the part is connected to and interacts with surrounding parts.

Generative Dynamic Response Analysis

While GPS and GAS allow designers to understand the vibration characteristics of their designs by calculating the modes and natural frequencies, Generative Dynamic Response Analysis (GDY) takes this a step further by allowing users to study the response of their designs to dynamic loading. This allows designers to ensure early in the design phase that their designs do not suffer from resonance and other dynamic effects.

Elfini Structural Analysis

Elfini Structural Analysis (EST) extends the capabilities of the GPS product to include multiple analysis cases for static, frequency, and buckling analysis. This product is more tailored to the needs of specialists, while maintaining a consistent user interface between specialists and design engineers. This common user interface promotes the teamwork between various disciplines to shorten the design analysis turnaround time.

Thermal Analysis

Thermal Analysis (ATH) extends the CATIA V5 Analysis capabilities, 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.

Nonlinear Structural Analysis

Nonlinear Structural Analysis (ANL) extends the CATIA V5 Analysis capabilities 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.

FEM Surface

FEM Surface (FMS) provides advanced meshing capability for complex surface and wireframe parts. Meshes generated on geometry are fully associative with the geometry and FMS provides more control and more sophisticated meshing algorithms than the standard surface meshing capability in GPS.

FEM Solid

FEM Solid (FMD) provides advanced meshing capability for complex solid parts. It is fully associative with the geometry and provides more control and more sophisticated meshing algorithms than the standard solid meshing capability in GPS.

Rule Based Meshing

Rule Based Meshing (RBM) extends the capabilities of FMS to enable automated and higher quality surface meshing for all workflows that use CATIA meshing tools. RBM gives the user a means to specify globally the desired meshing treatment of entities such as holes, fillets, and beads. RMB also gives the user a means to specify acceptable element quality criteria, such as minimum edge length, aspect ratio, and skewness. Once the complete set of meshing rules has been specified, no additional user involvement is necessary, as the actual mesh generation is completely automated.
