The Insulated Gate Bipolar Transistor (IGBT) compact model is now composed of an Electrical Element and Two-Resistor (2R) component compact models, providing an efficient representation of the IGBT element. 

The IGBT element can be described by specifying thermal resistances from the junction to the top or bottom. A set of I-C charts for different temperature values can also be defined for detailed analysis and characterization by users. 

The IGBT edit definition dialog allows users to easily add the model to a specific analysis. The junction temperature is used to determine the Electrical Power from the I-V chart, which is then applied to the model through the 2R component. 

The Cartesian Mesh Generator in Simcenter FLOEFD for Solid Edge ensures optimized performance, delivering faster meshing while utilizing fewer resources. With accelerated operations, including import and Smart Printed Circuit Board (PCB) mesh generation, overall efficiency is improved with quicker meshing and simulation workflows. The improved visualization capabilities and seamless updates after parameters are changed further enhance the overall workflow. 

Enhanced structural analysis 

Simcenter FLOEFD for Solid Edge can be connected to Simcenter 3D (SC3D) Nastran solver, unlocking nonlinear analysis power. The SC3D Nastran solver 401 introduces additional settings in the Calculation Control Options, allowing fine-tuning of simulations. The settings include adjusting scratch memory, refining contact mode, controlling solver steps, setting the end time and exploring large displacement scenarios. The enhancements also provide greater flexibility and control in nonlinear analysis and greater accuracy when working with large displacements. 

Tolerance-Based Contacts allow for precise simulations with improved contact options. Tolerances can be specified to create contacts between gapped bodies, linear and angle tolerances can be defined, and glue contacts can be seamlessly created to ensure accurate and reliable simulation results. 

The User-Defined Maximum Aspect Ratio in Local Meshing feature enhances structural meshing with increased precision. By specifying maximum aspect ratios for specific components, efficiency can be improved with greater control over the meshing process, especially for thin structures. 

Additional enhancements 

With the powerful Component Explorer, users can manage component attributes, experience streamlined organization and employ efficient component management. Thermal component lists can be exported and imported, allowing for easy editing of properties like material, volume source value, Two-Resistors (2R) power and Light-Emitting Diode (LED) current. Users can simply export the component list to Microsoft Excel, make any necessary changes and then seamlessly import the list, simplifying their workflow.  

Teamcenter FLOEFD item customization provides increased flexibility and adaptability. Users can customize the data model of Simcenter FLOEFD for Solid Edge to align specific requirements and conveniently store FLOEFD data model files using either local storage or Teamcenter storage. This customization can also seamlessly integrate FLOEFD into an existing data management system. 

Simcenter FLOEFD for Solid Edge’s enhanced Linux solver now supports co-simulation with Functional Mock-ups (FMUs) exported from other software, allowing for integrated and comprehensive analyses. This solution ensures smooth compatibility and enables users to leverage all essential information, stored within the FMU exported from FLOEFD, including model geometry.

All of these new features and enhancements in Solid Edge 2024, along with many more, were announced during our live premiere on October 11.
